RWM Casters SWB-0612-06 6" Diameter Tread Signature Wheel with Sealed Precision Ball Bearing, 300 lbs Capacity Range
The RWM Signature premium wheel has a lightweight, reinforced nylon core with a high strength non-marking elastomeric rubber tread. The round tread provides easy rolling. Our durable nylon core is six times stronger than polypropylene. The performance rubber tread is cut, tear and corrosion resistant and will not chunk out. It has the highest strength-to-weight ratio than any other wheel in the industry. The Signature premium wheel is excellent for floor protection, continuous towing and noise reduction. The RWM Signature premium wheel is ideal for platform trucks, material handling carts, warehouse and factory applications, food service, drywall carts and assembly line dollies.
Here's some basic mechanics... the rear end (aka differential) contains oil to lube all the gears. An axle shaft extends from the differential out to the end of the wheel to transfer the power (power goes from the engine, to the transmission, to the drive shaft, to the differential, to the axle shaft, and out to the wheels)....
Oil from the differential travels along the axle shaft out to wheel where it lubricates the wheel bearings. The oil is held within the wheel assembly on one side by the plate and gasket on the end of the axle shaft... and then held in on the other side by the wheel seal.
You can see in this picture the eight small studs that accept the axle shaft plate, and in the rear of the wheel, the rear set of the wheel bearings. Behind that set of wheel bearings is where the failed wheel seal would sit.

The GT wheel is a high performance wheel that combines the toughness of blended elastomers and quality steel with the advanced wheel design to carry heavy loads without component breakdown. It will resist most chemicals in industrial and institutional environments. The GT wheel will perform continuously for extended periods on all surfaces and under all conditions. This wheel provides excellent rollability with minimum effort. It will absorb impacts without damage that would shatter other wheels. The GT will perform under the most extreme temperatures almost entirely maintenance free, and will roll mile after mile with virtually no tread wear.
