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.

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.

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.

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.

Clear Scratch- and UV-Resistant Acrylic Tubes
- Color: Clear
- Temperature Range: -40° to 180° F
- Tensile Strength; 9,195-11,030 (Good)
- Impact Strength: 0.040 ft.-lbs./in.
- Hardness: Rockwell M89-M96 (Hard)
- For Use Outdoors: Yes
- Specifications Met: UL 94 HB
When compared to cast acrylic tubes, these extruded acrylic tubes offer nearly the same performance at a fraction of the cost. Use them for sight gauges and protective covers. This scratch- and UV-resistant material stands up to outdoor use better than polycarbonate and maintains clarity over time.
