L68149/L68110 inch Tapered roller bearings

The clearance of tapered roller bearings before installation is “original clearance”, which is represented by C0, and “matching clearance”, which is represented by Cp, and “working clearance”, which is represented by Cg.

Under normal circumstances, the working clearance of the bearing is less than the original clearance and greater than the matching clearance, that is: C0 > Cg > Cp.

According to the characteristics of single-row tapered roller bearings, the relationship between working clearance and allowable axial clearance is as follows:

Cg=Ca Sinβ (mm)

Among them:

Cg = Allow working clearance

Ca = Allow axial clearance

Beta = contact Angle
