Hub-Mount Screw-Clamp Bushings
Transfer torque directly from a shaft to a hub. These bushings install over your hub to mount a sprocket, pulley, or gear to a shaft at the same time. Common in industrial gearbox applications, they can also connect a hollow shaft over a solid shaft. As screw-clamp bushings, they're good for shock loads. When you tighten the included clamping screws, the outer rings compress against a sprocket, pulley, or gear in between them, causing the inner rings to tighten around the shaft.

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.

Bearing Caps
Cover standard or flange-mount bearings to protect personnel from injury and keep contaminants out. Place caps over the entire bearing housing and drill holes in their flange to install with screws. If necessary, drill the caps for access to bearing grease fittings or to create space for a shaft to pass through, and trim the flange to fit in tight spaces.
Black ABS caps resist UV light, so they won’t color or crack when exposed to the sun.
