40mm Single Extreme High Load Block
The XHL range has been designed to deal with extremely high loads without compromising on low load dynamic performance.
This has been achieved by combining the Allen dynamic bearing technology ? twin rows of stainless-steel ball bearings running on a stainless-steel axle ? with a plain bearing peek washer.
The result is a bearing system which can take extreme static loads without damaging the dynamic performance of the ball bearings.
Ideal for use in vang cascades or halyard turning points where static loads can be extremely high but low load dynamic performance is required.
We suggest using this block for the king-post rotation block (bottom vang block taking the full load of the vang) on a moth vang. This application is subject to extreme static loads so the XHL bearing technology is the perfect fit.
Features
- CNC machined aluminium side cheeks.
- Precision turned stainless-steel sheave.
