Spyraflo Needle-Roller Bearings combine an extremely compact, high performance, rolling element bearing with our patented mounting technology. These bearings offer the broadest range of performance and are ideal for slow to high speeds with light to high loads.

To save cost, space and assembly time, these bearings do not have inner races. A hardened shaft will perform the function of the inner race. The shaft may be through hardened or case hardened with a minimum case depth of .040” [1mm]. The bearings can arrive pre-lubricated with high quality lithium complex grease.
