The rings (inner and outer rings) of the crossed roller bearing are the key components of the crossed roller bearing, and because the special design of the crossed roller bearing allows the rolling elements to be arranged alternately at an angle of 90°, the ring structure and processing accuracy are crucial to its performance. Crossed roller bearings are generally used in high-precision scenarios, so the crossed roller bearing rings also have certain requirements for accuracy. FTM can produce high-precision products and can select suitable materials, structures and processing technologies according to application requirements and drawing samples.
The following are the customized options for FTM crossed roller bearing rings:
Structural options for FTM crossed roller bearing rings:
1. Integral ring
Features: The inner or outer ring is an integral design with high rigidity, suitable for heavy-duty applications.
Advantages: Strong load-bearing capacity, high precision, suitable for occasions with large overturning moments.
2. Split ring
Features: The inner or outer ring is divided into two halves and assembled with bolts or fixing rings.
Advantages: Facilitates the assembly of rolling elements and improves production efficiency.
Material selection for FTM cross roller bearing rings:
Bearing steel (GCr15), stainless steel (440C, 316L), lightweight alloy materials (such as aluminum alloy or titanium alloy)
Reduce weight, reduce inertia, and improve dynamic performance.

Processing characteristics of FTM cross roller bearing rings:
The rings of cross roller bearings require high processing accuracy, and their raceways and dimensions must ensure precise contact with the rolling elements. The following are the main processing technologies that FTM can provide:
1. Turning: used to process the basic shape and size of the rings.
2. Grinding: Precision grinding of the raceway surface to ensure surface finish and geometric accuracy.
3. Heat treatment: To improve the hardness and wear resistance of the rings, quenching and tempering processes are often used.
4. Precision milling: Process the joint surface and bolt holes of the split rings to ensure the overall accuracy after assembly.
5. Coating treatment: Chrome plating or PVD coating treatment of the surface to improve corrosion resistance and surface performance.
Performance and functions of FTM crossed roller bearing rings
1. High rigidity and precision: The precision raceway of the ring provides stable rolling element support and achieves high-precision movement.
2. Carrying multi-directional forces: Due to the cross arrangement of rolling elements, the raceway design of the ring can simultaneously withstand radial force, axial force and overturning moment.
3. Durability and stability: The material and heat treatment process determine the life and wear resistance of the ring.
