Maintenance Free Casters

Our line of maintenance-free casters is designed to reduce the force exerted to turn or start rolling when all caster wheels are not parallel. They feature neoprene-sealed precision ball bearings and hardened raceways, providing smooth swivel rotation with less effort.

These sealed precision ball bearings are pumped with grease and sealed on each side of the ball raceway. The seals lock in grease and prevent dirt or liquid from entering. This attribute extends the caster’s life in the toughest of industrial environments.

Maintenance-free casters do away with the need to grease fittings twice or more each year, but they do not entirely negate the need for inspections and maintenance. Every caster in your facility should be inspected monthly to ensure safety and productivity. Any repairs or replacements should be made immediately to help prevent possible injuries or damage to the loads they support.

Features and benefits of Caster Concepts’ Maintenance Free Casters include:

  • Maintenance free (no nut that needs to be re-tightened on the kingpinless swivel section)
  • Accommodates high-speed/high-capacity applications
  • Wheels available in 4, 6, 8, 10, 12, and up to 28-inch diameters
  • Casters swivel faster with less resistance
  • Keeps dirt, dust, and other debris from getting into the caster
  • Precision ball bearings roll easier — great for AGVs and continuous-use applications



Maintenance-free casters are found in applications where companies are looking for reducing exertion, maximizing safety, and increasing performance. These casters also excel in continuous-use applications when stoppage and downtime are outside the normal function.

Caster Concepts has a wide variety of caster options. Many of these not only improve function – but also provide safety and add longevity to the product. When considering safety options, the most common consideration would be caster locks, caster brakes, toe guards, and reinforced legs. Options that extend the life of a caster are primarily options that seal the bearing of the caster to prevent contamination of the precision parts.

Other options include threaded zerks for when an application is difficult and high level of maintenance is required and track brush wipers that keep debris from stopping movement or damaging a wheel. These options can be added at the time of manufacturing or after the caster is fully assembled.
