High-Load Linear Ball Bearings
Designed to handle heavy loads, these bearings have higher load capacities than comparable standard linear ball bearings. They are for use with round end-supported shafts and have a self-aligning design to compensate for shaft misalignment. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).
Bearings with end seals keep lubricant in and dust out.
Bearing with stainless steel balls is more corrosion resistant than bearings with steel balls.

Linear Ball Bearings for Support Rail Shafts
Mount these bearings on a support rail shaft for applications requiring maximum rigidity. All have end seals to keep lubricant in and dirt out. To install, slide bearings into a housing (not included) and secure in place with two retaining rings (sold individually).
Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.
Self-aligning bearings compensate for shaft misalignment.
