Linear Ball Bearings
Bearings are for use with round end-supported shafts. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually). Bearings with end seals keep lubricant in and dust out. Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls. Self-aligning bearings compensate for shaft misalignment. Fixed-alignment bearings are for use where shaft misalignment is unlikely.
