Allen 20mm Dynamic Bearing Block with Swivel

The 20mm Dynamic Bearing Block with Swivel features a fork head swivel attachment that allows for rotation once attached. It offers low friction and high rolling speeds, making it a top choice for small diameter line applications such as dinghies, windsurfing, and kitesurfing. The patented bearing system uses twin rows of stainless-steel ball bearings and a stainless-steel rail, providing superior load-carrying ability and longevity compared to other bearing systems. Additionally, the block includes a large central rivet for reduced weight and a rope-friendly attachment for use in cascade systems.
