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). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).
Fixed Alignment—Fixed-alignment bearings are for use where shaft misalignment is unlikely.
Stainless Steel Ball—Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.
