Full Pneumatic (SF) Recommended for the greatest possible protection to both loads and floors. If you transport fragile materials or parts, or if you move delicate instruments over rough floors, you should consider a pneumatic tire. Full pneumatics cushion the load on air, just like an automobile. They must be properly inflated as indicated in wheel table. Can be filled with urethane foam to make them deflation proof, but foam has no effect on capacity. Suitable for extended service.
New Gray Pneumatic Tires:Feature non-marking floor protection. Full pneumatics cushion the load on air, just like an automobile tire. Smoother ride over rough floors. Load capacities up to 350 lbs. per tire. Wheels can be filled with urethane foam to make them deflation proof, but foam has no effect on capacity.
Looks and performs similar to pneumatic wheels, but without the hassles of air pressure maintenance and flat tire repair. Also reduces maintenance time and expense. Closed cell expanded foam construction resists water absorption (unlike others currently in the marketplace).
Radial sawtooth tread for easy maneuverability and traction (radial tread on 8" model).
Quiet, smooth operation.
Non-marking for superior floor protection.
Rolls over obstacles with ease and absorbs shock to protect cargo.
The SZ (black) and SV (gray) wheels provide you with all the benefits of a pneumatic tire, without the hassle of getting a flat. These maintenance-free wheels, constructed of solid. monoprene material, which rejects debris and will not go flat, offer the same great features of a pneumatic wheel.
