3″ Gray Soft Rubber Wheel – Stainless Steel 3

Description

3″ Gray Soft Rubber. Shown in photo with 5″ wheels. Plate Caster Stainless Steel Rigid Model 3 is formed from stamped 304 stainless steel legs that are welded 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 necessary over elongated distances.  When moving huge cargo or heavy 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”.

The “RF” soft gray rubber caster wheel is a non-marking soft rubber tire locked to an industrial plastic center. This caster wheel is 1-¼” wide and is designed to use a ⅜” axle.This soft gray rubber caster wheel comes with a durometer of 90-95A, making it excellent for indoor usage on smooth surfaces to reduice noise and vibration. 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. Injection molded caster wheels are not designed to carry large amounts of weight in static load applications, please consult with us for a better choice.

In a food service industry, hospitals, science and research labs, where stainless steel casters on carts need to roll quietly without marking the floors, Caster City’s RF Soft Gray Rubber Caster Wheel gets the job done without a hitch. Its gray non-marking thermoplastic rubber tire, mechanically bonded to a polyolefin center, absorbs shocks to protect the cart and fragile food trays, handling small debris with ease. This wheel reduces noise and vibration, making it ideal for hospitals, pharmaceutical labs, and food service environments where clean, quiet performance is a priority.

The soft gray rubber RF wheel in a stainless steel caster can handle exposure to chemicals and solvents without breaking a sweat, but it’s not designed for rough abuse—avoid overloading, uneven floors, or letting it sit under a load for too long, as that can cause flat spots. If you’re moving the cart by hand, drop the load capacity by 50% to make pushing easier, and choose the largest diameter you can for a smoother roll. Designed for dry factory floors, the RF Soft Gray Rubber Caster Wheel in a stainless steel caster protects expensive surfaces and prolongs equipment life, but be mindful of harsh impacts or certain chemicals that might affect the bonding over time.
