Miniature Bearing

A Miniature Bearing is a small ball type of bearing. Small ball bearings range in size from .1181 to 1.000 inch outside diameter (1mm to 26mm) and are available in inch and metric sizes, stainless steel or chrome steel. Also available flanged, open or shielded, depending on your application.

1) Types:Radial,Angular Contact,Full Complement,Thrust

2) Materials: Chrome Steel, Stainless Steel, Ceramic Hybrid, Plastic

3) Precision: ABEC-1 to ABEC-9

4) Seal Type: Open, Sealed(Rubber Seals), Shielded(Metal Shields)

5) Construction: Standard, Flanged, Extended Inner Ring

6) System of Measurement: Inch, Metric

7) Cages: Crown, Ribbon, Rivet

8) Noise: Performance Testing For Noise And Friction Torque Specifications Available.

9) Temperatures: Normal chrome steel miniature bearings can be used at constant temperatures of 120°C or intermittent temperatures of up to 150°C. Above these temperatures, the load capacity of the chrome steel will be reduced. By means of special heat treatment processes and the addition of high temperature grease, we can also customize miniature bearings for high temperature resistance.

10) Internal Clearance: Internal clearance is the play between outer ring, inner ring and rolling element. Generally, the amount of up and down movement of the outer ring with respect to the fixed inner ring is called the radial internal clearance and its right and left movement the axial internal clearance. Bearing internal clearance in operation is an important factor that has a significant influence on other factors such as noise, vibration, heat and fatigue life.
