Description

This industrial caster wheel is a 3″ x 1 1/4″ High Capacity Rubber Wheel that is non-marking in nature and is bonded to a plastic center. This institutional caster wheel was designed to use a ⅜” axle and the tread width of the tire is 1-¼”.  The durometer of this soft gray rubber caster wheel is 65A, 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. 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. Size shown in photo is 5″ x 1 1/4″.

The RH High Capacity Soft Gray Rubber Wheel is a non-marking industrial wheel for heavy duty casters, with a gray, injection-molded thermoplastic rubber tire mechanically bonded to a polyolefin (industrial plastic) center, providing a softer, quiet ride than polyurethane and resisting many chemicals and solvents, making it popular in pharmaceutical laboratories, hospitals, food service, and institutional applications on dry factory floors. This high capacity soft gray rubber caster wheel, featuring annular ball bearings to maximize its rated capacity (up to 700 lbs for the 8”x2”), absorbs shock, rolls over small objects, protects costly floor surfaces, and minimizes vibration, prolonging equipment life and protecting cargo, but it’s not suited for shock, overloading, abuse, obstructions, poor floors, or prolonged standing loads, as the tire may take a permanent set or develop flat spots.

The RH High Capacity Soft Gray Rubber Wheel has higher rolling resistance, so it does not roll easily under load—reduce capacity ratings by 50% and select the largest practical wheel diameter (1.25” wide in 3”, 3.5”, 4”, and 5” diameters, and 2” wide in 4”, 5”, 6”, and 8” diameters) for manual movement, as load capacity ratings do not account for the effort required to manually move a load (drawbar pull measured in pounds). The bonding agent holding the rubber tire to its polyolefin center can be affected by exposure to some chemicals, impact, overloading, and the buildup of heat, so this heavy duty wheel works best in dry factory floors for industrial applications, offering a quiet, shock-absorbing ride while protecting floors and equipment in sensitive settings.  Contact Caster City if you have any questions about how to use thermoplastic rubber wheels.

FAQ

What is the RH High Capacity Soft Gray Rubber Wheel?

The RH High Capacity Soft Gray Rubber Wheel is a non-marking, injection-molded thermoplastic rubber tire with a 65A soft durometer, mechanically bonded to a polyolefin (industrial plastic) center. It features a 304 stainless steel annular ball bearing for superior corrosion resistance, making it a high-performance choice for stainless steel casters in wet or corrosive environments like food processing, pharmaceuticals, hospitals, and labs. Available in 3”, 4”, and 5” diameters with a 1-1/4″ tread width, 1-5/8″ hub length, and 3/8″ axle diameter.

What environments and applications work best for the RH High Capacity Soft Gray Rubber Wheel?

The RH wheel is ideal for wet and corrosive environments, such as food processing plants, pharmaceutical labs, hospitals, and cleanrooms, where stainless steel casters are used. It’s perfect for carts carrying sensitive equipment like medical devices, lab instruments, or food service items, providing floor protection and vibration reduction in hygienic settings.

What are the main benefits of the RH High Capacity Soft Gray Rubber Wheel?

The RH wheel delivers a quiet, shock-absorbing ride with its 65A soft durometer, protects floors and equipment, resists water and mild chemicals, and minimizes vibration. Its 304 stainless steel bearing enhances corrosion resistance and durability, outperforming standard-duty gray rubber wheels for stainless steel caster applications in demanding environments.

How does the RH High Capacity Soft Gray Rubber Wheel perform in terms of rolling resistance?

The RH wheel’s 65A soft durometer results in higher rolling resistance, requiring more effort to move under load. Reduce capacity by 50% for manual movement and choose the largest practical diameter for easier rolling on smooth or wet floors with stainless steel casters.

What are the limitations of the RH High Capacity Soft Gray Rubber Wheel?

It’s not suited for shock, overloading, abuse, obstructions, poor floors, or prolonged standing loads, as it may develop flat spots. Avoid extreme heat or certain harsh chemicals, even with its corrosion-resistant 304 stainless steel bearing.

Can the RH High Capacity Soft Gray Rubber Wheel be used in wet or corrosive environments?

Yes, the RH wheel withstands water and mild chemicals, and its 304 stainless steel bearing ensures corrosion resistance. Pair it with a stainless steel caster frame for optimal performance in wet or corrosive settings like food processing or hospital environments.

What industries commonly use the RH High Capacity Soft Gray Rubber Wheel?

The RH wheel is popular in pharmaceuticals, hospitals, food service, cleanrooms, and labs, where its non-marking, high-capacity build, corrosion-resistant stainless steel bearing, and quiet operation make it ideal for stainless steel casters in hygienic, wet environments.

How does the RH High Capacity Soft Gray Rubber Wheel compare to polyurethane wheels?

The RH wheel, with its 65A soft durometer, offers a softer, more shock-absorbing ride than polyurethane, protecting equipment and floors while reducing vibration. Its 304 stainless steel bearing adds corrosion resistance for stainless steel casters, though it has higher rolling resistance, making it perfect for sensitive, wet settings.

What maintenance does the RH High Capacity Soft Gray Rubber Wheel require?

The RH wheel’s 304 stainless steel annular ball bearing requires no maintenance, ensuring long-term, smooth performance in wet or corrosive stainless steel caster applications with minimal upkeep.

Why is the RH High Capacity Soft Gray Rubber Wheel ideal for stainless steel casters in hospitals?

The RH wheel excels with stainless steel casters in hospitals, offering a stronger, higher-quality build than standard-duty gray rubber wheels. Its 65A soft durometer provides a quiet, shock-absorbing ride that protects floors and equipment, while the 304 stainless steel bearing ensures corrosion resistance in wet, hygienic settings, lasting over 20 years in dry conditions.

How does the RH High Capacity Soft Gray Rubber Wheel compare to standard-duty gray rubber wheels?

The RH wheel greatly exceeds standard-duty gray rubber wheels with its 65A soft durometer, offering superior strength, shock absorption, and floor protection. Its 304 stainless steel bearing enhances corrosion resistance, making it a premium choice for stainless steel casters in demanding institutional and industrial applications.
