The 57 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 the functional life of the swivel section. No greasing is necessary. The smooth swivel action combined with the extended lead help to lower ergonomic forces and minimize employee injuries.
Excellent for production racks (power transported, manually handled and mobile fixtures), parts bins, conveyor system, and other applications where maintenance free casters and ergonomics are concerns.
Variations in top plate size are 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.
