Dynamic rating is used for calculations when the spherical plain bearing is subjected to dynamic stress.

The ffective service life is that life which will be attained by a given spherical plain bearing under actual operating condition.

The bearing contact pressure identifies the surface pressure occurring in the bearing.

It is necessary to distinguish between the internal clearance of a bearing before it is mounted.

The purpose of the lubrication is primarily to reduce wear, reduce friction and prevent scuffing

Most bearing arrangements must be sealed to prevent external contamination and damp from entering the bearing

Measurements taken of the outside diameter of the unfitted bearing cannot be used as the original actual values for the outside diameter.

In radial spherical plain bearings with split outer rings, the joints are offset at 90℃ from the main load direction.

The bearings must always be located concentrically.

Direct blows using a hammer and drift on the end faces of the bearing rings must be avoided.

Spherical plain bearings must not be heated above + 130 ℃,higher temperatures damage the seals.

But took notice that:The inner rings of spherical plain bearings with a steel/steel sliding contact surface undergo structural change at temperatures below -61℃.

it is not necessary to use adhesive on the bearing rings.
