6 Inch Dual Pneumatic Wheels Swivel Caster Set with Ball Bearings SCC

The Series 100 pneumatic casters come in 6” (mounting height 7.5”) and are made of pneumatic tread and an inner core filled with pressurized air which remains inflated even with the weight of a vehicle resting on it. Weight Capacity: 6": 250 lbs. Capacity/Caster Top plate measures at 4" x 4-1/2" with a bolt hole pattern of 2-5/8" x 3-5/8" to 3" x 3" and can either be bolted or welded on. Brake options include a side lock brake (SLB) which applies a positive locking force against the wheel hub which prevents the wheel from moving freely, or a bolt-on swivel lock (BSL) that when inserted into one of 4 notches found on the swivel raceway converts a swivel caster to rigid for straight-line tracking at any 90 degree angle. Combining both brake types ensures complete immobility over both swivel and wheel on the caster.
