Stainless steel chocks

SKF Vibracon

Stainless steel chocks (-SS series)
In harsh conditions, where requirements cannot be met by carbon steel surface treated chocks, the stainless steel chocks will be the solution. Mating surfaces are treated with additives to avoid seizing of the parts when rotated.

    1) Minimum reduced height can be reached by machining the centre and bottom part of the SKF Vibracon chock on a lathe. As a consequence of the reduction in height the adjustment range of the product will be reduced with the same amount as the total reduction in height.

    1) Torque values are valid for bolts with metric thread, material grade 8.8, yield strength >640 N/mm2, oil lubricated thread courses and nut mating surfaces without slide additives. Vibracon size ideally is matched to the related bolt size: SM 20 -> M20
    2) Optional bolt size. For an engineered solution, please contact vibracon@skf.com.
    3) Machine load is the sum of the weight of the component and the dynamic forces on the SKF Vibracon for the heaviest loaded position, multiplied by a safety factor.
    4) Proof load is the tested load which can be applied on the SKF Vibracon chock at maximum height before plastic deformation will occur. Exceeding the proof load will permanently
    deform the element, rendering it no longer adjustable. This is a tested load for SKF Vibracon surface treated chocks only.
