We make mini ball bearings for every type of application, including:Automotive, Medical, Industrial, Consumer Technology and Home Appliance industries.
For extreme conditions (high speed, high and/or low temperatures, high and low humidity, high loads). For high precision applications and critical security parts.
Miniature and small bearings are used for extremely high speeds. These bearings offer a low level of noise, vibration, and frictional torque performance.
Miniature and extra-small ball bearings can be sealed by shields or rubber seals to prevent leakage of lubricating grease or entry of dust. Since the appropriate quantity of a high quality lubricating grease is factory sealed, the sealed miniature and extra-small ball bearings allows simplification of sealing devices around the bearing and facilitates easy handling.
Sealing and Lubrication:
The most popular sizes of miniature and small bearings are also produced in sealed versions. These bearings with Z and ZZ are greased using high quality grease, lubricated for life and suitable for high speeds. Bearings with the suffix RS or 2RS have lip seals on one or both sides made from nitrile butadiene rubber. CRAFT bearings grease is a low noise bearing grease which is thickened by lithium 12-hydroxy stearic, it is made from deeply refined mineral oil with rust and oxidation inhibitors through special technical process.
