Overview

The 77 Series Caster utilizes a dual (sealed precision) bearing design, enabling smooth and easy rotation with a maximum capacity of up to 3,500lbs per caster. This caster series is the first in the Maintenance Free line to support 3″ wide wheels, up to a 10″ diameter. When coupled with TWERGO® 3″ wide wheels, this caster provides excellent ergonomic performance, even with a wider wheel. The dual bearings also help reduce push force when starting the cart rolling, while the wheels are not all parallel.

Applications

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.

Options

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.
