It has a certain combination of strength and toughness, so that the cage can bear a certain load and impact, and has better elasticity and stiffness.
The friction coefficient with the rolling element is small materials in INA Bearing, and the wear resistance is good.
It must have good thermal conductivity.
The specific gravity is small and the expansion coefficient is similar to that of the rolling element.
Because the cage structure is generally complex, the materials used are required to have good processing performance
The material of pressed cage shall have good plasticity and ductility;
The material of turning cage shall have good cutting performance;
Die casting cage material shall have good casting performance;
The material of injection molded cage shall have good injection molding performanc
Common materials of INA Bearing Cage and materials of rivets, washers, spacer rings, sealing rings, pillars and support pins
The commonly used materials for ina bearing cages, rivets, washers, spacers, seals, pillars, pins, etc. are divided into three categories: ferrous materials in INA Bearing (such as low carbon steel, stainless steel, etc.), non-ferrous materials (such as brass, bronze, aluminum alloy, etc.) and non-metallic materials (such as phenolic laminated bakelite, plastic, etc.).
Materials in INA Bearing Cages for special purposes should also meet the requirements of special working conditions, such as high temperature resistance, corrosion resistance, self-lubricating (used in vacuum) or non-magnetic, etc.
Pressed cages are often made of steel plates, sometimes copper plates. Compared with the metal solid cage, this cage has the advantage of light weight. The pressed cage occupies a small gap between the inner and outer rings of INA Bearing, and lubricating oil is easy to enter INA Bearing and remain in the cage.
The stamped cage is only written into the materials in INA Bearing code if it is not used as a standard structure.
The solid cage is made of metal, phenolic resin fabric and plastic. INA Bearing code generally indicates these materials.
Metal solid cages are used in workplaces with high strength requirements and high temperature.
Solid cages can also be used when retaining edges are required. The high-speed ina bearing cage at the flange is made of light materials, such as light metal or phenolic resin fabric, to ensure its small inertia force.
Polyamide (nylon 66) cage has very good sliding and self-lubricating properties.
The cage made of glass fiber reinforced nylon 66 is used for stable operation with the working temperature not exceeding 120~c.
