Description

Listing is for a set of four (4) Service Caster Series #KP30 casters, two (2) swivel casters with bolt on swivel locks and two (2) rigid casters, with 8" diameter by 2" wide nylon wheels capable of supporting a total weight of 5,000 lbs. (1,250 lbs./caster). When searching for a reliable and durable heavy duty solution to your caster needs, consider Service Caster’s Series KP30 nylon wheel casters. The Service Caster Series #30 is ideal for medium and heavy duty material handling, carts, equipment, and shop projects. The zinc plated finish provides durability under any condition and the nylon wheels provide very low rolling resistance, show a high resistance to many aggressive substances and under normal operating conditions are maintenance free. Featuring a Kingpinless hot forged ASTM1045 steel design that increases caster durability and integrity, the series KP30 eliminates problems associated with kingpin failure due to severe shock loading. In addition, the Kingpinless design features 3/8” diameter HRC45 steel ball bearings which absorb thrust and load in severe environments. Lastly, Service Caster’s Series KP30 casters are finely crafted with grease fittings, and 4 position notches to accept 4-position locks. These highly versatile casters are ideal for a wide range of applications, such as dollies, platform trucks, warehouse carts and freight terminals. Even drywall carts, welding carts, and wall panel carts will be ready to roll on the Series KP30, keeping you moving forward. • These Service Caster Series #KP30 Nylon 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 800 lbs on the 4” caster, 900 lbs on the 5”, 1250 lbs on the 6” and 1250 lbs. on the 8”. • 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.
