Bearing cage material
The commonly used bearing frame and rivet and washer, spacer ring, sealing ring, pillar, a support pin, etc. materials are divided into ferrous metal materials (such as low carbon steel, stainless steel, etc.), nonferrous metal materials, such as brass, bronze and aluminum alloy, etc.) and non metal materials (such as phenolic clamp cloth bakelite, plastics, etc.) three categories. Special working conditions, such as high temperature resistance, corrosion resistance, self lubrication (using in vacuum) or non magnetic, etc., are also used for special purposes.
Stamping holder commonly used in the manufacture of steel, and sometimes with a copper plate. The holder has the advantage of lighter weight than the metal solid cage. The punch holder occupies a small space between the inner and outer rings of the bearing, and the lubricating oil is easy to enter the bearing and retain the inner ring of the bearing.
The punch holder is only written to the bearing code when it is not used as a standard structure.
The solid holder is made of metal, phenolic resin fabric and plastic. These materials are generally specified in the bearing code.
The metal solid cage is used for high strength and high temperature working occasions of the cage.
When you need to block the side boot, you can also use the entity to keep the. The retaining frame is made of light material, such as light metal or phenolic resin fabric, to ensure its small inertia force.
With polyamide (nylon 66) holder has a very good sliding and self lubrication properties.
Glass fiber reinforced nylon 66 made of the cage for working temperature is not more than 120 ~ C of the stable state of work.
When using lubricating oil, if there is an additive in the oil may affect the service life of the retainer. Bearing cage in the rolling bearing and the distance between the isolated rolling body and prevent the rolling body falling, guide and drive the rotation of the rolling body.
