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.

One-Piece Thrust Ball Bearings
In addition to handling higher loads than three-piece ball bearings, one-piece bearings are easier to handle. They have an outer band that holds the bearing together and acts as a shield against dust and other contaminants.

Oil-Embedded Thrust Bearings
Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Mounted Roller Bearings
Roller bearings have a thinner profile and larger contact area than ball bearings, making them stronger and more space-efficient than ball bearings.
Sealed bearings block out dust and contaminants.

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.

- 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.
