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.

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.

Multipurpose Thrust Bearings
These 660 leaded bronze bearings are strong, wear resistant, and excellent at handling shock loads. They’re sometimes called 932 bronze 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.

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.

Clamping Acme Lead Screw Collars
Thread these one-piece collars onto an Acme lead screw to separate and position components, or use them as an end stop to limit travel. Tighten the clamping screw to secure.
To ensure compatibility, please select a collar that has the same thread type, direction, and size as your lead screw.
Black-oxide carbon steel collars have mild corrosion resistance.

Wide-Rim Ring Shims
Also known as machinery bushings, these shims have an oversized OD to create a larger bearing surface for reduced wear between moving parts. Use them to precisely align, level, and adjust spacing on shafts and machinery.
Carbon steel shims have excellent strength and can be welded.
A zinc-plated finish adds a layer of corrosion resistance.

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.
