5 Inch Thermoplastic Caster Set with Roller Bearing 4 Brake and 2 Swivel Lock

These Service Caster Series #35 Thermoplastic Rubber Donut Tread casters offer various wheel sizes and mounting heights: 4” Wheel: 5-5/8” mounting height; 5” wheel: 6-1/2” mounting height; 6” wheel: 7-1/2” mounting height; 8" wheel: 9-1/2" mounting height. Weight capacity ranges from 300 lbs on the 4” caster, 350 lbs on the 5”, 500 lbs on the 6” and 600 lbs. on the 8”.

Top plate measures at 4-1/2" x 6-1/4" with a bolt hole pattern of 2-7/16" x 4-15/16" to 3-3/8" x 5-1/4" 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.
