Base-Mounted Shaft Supports
For use with light to medium loads where shaft alignment is not critical, these shaft supports brace the end of a linear shaft along the ground or other flat surface. They are T-shaped, so the mounting flanges are on the side. Mount the support to a surface from either the top or bottom using the unthreaded holes. Slide the shaft in to install, then tighten the included clamping screw to secure the shaft.
Iron shaft supports are heavier than aluminum shaft supports for a more stable mount.

Oversized Easy-to-Machine Gray Cast Iron Rods and Discs
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- Specifications Met: ASTM A247
An oversized diameter allows for finishing to your exact requirements. Gray cast iron machines faster with less wear on cutting tools than most types of steel. It also absorbs vibration, so finished parts run quieter than those made of steel. It's often used for gears, pulleys, rollers, and bushings.

Easy-to-Machine Impact-Resistant Ductile Cast Iron Rods
- Yield Strength: 45,000 psi
- Hardness: Rockwell C10 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- Specifications Met: ASTM A536
With a high amount of ferrite, these cast iron rods are easier to machine without cracking than other impact-resistant ductile cast iron rods. Use them to create bushings, gears, pulleys, and pistons. These rods are also known as 65-45-12 ductile iron rods. All conduct electricity. They will become magnetic if exposed to a magnetic field. They’re often used to replace low and medium carbon steel rods.

Precision Acme Lead Screws and Nuts
Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.
Cast iron nuts have good machinability and high strength.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Fast-Travel Precision Acme Lead Screws and Nuts
Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. The threads have a tight thread fit for accurate, repeatable starts and stops. Pair with a motor in automated motion and positioning applications. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.
Cast iron nuts have good machinability and high strength.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

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. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.
Cast iron components have good machinability and high strength.
Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.
