Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Ball Screws and Nuts

Ball Screws and Nuts

Internal ball bearings roll on screws for low friction when moving components at high speeds

Ball Screw/Splines

Ball Screw/Splines

Transmit rotary power, move loads along the shaft, or do both at once

Roller Screws and Nuts

Roller Screws and Nuts

More contact points to move heavier loads than ball and lead screw assemblies

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Raw Materials

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Aluminum

Lightweight, easy to machine, and corrosion resistant in wet environments

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Brass

More machinable than copper and bronze for making nuts, hinges, and locks

Copper

The most conductive of our metals, it excels in all types of electrical applications

Bronze

With better wear resistance than copper and brass, it’s used for bearings, gears, and pump parts

Nickel

An upgrade from stainless steel that withstands harsh chemicals and acids at high temperatures

Tungsten

Our densest metal resists wear and heat to make end mills, heat shields, electrodes, and more
