4.Freerun Miniature Ball Bearing Lubrication                                                                                                                    
Oils - maintain their consistency well over a wide temperature range and are easy to apply. For very low torque applications, a light instrument oil should be specified. Higher running speeds are possible with oil but the obvious drawback with oil is the fact that it tends not to stay in place.
For anything other than very low speeds, continuous lubrication through oil mist, oil jet or oil bath is normally necessary. An exception to this is the use of a retainer (cage) that can be impregnated with oil such as the phenolic retainer. Perfluorinated oils can offer improved performance at slightly higher speeds as they don't migrate (run out) as easily.
Greases - are simply oils mixed with a thickener to so that they stay inside the bearing. Greases are generally more suitable for heavy loads and have the obvious advantage of giving constant lubrication over a long period without maintenance.
 


5.The Advantage Of Freerun Miniature Ball Bearing
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.
