Frequently Asked Questions (FAQs)
How does XSU080258 compare with other crossed roller bearing models?
The XSU080258 offers a larger bore size (220 mm) compared to smaller models such as XSU080218, making it suitable for heavier loads and larger rotary mechanisms. If space is limited but high stiffness is still required, a smaller series may be more cost-effective.
Can XSU080258 be customized?
Yes. Depending on customer requirements, retainer type, lubrication method, seal configuration, and material selection can be customized. Custom preload adjustments are also available to meet specific rigidity or clearance requirements.
Is XSU080258 suitable for high-speed rotation?
XSU080258 is mainly designed for high-precision positioning and medium-speed operation. For applications requiring very high rotational speed, a different bearing type such as angular contact ball bearings may be more appropriate.
How long is the expected service life of XSU080258?
Service life depends on load conditions, lubrication, operating speed, and maintenance. Under proper use with regular lubrication, XSU080258 can provide a long operational lifespan, even in demanding industrial environments.
How is the XSU080258 lubricated?
The bearing is typically grease-lubricated and comes with lubrication holes for easy maintenance. Proper lubrication ensures smooth operation, reduces wear, and extends service life.
Why choose XSU080258 instead of a conventional bearing?
Unlike standard bearings, the crossed roller design of XSU080258 can simultaneously carry loads in multiple directions, which reduces the need for paired bearings. Its integrated structure also saves space and simplifies installation, making it highly efficient for precision systems.
