Bearings and bushings support rotating and sliding shafts in motors, conveyors, pumps, fans and carts. This subcategory includes deep groove ball bearings, tapered and cylindrical roller bearings, needle bearings, mounted bearings in pillow block and flange housings, sintered bronze (oil-impregnated) bushings, plain bronze bushings, flanged bushings, plastic bushings and thrust washers. Sizes are offered in inch and metric.

What to check before you order

  • Bearing number. Most ball bearings carry a standard number. In 6205-2RS, for example, 05 means a 25 mm bore and 2RS means rubber seals on both sides. ZZ means metal shields.
  • Seals or shields. Sealed bearings keep out more dirt and moisture. Shielded bearings have less drag and suit cleaner, faster applications.
  • Mounted bearing details. For pillow blocks and flange units, match the shaft size, bolt hole spacing, housing material and locking style, such as set screw or eccentric collar.
  • Bushing dimensions. Measure inside diameter, outside diameter and length. Oil-impregnated bronze suits light loads where relubrication is hard.

Use proper pullers and presses for removal and installation, following the manufacturer's instructions. Grease is in grease and anti-seize, shaft seals are in seals, O-rings and gaskets, and the full category is power transmission. For a bearing number you cannot find, send a quote request.

Common questions

How do I find a bearing size if the number is worn off?

Measure the bore, outside diameter and width with calipers, in both millimeters and inches. Compare those dimensions to a bearing size chart, and note whether it has seals or shields, to find the matching number.

What does C3 mean on a bearing?

C3 means the bearing has more internal radial clearance than a standard bearing. It is often used where heat or a tight fit expands the inner ring, such as in many electric motors. Replace a C3 bearing with another C3 unless the equipment maker says otherwise.
