Question: 1 / 400

When a bottom bearing block is resurfaced, what is the minimum thickness?

20.0mm

22.5mm

The minimum thickness for a resurfaced bottom bearing block is specified to be 22.5mm due to the engineering requirements that ensure structural integrity and operational efficiency. This thickness allows for sufficient material to withstand the operational loads and stresses that the bearing block will encounter during use.

Resurfacing a bearing block is done to restore its surface for optimal performance, and maintaining a minimum thickness is crucial to avoid compromising its strength. If the block were to be resurfaced to a thickness less than 22.5mm, it might not provide adequate support or might lead to premature wear or failure under the pressures applied to it. The design specifications and safety factors in calculations ensure that components like bearing blocks maintain this minimum thickness for both safety and longevity of the equipment they are part of.
