Description

Listing is for a set of four (4) Service Caster Series #30 stainless steel swivel casters with 4" diameter by 2" wide thermoplastic rubber donut tread wheels with top lock brakes capable of supporting a total weight of 1,200 lbs. (300 lbs. per caster). When searching for a reliable and durable solution for medium and heavy duty projects, consider Service Caster’s Series 30 stainless steel thermoplastic rubber donut tread on polyolefin core casters. The rounded face "donut" style soft tread is made of thermoplastic rubber that is non-marking, non-marring and provides easier mobility over standard flat tread wheels, resulting in a long lasting, high capacity wheel capable of easy rolling under heavy loads. Finely crafted with double ball bearing heat treated raceways, these versatile casters are ideal for a wide range of applications, such as dollies, platform trucks, warehouse carts and freight terminals. Or ensure a smooth and secure ride for food service carts, hotel housekeeping carts, and industrial and commercial equipment. Even drywall carts, welding carts, and wall panel carts will be ready to roll on the Series 30, keeping you moving forward. In contrast to the zinc plated caster, the luxuriously polished stainless steel finish resists rust and corrosion in indoor or outdoor applications where moisture is a factor. Service Caster is unsurpassed in quality, reliability, and excellent customer service. Count on us to move you forward. • These Service Caster Series #30 Thermoplastic Rubber Donut Tread on Polyolefin Core 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: 4": 300 lbs Capacity/Caster, 5": 350 lbs Capacity/Caster, 6": 500 lbs. Capacity/Caster, and 8": 600 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 top lock brake (TLB) and a total lock brake (TTL). The top lock brake (TLB) places a positive locking force against the wheel tread locking the wheel only. The total lock brake (TTL) also places a positive locking force against the wheel tread, but the total lock brake (TTL) simultaneously locks the wheel and the swivel for a complete stationary position.
