Description

4″ Gray Soft Rubber. Shown in photo with 5″ wheels. This Stainless Steel Rigid Caster Model 3 is formed from stamped 304 stainless steel legs that are joined horizontally to the mounting plate. This rigid stem caster is capable of up to 300 lbs with the proper wheel chosen. The diameter axle is ⅜” and has a bolt with lock nut. Other lube axle bolt is available with a lubed fitting in the bolt head for greasing the wheel. This stem caster is purchased when direct line travel is important over elongated distances. When moving huge cargo or extreme weighted loads, choose the biggest practical wheel diameter. High polish (mirror) finish is available upon request. This rigid caster is NSF and ROHS compliant. The mounting plate for the Stainless Steel Caster Model 3 is 2 3/8” x 3 5/8” and the hole pattern is slotted to: 1 3/4” x 2 7/8” – 3” and is built to use a mounting bolt size of 5/16”.

This injection molded soft gray rubber tire has had the carbon black removed from the rubber which makes it a non-marking caster wheel, suitable for applications such as a hospital. This institutional caster wheel was designed to use a ⅜” axel and the tread width of the tire is 1-¼”.The durometer of this soft gray rubber caster wheel is 90-95A, making it ideal for vibration and noise reduction. This caster wheel has a sealed precision ball bearing protected with plastic spanner bushings that reduce the inner diameter of the axle, act as thread guards, and guard the bearing from indirect and direct moisture exposure. These caster wheels should not be left standing under load for extended periods as the tires may take a permanent “set” or develop flat spots.

In food service areas, hospitals, and science research labs where stainless steel casters on carts need to roll silently without leaving marks on the floors, Caster City’s RF Soft Gray Rubber Caster Wheel handles the task with no trouble. Its gray non-marking thermoplastic rubber tire, securely bonded to a polyolefin center, takes in shocks to safeguard the cart and delicate items like lab samples, easily managing small debris. This wheel keeps noise and vibration low, making it a perfect fit for hospitals, pharmaceutical labs, and food service settings where clean, quiet operation is essential.

The soft gray rubber RF wheel in a stainless steel caster stands up to chemicals and solvents without a problem, but it’s not built for harsh treatment—steer clear of overloading, rough surfaces, or leaving it under a load for extended periods, as that can lead to flat spots. When pushing the cart by hand, reduce the load capacity by 50% for easier movement, and opt for the largest diameter possible for a steadier roll. Made for dry factory floors, the RF Soft Gray Rubber Caster Wheel in a stainless steel caster shields costly surfaces and extends equipment life, though you’ll want to watch out for harsh impacts or specific chemicals that could impact the bonding over time.
