55 Series Caster


The 55 Series provides the ultimate maintenance free combination. The swivel section is made from a high quality precision ball bearing. The raceways of the bearing are hardened for long life and the bearing is then sealed with neoprene seals to assure protection from contamination. No greasing is necessary. The smooth swivel action combined with an extended lead, help to lower ergonomic forces and minimize employee injuries.


Excellent for production racks power transported and manually handled, mobile fixtures, parts bins, conveyer systems, and other applications where maintenance free casters and ergonomics are concerns.

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.
