Thrust bearings are designed for pure thrust loads, and can handle little or no radial load. The rolling element in a thrust bearing can be a ball, needle or roller.  Design units can be specified in English units of inches, metric units or both.  Important dimensions to consider when searching for thrust bearings include the bore, the outside diameter and the overall width.  The bearing industry uses a standard number system for bearings with metric diameter bores.  For bore sizes 04 and up multiply by 5 to obtain the bore in millimeters. If the bore is a hex this refers to the dimension across the flats.  If the bore is tapered this refers to the smaller diameter.  The outside diameter of the bearing includes the housing if it is a housed unit, but exclude the flange if a flanged bearing.

Bearing NO.

Thrust Rally Bearings is composing with seat circle, bear circle and steel ball and keep shelf three parts. Title axle cooperating with axle is enclose, cooperating with out hull is seat circle. accept the strength situation divides into the ball bearing of one-way thrust and two-way thrust ball bearing. One-way thrust ball bearing, can bear one-way axial load. Two-way thrust ball bearing 52 series are available, can bear two-way axial load. Two-way thrust ball bearing, among them enclose cooperates with axle. The installation of the seat circle person allies submit the bearing of the sphere, adjust heart performance, can reduce the influence of installing error. The thrust ball bearing can’t bear radial load, limit is relatively low in rotational speed. This kind of bearing is mainly applied to such trades as automobile, lathe, etc.

If there is any question of single direction thrust ball bearing. Welcome to contact us.
