SR133

SR133 Inch Size Miniature and small bearings feature deep groove geometries to achieve high speeds and support both radial and axial loads, providing low levels of noise, vibration and frictional torque performance. Miniature and extra-small ball bearings can be sealed with boots or rubber seals to prevent grease leakage or dust ingress.

Bearings with Z and ZZ are lubricated with high quality grease, lubricated for life and suitable for high speeds. Bearings with the suffix RS or 2RS have lip seals made of nitrile rubber on one or both sides. Aubearing grease is a low-noise bearing grease thickened by 12-hydroxy lithium stearate. Applicable temperature range -20 C – 120 C.

The slightly larger miniature bearings have a steel ribbon cage, while the smaller ones have a crown type. This SR133 Inch Size Miniature Ball Bearings are for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. For instance, SR133 is often used in motors, ATMs as well as Card Readers. In Food & Beverage Industry, SR133 is also popular. applications about SR133 are as follows.

General Selection Factors

Several factors must be considered for choosing miniature ball bearings. These factors include the ring material, design, shields and seals, cage, Annual Bearing Engineering Committee (ABEC) grade, radial play, and lubricant. Miniature bearings are available in open, sealed and shielded configurations. Seals and shields are used in miniature bearings (specifically ball bearings) to retain lubricants and prevent particulate contamination from reaching critical surfaces. Seals are used where minimal light contact is offered. Seals for miniature bearings provide deterrence to particulate contamination, but increase torque and limit operating speeds. Shields are used in most applications.
