Allen XHL Extreme High Load Ball Bearing Blocks


30mm XHL Extreme High Load Block


Allen 30mm XHL Extreme High Load Block


30mm XHL Extreme high load block.

The XHL is a new 30mm block with CNC machined, anodised aluminium cheeks, with a precision turned stainless steel sheave in a variety of dazzling colours.

It was designed for exceptional performance in classes such as the International Moth where extreme loads can crush the bearing surfaces of traditional blocks; this is taken up by a new extreme high load bearing system.

Tested by Team Allen sailors, the XHL is the ultimate block designed for the most testing race conditions experienced by today’s sailors at the leading edge of technology. With a weight of just 41g, a static load in excess of one tonne and a dynamic working load of 300kg, the XHL block is pushing the boundaries of small block performance.

XHL Bearings
Twin rows of stainless steel ball bearings running on a stainless steel axle with the addition of a protective plain bearing washer.

A key feature within the XHL bearing system is the precision plain bearing washer.
When the XHL is exposed to extreme static loads (which would normally cause damage to the internal bearing system) it changes to a plain bearing block. This stops the ball bearings from getting damaged and thus no longer performing as designed. As soon as the static load is reduced the XHL returns to a high performing dynamic block.

The aluminium body features “ears” at the top of the block. These are to be used when attaching the block and stop the block from capsizing when under load.

The stainless steel sheave allows the block to be paired with both rope and wire.

Nicely radiused to allow for a 5mm rope to be tied in the centre of the block.
Allows for an even pull and increased purchase system.
