Description

Listing is for one (1) Service Caster Series #20 1-1/2" expanding stem 316 stainless steel swivel caster with a 3-1/2" diameter by 1-1/4" wide solid polyurethane wheel and a top locking brake capable of supporting 300 lbs./caster. When searching for a reliable and durable solution to your caster needs, consider Service Caster's 316 stainless steel solid polyurethane wheel casters. Built with 316 stainless steel, which contains additional molybdenum and nickel content, makes this caster more corrosion resistant than standard 304 stainless steel. Molded as one solid piece, the non-marking, non-marring polyurethane wheel is free from debonding, and will not flatspot, as can occur with comparable polyurethane wheels, ensuring a smooth and solid roll over long periods of time. Mounting options include top plate, bolt hole, expanding stem and standard and metric threaded stem sizes. These versatile casters are ideal for a wide range of applications, such as dollies, platform trucks, warehouse carts and freight terminals. Or ensure a secure ride for food service carts, hotel housekeeping carts, and industrial and commercial equipment. • These Service Caster Series #20 Solid Polyurethane casters offer various wheel sizes and mounting heights: 3” Wheel: 4-1/8” mounting height; 3-1/2” wheel: 4-5/8” mounting height; 4” wheel: 5-1/8” mounting height; 5” wheel: 6-1/8” mounting height. • Weight Capacity: 3", 3.5", 4",and 5": 300 lbs Capacity/Caster • All casters feature an expanding stem that is 2-11/16” in length. The expanding stem comes in 10 different diameters: (3/4”, 7/8”, 1”, 1-1/8”, 1-1/4”, 1-3/8”, 1-1/2”, 1-5/8”, 1-3/4”, and 1-7/8”). Before ordering, Service Caster recommends measuring the inside diameter of your tubing- this measurement will determine the corresponding expanding stem diameter needed. Not sure how to measure or don't see the size you need? Call us or send us a message. • Brake options include a top lock brake (TLB) or a total lock brake (TTL). The top lock brake (TLB), which is featured on 3", 3-1/2", 4", and 5" wheel sizes, places a positive locking force against the wheel tread locking the wheel only. The total lock brake (TTL), which is featured on all wheel sizes, 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.
