Threaded Linear Shafts

Screw the end of these shafts into a tapped hole, eliminating the need to mount them with additional shaft supports. You can also attach a nut to mount them. Pair these shafts with linear bearings to create smooth, precise motion. They are turned, ground, and polished to tight tolerances and hardened to resist wear.

Threaded on One End

Steel—Stronger than aluminum and stainless steel. These shafts are best for dry environments since moisture will cause them to rust.

Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.

Tapped Linear Shafts

Mount directly with studs, bolts, and other threaded fasteners—no shaft supports needed. Pair with linear bearings to create smooth, precise motion. These shafts are turned, ground, and polished to tight tolerances and hardened to resist wear.

Tapped on One End

Steel—Stronger than aluminum and stainless steel. These shafts are best for dry environments since moisture will cause them to rust.

Highly Wear-Resistant 440C Stainless Steel—Balancing strength, wear resistance, and corrosion resistance, these shafts can handle moisture and mild cleaning solutions.

Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.

Threaded Rotary Shafts

Screw these shafts directly into tapped holes, or secure fan blades and other accessories with a nut. Turned, ground, and polished to tight tolerances, these shafts reduce vibration, evenly distribute loads, and improve accuracy.

Carbon Steel—Strong and easy to machine. These shafts work best in dry environments since moisture will cause steel to rust.

Tapped D-Profile Rotary Shafts

Directly attach accessories and securely mount power-transmission components. These shafts have threaded ends to connect fan blades, mixer propellers, and other accessories with a fastener. The flat length mates with D-shaped bores and gives set screws an even surface to dig into, so gears, bearings, and sprockets won’t slip as the shaft rotates. Turned, ground, and polished, these shafts reduce vibration, evenly distribute loads, and improve accuracy.

Carbon Steel—Strong and easy to machine. These shafts work best in dry environments since moisture will cause steel to rust.
