Bearing Retaining Locknuts

With a nylon insert that grips your threaded shaft or spindle without damaging its threads, these locknuts—also called shaft nuts—hold bearings, bushings, gears, and pulleys prone to vibration tightly in place.

Bearing Retaining Nuts

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.

Bearing Retaining Jam Nuts

Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle.

Metric Ball Screws and Nuts

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start metric ball screws and nuts, these have a single thread that runs the length of the screw.

Ball Screws and Nuts

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts.

Fast-Travel Ball Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start.

Self-Stopping Ball Screws and Nuts

Keep your ball screw spinning without the ball nut damaging your system. When the ball nut reaches the stop pin at either end of the ball screw, it disengages and begins to idle.
