Specification Brand : THEGRTCWS BulletPoint1 : Premium Quality:Our wheels are specially engineered to withstand harsh chemical environments and are resistant to greases, oils, brine, solvents. Our Polyurethane Wheels are completely non-marking, quiet to roll, and soft to roll over obstacles and debris with ease. BulletPoint2 : High Load Capacity:These casters were designed with strength and sturdiness in mind for a long lifespan and easy movement of large, heavy loads. Each caster holds up to a maximum of 350 lbs. or 1400 lbs when purchasing a set of 4 casters. BulletPoint3 : Precision Ball Bearings:These Wheels come with Precision Ball Bearings which is a huge upgrade from most wheels with a plain bore. Precision Bearings help the caster roll easier and quieter while providing a very smooth ride. BulletPoint4 : Upgraded Casters:We've also upgraded these with small thread guards to protect the bearings from dust, debris, hair, and threads from accumulating between the axle and bearing to allow these casters and wheels a much longer lifespan than the competition. These wheels perform great on floors that contain metal shavings, gravel, dirt, and/or debris. BulletPoint5 : Widely Used:These wheels are commonly seen on high-end furniture dollies, carts, dolly cart casters, food service cart casters, material handling cart casters, maintenance cart casters, stocking cart casters, clean room cart casters, computer cart casters, laboratory cart casters, medical cart casters, computer rack casters, and many institutional cart casters.
