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.
Variation of the top plate size is available. If you are looking for the greatest ergonomic improvement and willing to give some carrying capacity, look at a optional change in the lead to achieve this. Once you have the lead that works in your application, find the wheel with a sealed bearing that will minimize rolling resistance and add to the ergonomic design that you need.
