Miniature Bearing Description                                                                                    

Freerun Bearing is special in making Miniature Flanged Bearing including( Stainless Flanged Bearing,Hybrid Ceramic Flanged Bearing)

Miniature Ball Bearings with flanged outer rings correspond to ordinary ball bearings with snap rings.The flange extends around the entire circumference of the outter ring due to the size limitation and to improve its running accuracy.Since it is not necessary to provide a shoulder on the housing bore if this bearing is used,the bore can be a sim..

Flanged miniature bearings are available open, shielded or sealed.with bore sizes as small as mm. The smaller sizes are sometimes referred to as instrument bearings.Available in SAE52100 chrome steel and AISI440C or KS440 (ACD34/X65Cr13) stainless steel, these metric sized deep groove radial flanged miniature bearings can withstand heavy radial loads and moderate thrust loadsin both directions. Flanged miniature bearings have an outer ring flange to facilitate location in a housing.

Many of these flanged miniature bearings can be supplied to order with ceramic balls (hybrid bearings).

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.

The Advantage Of Our Flanged Bearings                                                                                      

• High Speed: Most of Freerun Flanged Miniature bearings can reach a resistance level of 50,000 RPM with grease lubrication.
• Long Service Life: The service life of Freerun Flanged ball 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.
