⚙️core parameters:
The parameters of this model bearing of different brands may vary slightly.
Material: The rings and balls are made of GCr15 chromium steel, and the cage is mostly made of stamped steel; some stainless steel versions can be adapted for corrosive environments.
Load capacity: The basic rated dynamic load is approximately 1.99 - 2.3 KN, and the basic rated static load is approximately 0.72 - 0.89 KN. It mainly withstands radial loads, and can also withstand a small amount of bidirectional axial loads.
Speed and temperature: The maximum speed under grease lubrication is usually 23000 - 38000 r/min, and up to 38000 - 45000 r/min under oil lubrication; the working temperature range is generally - 20℃ - 120℃.
High maintenance resistance: The double-sided rubber sealing structure significantly reduces the wear of the internal raceway and steel balls by external contaminants. It is pre-filled with lubricating grease upon leaving the factory, and does not require frequent replenishment of lubrication under normal operating conditions, resulting in a long service life.
Wide application scenarios: As a miniature bearing, its compact size can easily be embedded in equipment with limited space; at the same time, the material and sealing design enable it to be suitable for various conventional environments such as household appliances, industrial small machinery, and others.
Optional precision versions: The regular products are mostly of ABEC - 1 (ISO P0) precision, and there are also some high-precision versions such as ABEC - 3, etc. With high-precision steel balls and finely ground raceways, the vibration and noise during operation are extremely low, meeting the high-precision and quiet requirements of scenarios such as miniature motors and medical tools.
