Ultra-Thin Ball Bearings
These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.
Open bearings dissipate heat more efficiently than shielded bearings.

932 Bearing Bronze Tubes
- Yield Strength: 18,000 psi
- Hardness: Rockwell B35 (Soft)
- Temper: M07
- Heat Treatable: No
- Specifications Met: ASTM B505
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
- Yield Strength: 11,000 psi
- Hardness: Not Rated
- Temper: Not Rated
- Heat Treatable: No
- Specifications Met: ASTM B438
Powdered bronze is pressed and then impregnated with SAE 30 oil to make this material self-lubricating. Use it to make bearings and parts for hard-to-reach areas that would be difficult to access for lubrication, such as well pumps and turbine blades. These tubes are oversized on the outside and undersized on the inside to allow for finishing to the sizes listed.

Weldable 954 Bearing Bronze Tubes
- Yield Strength: 32,000 psi
- Hardness: Rockwell B85 (Medium)
- Temper: M07
- Heat Treatable: Yes
- Specifications Met: ASTM B505
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.
