YRTC 260XL Bearing Parameters and Applications
1、 Basic parameters
Size specifications
Inner diameter (d): 260 mm 57
Outer diameter (D): 325 mm 5
Height (H): 55 mm 57
Weight: Approximately 18.3 kg (refer to YRT260 model in the same series)
Performance parameters
Design feature: Cross roller structure, capable of withstanding radial force, bidirectional axial force, and overturning moment simultaneously
Sealing option: Supports double-sided sealing design (if the model includes a sealing suffix)
2、 Structural characteristics
Cross roller layout
Cylindrical rollers are arranged in a vertical cross pattern to enhance rigidity and load-bearing capacity, suitable for high-precision rotary systems
Integrated or separated outer/inner ring design, easy to install and maintain
Optimize design
The XL suffix may indicate lightweighting or material strengthening (such as X-life technology) to increase the rated lifespan
Some models support integrated angle measurement systems (similar to the YRTM series)
3、 Typical applications
High precision machinery
Machine tool turntable: a rotating worktable used for precision machining centers to ensure high repeatability positioning accuracy
Automation equipment: robot joints, rotating units of industrial robotic arms
Overloading scenes
Aerospace equipment: satellite antenna brackets, radar turntables, and other scenarios that require high stability
Measuring instruments: optical instrument turntable, high-precision detection equipment
4、 Adaptation instructions
Alternative models: interchangeable with YRT260 series of the same size, but attention should be paid to differences in sealing and precision levels
Installation requirements: Pre tightened bolts and precise adjustments are required to ensure a rotation accuracy of ≤ 0.001 mm
