Needle-Roller Thrust Bearings
 |  |
Bearings | Washers |
Small but mighty, our thinnest rolling thrust bearings slot into tight spaces and spin at whirring speeds. Their long, slender rollers support thrust loads and reduce friction in everything from machine tool spindles to gearboxes.
A cage holds the rollers in place. You can install these bearings without washers between hardened, ground surfaces for the thinnest profile. If you’re working with unhardened, unground surfaces, you’ll need two washers for the rollers to run on. This three-piece design is easy to lubricate, but the oil will attract dust and grime since it’s exposed.
Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

Rotary and Linear Ball Bearings
 |  |
Fixed Alignment Without End Seals |
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.

Oil-Embedded 841 Bearing Bronze Round Tubes
 |
With a porous surface that releases oil over time, this bronze lubricates itself. Turn it into parts that you can't easily access to relubricate, such as bearings, well pumps, and turbine blades. The oil may burn away if temperatures climb too high, however. For extreme heat up to 700° F, consider graphite-embedded bearing bronze instead.

Multipurpose 932 Bearing Bronze Round Tubes
 |
Balancing strength, corrosion resistance, and machinability, 932 is everything you want in a bearing bronze. It's most commonly made into thrust bearings and bushings. Also known as SAE 660.

Press-Fit Drill Bushings
 |  |
Also known as jig bushings, these drill bushings fit inside fixture plate holes to precisely guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so your drilled holes and cuts are consistent from part to part. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings.
Press into place with a manual or hydraulic press. Since these bushings are sized slightly larger than the hole for an extremely tight fit, they’ll stay put permanently. These are ANSI Type P bushings—also known as headless bushings—which means you don’t need to counterbore the hole to mount them flush.

Telescoping UHMW Polyethylene Round Tubes
 |
Telescoping 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. 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.

Clear Scratch- and UV-Resistant Acrylic Round Tubes
 |
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.

Corrosion-Resistant 954 Bearing Bronze Round Tubes
|
One of the most corrosion-resistant bearing bronze alloys, 954 withstands everything from sea water to sulfuric acid. It's often turned into bearings and valve bodies for demanding environments such as salt mines. Also known as aluminum bronze. If you need similar corrosion resistance with even greater strength, consider 955 bearing bronze instead.

Highly Machinable 936 Bearing Bronze Round Tubes
|
With almost twice as much lead, 936 bearing bronze machines more easily than 932. It's often made into bearings and bushings for oil pumps and gasoline engines. Also known as modified SAE 64.
