Dynamic Bearing Blocks - Allen

Allen's sailing blocks can be found in a variety of sheave sizes and styles ranging from 20mm up to 60mm.

Allen high performance sailing blocks use patented Dynamic Bearing Technology developed by Allen Performance Sailing Hardware. 

Twin rows of stainless steel ball bearings running on a stainless steel axle, offering fast rolling speeds, minimal friction and long last performance.

Allen also invented and patented Ultra-strap technology, a very narrow strap of high strength stainless steel, which can be lashed without fear of line abrasion associated with blocks of traditional strap construction. The Ultra-Strap provides a strong, reliable and rope friendly attachment point.

The variety of attachment options available in the Allen Dynamic Bearing Blocks range includes Beckets, Swivel, and Shackle attachment points. Additionally, they come in options ranging from single to quad blocks. 

Even though Allen's collection of ball bearing blocks and pulleys were originally intended for the sailing boat industry, they are versatile and suitable for a wide range of applications where a purchase system is needed to raise, lower, or pull an object.

Throughout the ball bearing blocks range you can be assured of quality, innovation and performance.
