Hart Design 3" Swivel Spindle Caster
If you have limited shop space, or just have a lot of materials to move around, then just imagine the tremendous flexibility and convenience you'll get by putting cabinets, carts, tools, and work stations on wheels.
Urethane tires resist flattening and have excellent resistance to corrosion and wear. Roller bearing axles ensure smooth rolling and long life, while the hub shields give the bearings additional protection from dust and dirt contaminants. At nearly 1-1/4" across, the metal wheel housings on these casters are big, thick, and sturdy.
Spindle Casters are best used on open stands or work tables where plate mounted casters would be impractical to attach. Swivel posts have an M12 (12mm - approx. 1/2") X 1.75 pitch/thread and are 1" long. An M12 nut is included with each caster. Brake mechanism locks both the swivel and the wheel.
3" casters are 4-1/4" tall from the floor to the top of the plate and have a load capacity of 220 lbs.
