Bearing Spring Lock Washers for Slotted Bearing Nuts
 |  |
For Chamfered Nuts |
Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle. They also have an inner tab that sits in the shaft or spindle’s keyway to prevent the nut from loosening.
Steel—Steel washers are strong and flexible.
Stainless Steel—Stainless steel washers are more corrosion and chemical resistant than steel washers.
External Tooth—Washers with external teeth grip components using their teeth, in addition to spring tension.
