How Bearings Can be Useful?

A bearing is a component that constricts motion, thus reducing friction and handling any stress between moving parts. Bearings are used in a wide range of applications including: automobiles, airplanes, machine tools, DVD players, household appliances and more. Here are some commonly used bearings:

Sealed Precision Ball Bearings

  • Recommended for maximum rolling ease
  • Require no maintenance lubrication
  • Quiet operation
  • For medium to heavy duty loads
  • Can be for radial and thrust loads

Annular Ball Bearings

  • Provide full-length support across width of wheel
  • Quiet operation
  • For light to medium loads (up to 1200lbs per wheel)
  • Side thrust load approx. 20% of radial capacity

Flanged Ball Bearings

  • Unique design eliminates bearing and wheel seizing
  • Constructed of hardened bearing quality steel
  • Pre-greased

Caged Roller Bearing

  • High radial capacity
  • Long-wearing precision inner race
  • Some do not require usage of spanner bushings

Roller Bearings

  • Consist of a cage roller assembly and a split outer race
  • High radial capacity
  • Minimal side thrust load rating

Precision Tapered Roller Bearings

  • Designed for heavy loads and high-speed operation
  • Side thrust load rating of 60-90% radial capacity
  • Two bearings needed per wheel

Delrin Bearings

  • Durable in a wide range of temperature conditions
  • Corrosion resistant – suitable in situations where liquids are present
  • Light oil or lubrication recommended

Plastic Sleeve (Celcon) Bearings

  • Made for environments not suitable for metal bearings
  • Chemical and corrosion resistant – also suitable in situations where liquids are present
  • Light oil or lubrication recommended
  • Available in flanged or sleeve bearings

Oilite Bearings

  • Inexpensive
  • Highly efficient
  • Press-fit to wheel bore
  • Come with a “lifetime lubrication” under normal usage

Plain Bore

  • Used for light loads
  • Bore is directly on spanner bushing or caster axle, meaning ease of rolling is low
