High-Load Linear Ball Bearings for Support Rail Shafts
Without Retaining Ring Grooves
With Retaining Ring Grooves
Designed for heavy loads, these bearings have higher load capacities than comparable standard linear ball bearings for support rails. Use them for applications that require maximum rigidity. All are self-aligning to compensate for shaft misalignment. 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 lubricants in and dirt out.
Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.
