K 265X280X50-Needle roller bearing-FGFA bearings

K 265X280X50 Single row needle roller and cage assembly

Needle roller bearings are compact transmission components utilising slender needle rollers as rolling elements. Their core advantages lie in their small size and high radial load capacity – within equivalent installation space, they far exceed the load-bearing capacity of standard ball bearings while offering a compact structure that significantly reduces equipment footprint. Suitable for medium-to-low speed applications, they exhibit impact resistance, stable transmission efficiency, and facilitate straightforward installation and maintenance.
