(1) That part of a beam or truss that is in direct contact with its support. (2) Area of a load-bearing surface. (3) Angle of less than 90 degrees from either the north or south meridian, as measured by a surveyor. (4) Support for a moving part of a machine.
Bearing area
Area of a surface on which a force acts.
Bearing cap
The structural member between the top of a column and the bottom joint of another structural member, it is often larger than the top of the column so it serves to distribute the load.
Bearing life
Bearing life is measured in hours and the minimum life expectancy is measured by a control group under a prescribed set of conditions. The life expectancy of each bearing produced may be slightly different due to circumstances such as overall roundness, surface smoothness or tolerances. By measuring life expectancy under studied conditions, machine designs can be adjusted accordingly.
Bearing partition
Partition that is a vertical structural support.
Bearing plane
Surface that is load carrying.
Bearing plate
Metal plate that provides support for a structural member.
Bearing seat
The end of a beam or joist where the load is transferred to the member on which it rests.
