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.

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.
