Electrical-Insulating Linear Sleeve Bearings
These fiberglass bearings are lightweight, nonmagnetic, and won’t conduct electricity. Bearings are for use with round end-supported shafts. All have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).
