Bag of 20 Torlon balls, 4.76 mm - HARKEN

This compact packet contains 20 Torlon balls with a nominal diameter of 5 mm (3/16 in), perfect for optimizing the fluidity and longevity of your traveler cars, mainsail, jib, and ball-bearing blocks.

Diameter: 5 mm
Diameter in inches: 3/16 in
Quantity per packet: 20
Material: Torlon (high-performance thermoplastic polymer)
Manufacturer: Harken
Exceptional heat resistance, up to 260°C, much higher than most engineering plastics.
Excellent load capacity to optimize the performance of equalizers, pulleys, and ball bearings.
Remarkable dimensional stability, even in extreme conditions (humidity, mechanical stress).
Improved lubrication, reducing friction and maintenance thanks to the high-quality finish of Torlon.
Product from a leading manufacturer, Harken, renowned for its reliable innovations in performance equipment.

Replace the balls in your traveler cars when you feel them sticking; your sailing will gain in comfort, and some unfortunate capsizes could be avoided when gybing in strong winds with a smoothly running traveler car!

Our tips for choosing

Workload and breaking load

Choose your pulley based on the workload it will have to handle and the desired gear ratio. The orders of magnitude vary depending on the support: 400 to 500kg for the mainsheet or cunningham of an 18-foot catamaran, 100 to 200kg for the mainsheet or downhaul of a 420 dinghy for example.

Coefficient of friction

Modern ball bearing pulleys offer a much lower coefficient of friction than those without balls and are recommended for maneuvers that require constant adjustment (mainsail sheet, downhaul, cunningham, spinnaker essentially).

Restraining force

For the mainsheet which is not always fully tightened, or even never on some boats which require constant adjustment (29er, 49er, Class A,...) as for the spinnaker sheet, favor automatic or non-automatic winch pulleys, which considerably save muscles and gloves thanks to a retention that can go up to 70% of the workload.

Sheave diameter

Choose the diameter of the pulley according to the diameter of the rope it will guide. For example, depending on the support and workload, a 40 or 57 sheave is very suitable for a 6 to 10mm mainsail sheet. For Cunningham or downhaul type maneuvers, 16 or 22 sheaves are suitable.

Material

Stainless steel, carbon, composite, it's essentially a matter of weight, with an impact on the price: it all depends on the importance you attach to it. If the pulley is to guide a cable, use aluminum sheaves which will be much more resistant than composite materials.
