McMaster-Carr

Offering excellent antifriction qualities, 932 bronze also offers good strength and wear resistance. It's also known as SAE 660 and is often used for bearings, bushings, and thrust washers.

Oil-Filled 841 Bearing Bronze Tubes

Powdered bronze is pressed and then impregnated with SAE 30 oil to make this material self-lubricating.

High-Temperature Graphite-Filled
841 Bearing Bronze Tubes

An excellent alternative to oil-filled bronze, graphite-filled bronze provides dry lubrication in temperatures as high as 700° F.

Easy-to-Machine 936
Bearing Bronze Tubes

An easier-to-machine alternative to 932 bronze, 936 also has better corrosion resistance. It's also called modified SAE 64.

Weldable 954 Bearing Bronze Tubes

954 bronze contains a minimum of 10% aluminum for strength and weldability. It is also known as aluminum bronze. It's widely used for bearings, bushings, valve bodies, and worm gears. The strength of this material increases with heat treating.

High-Strength 863
Bearing Bronze Tubes

Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated.

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.

Easy-to-Weld 4130
Alloy Steel Round Tubes

4130 alloy steel has a low carbon content that provides good weldability. It's often used for gears, fasteners, and structural applications.

Easy-to-Weld 4130 Alloy Steel
Round Tubes with Certification

All come with a traceable lot number and test report.

Low-Carbon Steel Balls

Also known as mild steel, use these low-carbon steel balls in parts that don't require high strength.

Tight-Tolerance Hardened
440C Stainless Steel

With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance.

Hardened Shock-Resistant
S2 Tool Steel

This S2 tool steel has been hardened for excellent strength and impact resistance. It has a tough core that resists breaking under shock loads.

High-Temperature
High-Speed M50 Tool Steel

This hardened M50 tool steel maintains its strength and wear resistance even when temperatures rise. It is widely used for bearings.

Multipurpose Plastic

Wear-Resistant Nylon Tubes

Also known as nylon 6/6, this general purpose material is often used for bearings, gears, valve seats, and other high-wear parts.

Easy-to-Machine Wear-Resistant
Cast Nylon Tubes

This cast nylon 6 material is easier to machine than other types of nylon. It’s comparable to Nylatron and Nycast.

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

This nylon stays lubricated over time because it’s filled with oil. Use it to fabricate parts for hard-to-reach places where adding lubricants would be difficult.

Wear-Resistant Easy-to-Machine
Delrin® Acetal Resin Tubes

Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Slippery UHMW Polyethylene Tubes

In addition to a low-friction surface that prevents sticking and binding, this tough material is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.
