The RU Series Crossed Roller Bearing from FTM is a high-precision bearing designed specifically for applications requiring high load capacity and rigidity. As part of the crossed roller bearing family, RU bearings are unique because they feature integrated inner and outer rings with mounting holes, allowing for direct installation without the need for housings or fixing flanges.
Typically manufactured from high-strength materials like hardened stainless steel, certain custom crossed roller bearings from FTM can also include seals to prevent contaminants from entering and to extend service life in harsh environments.
FTM’s custom crossed roller bearings thus ensure stable rotational accuracy and torque, providing dependable performance in demanding conditions.

Key Features of Custom Crossed Roller Bearings:
Integrated Design: The RU crossed roller bearing series includes mounting holes, eliminating the need for pressing flanges or housings, thus simplifying installation and reducing additional components.
High Rigidity and Precision: Known for their high rigidity and precise rotation, RU bearings can withstand large radial, axial, and moment loads, ensuring smooth rotation even under heavy loads and in space-constrained applications.
Uniform Load Distribution: The alternating cross-roller arrangement evenly distributes loads across the bearing, enhancing its lifespan and reliability.
Compact Size: The RU series saves space in machine tools.
Customizable Features: Crossed roller bearings can be tailored for size, precision, surface roughness, material, and surface treatment to seamlessly match machinery or robotic requirements, with sizes ranging from 10mm to 250mm.
Application Areas: RU crossed roller bearings are used in precision applications such as industrial robots, machine tools, medical equipment, and optical instruments, where high precision and load-bearing capacity are critical.
