Needle-Roller Thrust Bearings
Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings. Because of the large contact area between the rollers and washers (not included), these bearings are great for medium to heavy duty, low-friction jobs. For use on hardened and ground surfaces.
Washers allow you to use the bearing on unhardened and unground surfaces.

Linear and Rotary Ball Bearings
Engineered for simultaneous linear and rotary motion, these bearings are used with round end-supported shafts. The fixed-alignment design is for use where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).
Bearings without a maximum stroke length are only limited by the length of shaft they're used on.

932 Bearing Bronze Tubes
- Yield Strength: 18,000 psi
- Hardness: Rockwell B35 (Soft)
- Temper: M07
- Heat Treatable: No
- Specifications Met: ASTM B505
Offering excellent antifriction qualities, 932 bronze also offers good strength and wear resistance. It's also known as SAE 660 and is often used for bearings, bushings, and thrust washers.

Certificates with a traceable lot number are available for these products. Download certificates from ACTIVITY after your order ships.
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.

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.

Slippery UHMW Polyethylene Tubes
These impact- and wear-resistant tubes offer 360° protection from scrapes and strikes to wires, cords, and anything that can slide through them. UHMW has a low-friction surface that resists sticking and binding.
Tight-tolerance tubes, also known as bushing stock, slide over rods and inside shafts to increase or decrease the diameter. Their precise sizing allows ascending sizes to fit inside each other to create a thicker wall.
