Miniature Bearing Features
Miniature Bearings can sustain some axial load in either direction as well as radial loads, And the two raceway cross-sections are simple circular arcs which can be very precisely finished so the bearings have low friction and very little noise or vibration. Several different cage designs are available with different characteristics and the choice depends upon the individual application.

This Bearing Structure
Standard Type: A ball bearing is composed of an outer and inner ring, balls, seal and a retainer. Open type will no seal, Flanged type with flange side.
This Bearing Cover
Compared to the open type, the shielded and sealed bearing types provide better protection from contamination and grease leakage. They are selected based on the application type and environment. This is ZZ double shields.
This Bearing Lubrication
One of the most important elements required for the effective function of bearing arrangements is correct lubrication. The lubricant separates the metallic bearing surfaces and thereby reduces friction, preserves the steel parts and acts as an additional barrier against the entry of contaminations or impurities into the bearings.
This Bearing Cage
Retainers keep the balls separated and equally spaced. Retainer types are set based on the bearing size but can be selected based on the required performance. This is made of Nylon PA66 Cage.
This Bearing Material
The most common material used to produce the load carrying components in roller bearings is 52100 chrome steel (bearing steel). These components are the bearings inner and outer rings, balls and rollers. The chemical composition of this steel has high carbon and about 1.5% chromium content. Using controlled processing and heat-treating methods the finished bearing components have high strength to resist cracking and a hard surface to resist subsurface rolling contact fatigue. The typical surface hardness for bearing components made from this material ranges from 60- 64 on the Rockwell hardness C scale (Rc).
This Bearing Balls
Due to this usually very small contacting area ball bearings have less frictional resistance and are more suitable in high speed applications. This is made of 52100 chrome steel.
This Bearing Clearance
The term “clearance” is briefly described as the distance that bearing components may move relative to each other at physical extremes. CN (C0) “normal” clearance This clearance group is defined as the standard. Thus CN is not marked on the bearings. Historically the standard clearance was designated as “C0“. C2 clearance range smaller than CN C3 clearance range larger than CN
