Our Advantage

· 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.
