Series 55 Ball Bearing Orbit Block™ - Single - Becket - Swivel Head

Lightweight
Kilogram for kilogram of working load, BB and RT Orbit Blocks™ are the world's lightest. The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimises the mass of the inactive return race and hub.

Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible.

Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block.

Highest Working Load In Its Class
The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximises load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.

The floating sheave and bearing system is supported by a fiber-reinforced load frame. The design was computer modelled to be stress optimised. The Dyneema® Link is produced from FSE Robline SK75 fiber, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point.

Features:
  • Ultra Lightweight
  • Low friction 2-stage Orbital ball bearing system
  • Highest working load in its class
  • Low profile and compact
  • High performance cleating
  • Swivel shackle head for unlimited block rotation
  • Stainless steel shackle head for ultimate durability and compatibility with harsh fixing points
  • Ultra low profile integrated becket


Applications:
  • Mainsheet systems on dinghies, sportsboats and small keelboats to 9M(30')
  • Spinnaker sheets on dinghies, sportsboats and small keel boats to 9M(30')
  • Halyard, Vang and Backstay application on boats to 8M(26')
  • Control line applications on larger yachts
  • Ideal use for mainsheet systems and spinnaker sheets on dinghies, sportsboats and small keel boats to 9M(30')
  • Also ideal with halyard, vang and backstay applications on boats to 8M(26')
  • Spinnaker sheets on sportsboats and small keel boats (lateral lead blocks)
  • Control line applications on larger yachts

Series 55 Ratchet Mount Orbit Block - Cheek Anti-Clockwise Rotation

Features:

  • Up to 20:1 holding power
  • Smooth easing of sheets
  • High performance cleating
  • Automatic & manual ratchet block

Automatic ratchet block

Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself. Ronstan is the only company that offers a ratchet block with both auto and manual engagement modes*. In the auto mode of the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers. In manual mode, the ratchet mechanism can be switched on or off as required. This is the preferred mainsheet set-up for may top sailors. Try the block in both modes and see which you prefer - you really can't go wrong.

* Selected Series 55 models.

 Awesome ratchet block holding power

Quite simply, Ronstan Ratchet Orbit Blocks™ have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our patented sheave cross-hole geometry. Its holding power is up to 21:1, almost double that of our nearest competitor. The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designs have only 8 faces with an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimize rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load. 

Simple and secure attachment

The Dyneema® Link is easily fitted and is retained securely by a molded retainer clip. The flexible link can be left with one end attached to the block when fitting - no more lost shackle pins. The system is compatible with Dyneema®/Spectra® strops, webbing and caron connection points - much more so than steel loop tops or shackles. In auto mode, the sheet runs out smoothly and freely as soon as the ratchet mechanism disengages. In manual mode, the sheave cross-hole geometry eliminates the 'shuddering' run-out that you can expect from traditional v-groove ratchet blocks.

Materials:

  • Sheave: Anodized Aluminium
  • Ball Bearings: High compression strength carbon black Acetal
  • Frame/Cheeks: Toughened, glass fiber reinforced Nylon
  • Rope Link: UV stabilized, multi-strand impregnated SK75 Dyneema®

Series 60 Core Block™ - Single

Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.

Universal Bearing
Dynamic and high static load performance

The Ronstan Universal Bearing incorporates our proven 2-stage bearing system

Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.

Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.

Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn't perfect. Particularly important for cheek blocks.

Alloy Cheek Plates
Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimisation and the cut-away design minimises weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimising rope wear.

Universal head
The head assembly incorporates a brass bearing washer to provide smooth 360™ rotation of the post and shackle. A set screw arrangement allows the head to be locked at 0™ or 90™.

Shackles are high quality forged grade 316 stainless steel.

Features:
  • Class leading performance and sleek, contemporary styling
  • Excellent dynamic and high static load performance
  • Less than half the friction of the nearest competitor
  • Universal head with full 3-axis articulation
  • Head posts can be locked at 0 or 90 degrees, by using a 2.5mm Hex/Allen Key
  • Central hub hole can be used as a becket take-off or tie-up point


Applications:
  • Ideal for mainsheet, halyard and spinnaker sheet applications on boats to 12M (40')
  • Various control line applications on larger yachts

The Sheaveless Black

The obvious choice for those kitesurfers, paragliders, control line deflections and purchase systems that require a lightweight high load capacity block.

Ultimate durability

With no moving parts SHOCKS provide ultimate durability and are maintenance free. They are ideal where sand and grit would compromise a bearing system or where regular flushing out isn?t possible. Their gentle 3-dimensional geometry is kind on lines, but is strong enough to cope with poor leads.

Soft attachment specialists

SHOCKS are designed primarily for 'soft attachment'; spliced to a line end or lashed in place. The elongated attachment aperture is also ideal for webbing attachment, ensuring the intended orientation is maintained.

Virtually limitless applications

The applications for SHOCKS are virtually limitless, including numerous high performance dinghy and small sailboat rigging applications including tweakers, vangs, trapezes, cunninghams, barber haulers and kite bridles. They are also handy on larger boats for uses such as lazy jacks, sail covers, tie-downs, ladder and motor hoists.

Hidden performance

At a mere 2.5g (0.1 oz), SHOCKS are outstanding performers in the strength and weight stakes. The clever design and exacting finishing also provide excellent free running at moderate changes of angle. Small & hi-tech line specialists SHOCKS accept lines from 1.4mm (1/16") up to 8mm (5/16") and function just as well with hi-tech uncovered braids as with traditional double braids.

Engineered for Performance
Intensive development efforts have produced this high performance range of cam cleats that provides unbeatable holding power while allowing easy cleating and releasing of control lines and sheets.

Alloy Cleats™
Aluminium cam models built for ultimate durability where high wear and high loads are encountered. Cams are hot-forged and hard anodized for maximum strength and corrosion resistance. Ronstan Alloy Cleat™ models are available in sizes small and medium. The medium cleat is built on an aluminium base for maximum rigidity whilst the small cleat has a composite base for an optimum blend of lightness and durability.

Slotted Bearings
Self lubricating, self-cleaning slotted bearings provide lower frictional resistance, quicker response times and superior resistance to sand and salt than ball bearings which can deform under load.

Multi-Coil Spring
The multi-coil spring recessed in the upper part of the cam generates near constant torque. This consistency ensures secure cleating of even the smallest lines with minimal abrasion or rope wear.

Unique Teeth and Entry Profiles
Low effort line entry and exit due to unique teeth and entry geometry.

Advanced Composite Base
Small cleat has a base produced from long fiber reinforced polymer to save weight while providing essential stiffness.

Customization
A comprehensive range of specialist cleat accessories allow customization of the cleat set-up to optimize performance by controlling inward lead, outward lead, cleating and uncleating angle and height.

Total Control
Swivel cleat bases further enhance the function of cleats providing articulation, and with some models setting of cleating angle and direction (up or down cleating) to allow control of lines and sheets from various positions on the boat.
