Unique straight warp construction Ply belt developed by Fenner Conveyors to deliver exceptional rip resistance and capacity to absorb extreme impact, with less stretch than traditional Ply belts.

Why choose UsFlex?

UsFlex uses heavy-weight straight yarns in parallel planes – lengthwise and crosswise – locked together with a unique binder to concentrate belt strength. Our unique binder to weft combination is a built-in breaker to resist impacts and punctures.

The best carcass available for impact and tear situations

UsFlex is our straight warp weave fabric belt carcass, engineered to provide incredibly high impact resistance, as well as industry leading resistance to rip and tear. Flexibility is gained through yarn twist and this delivers outstanding troughing ability and permits the use of smaller pulley diameters.

The low stretch properties of UsFlex make it an alternative to Steel Cord belts in many applications, combining the strength of a Steel Cord belt with the toughness of a Ply belt.

UsFlex has resulted in significant reductions in downtime and improvements in belt life in mining applications, solving for cord failure through impact or high edge tensions, or where rip resistance beyond traditional Breaker Fabric is required.
