Bunting Bearings EXEF050806 Extra Lubricant with PTFE Flange Bearing, Powdered Metal, SAE 841, 5/16" Bore x 1/2" OD x 3/8" Length 11/16" Flange OD x 1/16" Flange Thickness (Pack of 3);

For stop, start and slow speed applications 841 EXTRA is the recommended choice. These bearings contain SAE 30 oil with a finely dispersed PTFE. The PTFE in the oil greatly reduces friction and helps to develop a full lubrication film which is especially required on start up. A smoother and quieter operation, an easier “break-in” period and longer life can be achieved.
