About Copper, Brass, and Bronze

Angle Rails for V-Groove Track Rollers

Use these rails with any track rollers that have a 90° V-groove.

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.

Corrosion-Resistant 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 Corrosion-Resistant Ball Screws and Nuts

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

Acme Lead Screws and Nuts

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.

Ball Transfer Plates

These plates are designed to rest on a flat surface and are good for rotating and positioning heavy workpieces.

Covers for Ball Transfer Plates

Covers create a smooth surface so small and oddly shaped items won't get caught between ball transfers.

Raw Materials

Corrosion-Resistant 316 Stainless Steel

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Tight-Tolerance 932 Bearing Bronze Bars

Precision ground on the top and bottom, these bars have a tight thickness tolerance of ±0.002".

Oversized Weldable 954 Bearing Bronze Bars

Thickness and width are oversized to allow for finishing.

Tight-Tolerance Weldable 954 Bearing Bronze Bars

These bars are precision ground on the top and bottom for a tight thickness tolerance of ±0.002".

MDS-Filled Easy-to-Machine
Wear-Resistant Cast Nylon Tubes

The addition of MDS gives these tubes exceptional wear resistance along with a self-lubricating surface. They're made of cast nylon 6, making them easier to machine and better electrical insulators than other MDS-filled nylon tubes.

Heat-Stabilized Easy-to-Machine
Wear-Resistant Cast Nylon Tubes

A good choice for making sprockets and pulleys, these cast nylon 6 tubes withstand higher temperatures and are easier to machine than standard nylon 6/6 tubes.

Clear Impact-Resistant Polycarbonate Tubes

At only half the weight of glass, polycarbonate maintains excellent impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.
