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.

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.

Tapped Rotary Shafts

Directly connect threaded components to these internally threaded shafts, or secure fan blades and other accessories with a fastener. Turned, ground, and polished to tight tolerances, they evenly distribute loads, reduce vibration, and improve accuracy.

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

Build-Your-Own Support-Rail Shafts

Choose a shaft and a matching support rail in the profile you need to create a custom setup for your machine’s layout. Tapped holes drilled along the length of these shafts match up with holes on support rails for quick alignment and setup. The support rails prevent bending and bearing misalignment under moderate to heavy loads. 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.

Cut the support rails and shafts to size or mount them end-to-end for long runs. Then, align the mounting holes on the shafts with those on the rails and fasten them with socket head screws (not included). After assembly, test for alignment to guarantee smooth motion.

Shafts

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.

Support-Rail Shafts

Attached support rails prevent bending or bearing misalignment under moderate to heavy loads. Pair with linear bearings to create smooth, precise motion. These linear shafts are turned, ground, and polished to tight tolerances and hardened to resist wear.

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.

Lightweight Ceramic-Coated Aluminum—Lightweight and corrosion resistant with an ultra-hard, slippery ceramic coating for wear resistance. Even contaminants such as weld spatter, molten glass, and paint won't stick to these shafts. While the coating is hard, they have a soft core, so they should be used with linear sleeve bearings to avoid denting the shaft.

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