Radial Internal Clearance - Bearing Works

Radial Internal Clearance. Internal clearance is the play within a ball bearing. It is the geometrical clearance between the inner ring, outer ring and ball. It is a critical factor in bearing selection that will directly impact bearing life. It is often overlooked, particularly as to how it is reduced by interference fits.

Plate Load Test:- Procedure, Bearing Capacity, Limitations, Calculation …

The test essentially consists of loading a rigid plate at the foundation level and determining the settlement corresponding to each load increment. The ultimate bearing capacity then takes as the load at which the plate starts sinking at a rapid rate. The bearing plate is squared, of minimum size, 30 cm 2 and the maximum size is 75 cm 2.
