Hard Wear-Resistant 52100 Alloy Steel

Hard Wear-Resistant 52100 Alloy Steel Rods

Also known as chrome steel, 52100 is an extremely hard and wear-resistant material. It’s used for parts such as bearings, bushings, and punches.

Hard Wear-Resistant 52100 Alloy Steel Balls

Also known as chrome steel, 52100 is an extremely hard and wear-resistant material. These balls are often used in bearings.

Tight-Tolerance Hard Wear-Resistant
52100 Alloy Steel Balls

The diameter on these balls is held to a precise tolerance.

Hard Wear-Resistant 52100 Alloy Steel Tubes

Easier to machine than 52100 alloy steel rods, these extremely hard and wear-resistant tubes are often used to create bearings, bushings, and other cylindrical parts that are under constant stress. They’re also known as chrome steel.

Hard Wear-Resistant 52100 Alloy Steel Wire

Also known as chrome steel, 52100 is an extremely hard and wear-resistant material. This wire is often used for small-diameter bearings, bushings, and punches.

Shafts

Linear Motion Shafts

Combine these general purpose shafts with a linear bearing and shaft support to create a basic linear motion system.

Hollow Linear Motion Shafts

Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.

Tapped Linear Motion Shafts

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

Threaded Linear Motion Shafts

Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory.

Ball Splines and Bearings

Create a compact linear and rotary motion system for applications requiring complex, fast movements, such as robotics.
