Ceramic Si3N4 Diff Balls(Ceramic  Silicon nitride  Balls)

Ceramic Si3N4 ball with good ability of isolation and no magnetism is the precision ceramic that fired in high temperature without oxidation air,which has the high intension, high wearing resistance, high temperature resistance,anti-canker,strong acid and alkali resistance,can be used in seawater for a long time. At 800, the intension and rigidity almost couldn't be changed, whose density is 3.20g/cm3 and is the 1/3 of the weight of bearing steel. There are small centrifugal force when circumgyrating and  run at high speed.It also has the self-lubrication, and can be used in the environment with no lubricate medium and high pollutaion.which is the best material of Hybrid construction ceramic ball bearing.

The advantage of products
High Speed: Most of Freerun Miniature bearings can reach a resistance level of 50,000 RPM with grease lubrication.
------Long Service Life: The service life of Freeru miniature bearings is 4 to 6 times longer than other suppliers in comparable working conditions.
Self Lubricating: Even when poorly lubricated or with no lubrication, Freerun bearings will continue to function longer than other bearings under the same level of stress due to their self lubricating properties.
------Low Friction: Our bearings have a low friction force. Even under the conditions of boundary lubrication, the surfaces are extremely smooth, so its friction force is low and the rotational friction moment is low.
------Supply quickly from large Stock:  Over the years we have developed extensive product knowledge and offer technical help with all apsects of our range. We keep comprehensive stocks across the whole range so offer a same day despatch worldwide on most sizes if required. We receive incoming shipments every week so stocks are always changing.
