Please compare the difference of Huntsman Products rocker rollers to competitors. All our roller bushes are steel and not plastic that simply disintegrates. Our steel gives us on average 500kg higher rating by not using cheaper lower quality sources. All our spring bolts (roller and eye) come high tensile and are greasable.

SHOT PEENING
Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals and composites. It entails impacting a surface with shot with force sufficient to create plastic deformation. Shot peening is often called for in aircraft repairs to relieve tensile stresses built up in the grinding process and replace them with beneficial compressive stresses.
