1. The fiber-reinforced phenolic resin
Fiber-reinforced phenolic resin for precision angular contact ball bearing retainer cage standard material. This lightweight material having a high strength, centrifugal and inertial forces can be minimized to maintain the bearing lubricant. Fiber reinforced phenolic resin cage can operate in temperatures up to 120 ° C.
2. Nylon 66 (Polyamide 66)
With or without glass fiber reinforced nylon 66 cage for a variety of precision cylindrical roller bearings and angular contact thrust ball bearings. This material has good strength and elasticity. Since lubricated steel surfaces and smooth contact surface with excellent sliding properties, making nylon 66 cages has the advantage of low friction, less heat and low wear.
If not in contact with aggressive lubricants, nylon 66 can be used in operating temperatures of 120C or less. Aggressive lubricants (e.g., having a number of synthetic lubricating oils or EP additives) may lead to aging of the material, therefore by reducing the normal operating temperature to compensate for such effects.
3. Polyether ether ketone (PEEK)
Glass fiber reinforced PEEK as some precision angular contact ball bearing cage standard materials, but also applied to other bearings, mainly to achieve higher speeds. PEEK excellent performance makes the perfect combination of strength and flexibility, and can withstand high working temperatures, but also has a high resistance to chemical corrosion and wear resistance. Below 200 ° C, this material does not show signs of aging temperature or additives. However, precision bearings maximum operating temperature is limited to 150 ° C, since this temperature is the softening temperature of the polymer.
Many precision double row cylindrical roller bearings and direction angular contact thrust ball bearings use machined brass cages. Brass cage bearing lubricant is not generally used for impact, including synthetic oils and greases. Brass cage can operate at a temperature of 250 ° C or less.
