4 1/2" ID Bearings | McMaster-Carr

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.

Easy-to-Machine 936 Bearing Bronze Tubes

Yield Strength: 21,000 psi
Hardness: Rockwell B25 (Soft)
Temper: M07
Heat Treatable: No
Specifications Met: ASTM B505

An easier-to-machine alternative to 932 bronze, 936 also has better corrosion resistance. It's also called modified SAE 64. Use it to machine bearings and bushings for oil pumps and gasoline engines.

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

Color: Black
Maximum Temperature: 230° F
Tensile Strength: 10,000 psi (Good)
Impact Strength: 1.4 ft.-lbs./in. (Poor)
Hardness: Rockwell R110 (Hard)
For Use Outdoors: Yes
Specifications Met: ASTM D5989

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. Tubes can be used to fabricate pulleys, bushings, and bearings installed in hard-to-reach areas where adding a lubricant would be difficult. The OD is oversized and the ID is undersized to allow for finishing to the sizes listed. This material is comparable to Nylatron and Nycast.

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

Color: Blue
Maximum Temperature: 250° F
Tensile Strength: 10,000-13,500 psi (Good)
Impact Strength: 1-2.5 ft.-lbs./in. (Poor)
Hardness: Rockwell R110-R120 (Hard)
For Use Outdoors: Yes

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. This material is comparable to Nylatron and Nycast.
