Product Description

Double row angle contact ball bearing is a new product developed by our company for iron and steel, mine, plate and high speed wire mill. In the process of development and trial production, the main problem is that the bearing clearance is not well controlled, and the design requirements can not be reached stably, and the set rate is low. Through the trial production of several specifications, we find out some rules and methods to solve the problem.



The use of the means is still the limit position sample. The center position of the inner groove is based on the small end face, and is controlled by the far and near two limit position samples. The center position of the outer ring two ditch is based on a datum trench center, and is controlled by the far and near two limit position samples. Main factors affecting the axial clearance.
