Medium—Medium wheels are shock absorbing.

Hard—Hard wheels are impact resistant.

2 Wheels—Dual-wheel casters provide better load distribution and easier turning than single-wheel casters.

Without Bearing—Casters without wheel bearings have a wheel that rides directly on the axle, making them an economical choice for equipment not frequently moved.

Shielded Bearing—Shielded bearings protect from dust and debris.

Dual-Raceway Bearing—Swivel casters with dual-raceway bearings have the smoothest swiveling.

Sealed Bearing—Sealed bearings are completely sealed for the best protection against dust and debris.

Washdown Recessed Flange-Mount Ball Transfers

With a ball recessed into the mounting surface, these ball transfers have a low profile. Their double-sealed ball keeps out dirt and debris, and side vents expel contaminants. Because their ball is stainless steel, they resist corrosion. They also don’t need to be lubricated. If you orient them at an angle, you can use them to build support stands.

Weight capacity is given for the ball up orientation. Using these ball transfers in a ball down or angled orientation could reduce the weight capacity stated.
