High-Temperature Linear Ball Bearings for Support Rail Shafts
The choice for low-friction motion in high-temperature environments. Mount these bearings on a support rail shaft for applications requiring maximum rigidity. They have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure in place with two retaining rings (sold separately).
