Description

Swivel Radius for 3 inch PTB brake = 4-3/8″ ยฑ 1/8″

Plate Caster Model 3 is made using a stamped steel construction and is bright zinc plated for corrosion resistance.ย  The mounting plate is 2 3/8โ€ x 3 5/8โ€ and the hole pattern is slotted to: 1 3/4โ€ x 2 7/8โ€ โ€“ 3โ€ and is designed to use a mounting bolt size of 5/16โ€.ย  This plate caster uses a โ…œโ€ diameter axle and the swivel caster is held together by a 1โ„2” diameter rivet.ย  This institutional plate caster is constructed with two ball bearings on hardened raceways to ensure life of the caster.ย  There is a metal dust cap protecting the swivel raceways to shield them from dirt and dust.ย  Features wheels with 1-ยผโ€ and 1-1โ„2” tread widths.ย  This Zinc Plated caster is NSF listed.

Caster City manufactures this plate caster in Stainless Steel Caster Model 3.ย  This caster comes standard with two high temperature white seals in the swivel bearing that has a temperature range of -20F to 450F.ย  Also come with a grease fitting on the dust cover and axle, and buffed to a smooth reflective surface.

Caster City also manufactures this plate caster in Economy Stainless Steel Plate Caster Model K3.ย  Constructed with S304 stainless steel and comes with no dust cap or grease fitting on the swivel making it economically efficient for most applications.

These caster wheels have blue, non-marking injection molded thermoplastic rubber tires mechanically and chemically bonded to a polyolefin ( industrial plastic ) center. They are popular on equipment in Pharmaceutical Laboratories, Hospitals, Food Service and other Institutional applications. These caster wheels provide a softer ride than polyurethane and yet withstand exposure to many chemicals and solvents. They can be used in industrial applications which do not involve shock, overloading, abuse, obstructions, poor floors or storage (standing) loads. The High Capacity Soft Gray Rubber Caster Wheel has annular ball bearings to maximize its rated capacity.

Soft rubber provides more desirable operating characteristics than any other wheel material. These gray soft rubber wheels are non-marking, quiet, absorb shock (prolonging equipment life and protecting cargo), can roll over small objects, protects costly floor surfaces, and minimizes vibration. They fall short of perfection in their limitation under load โ€“ they do not roll easily. Load capacity ratings do not take into account the effort required to manually move a load (drawbar pull measured in pounds). If cargo is to be moved manually on these gray soft rubber caster wheels, reduce capacity ratings by 50% and select the largest practical wheel diameter. These caster wheels should not be left standing under load for extended periods as the tires may take a permanent โ€œsetโ€ or develop flat spots. They can be used on almost any dry factory floor. The bonding agent which holds the rubber tire to its polyolefin center can be affected by exposure to some chemicals, impact, overloading, and the buildup of heat.

 

FAQ

Plate Caster Model 3 with RHB High Capacity Soft Blue Rubber (TPR) Wheels

What is TPR in the Plate Caster Model 3โ€™s RHB High Capacity Soft Blue Rubber wheels?

TPR (Thermoplastic Rubber) is a non-marking, injection-molded blue rubber mechanically bonded to a polyolefin core in the RHB High Capacity Soft Blue Rubber wheels. Itโ€™s elastic, tear-resistant, and quieter than polyurethane, providing shock absorption and floor protection for hospitals, labs, and food service. It resists light chemicals but may develop flat spots under prolonged loads.

Why choose RHB High Capacity Soft Blue Rubber wheels for hospital equipment?

The non-marking blue TPR wheels on the Plate Caster Model 3 roll quietly, absorb shock, and protect floors like tile or linoleum, making them perfect for hospital carts or beds. Theyโ€™re NSF-listed and ideal for dry institutional settings, preserving equipment and floors.

Can RHB High Capacity Soft Blue Rubber wheels handle chemicals in pharmaceutical labs?

Yes, the blue TPR tires resist many chemicals and solvents, suitable for dry lab environments. Harsh chemicals or heat buildup may weaken the tireโ€™s bond to the polyolefin core, so avoid heavy exposure.

How hard is it to push the Plate Caster Model 3 with RHB High Capacity Soft Blue Rubber wheels?

TPR wheels need more effort under load. For manual pushing, reduce the 350 lbs per wheel capacity by 50% (to 175 lbs) and select the 5โ€ diameter for easier movement on smooth, dry factory floors.

Can I leave the Plate Caster Model 3 with RHB High Capacity Soft Blue Rubber wheels under load?

No, avoid prolonged standing loads. The blue TPR tires can develop flat spots or a permanent โ€œset,โ€ reducing performance in institutional settings like schools or food service.

Are RHB High Capacity Soft Blue Rubber wheels suitable for rough industrial floors?

No, these TPR wheels are designed for smooth, dry factory floors without obstructions. Theyโ€™re best for institutional applications like hospitals or labs, not abusive industrial environments.

Do RHB High Capacity Soft Blue Rubber wheels on the Plate Caster Model 3 require maintenance?

No, the sealed annular ball bearings are maintenance-free, keeping out dust for smooth, lasting performance on dry floors in pharmaceutical labs, hospitals-github.com, or food service settings.

What are the mounting specifications for the Plate Caster Model 3 with TPR wheels?

The Plate Caster Model 3 has a 2 3/8โ€ x 3 5/8โ€ top plate with a slotted bolt hole pattern of 1 3/4โ€ x 2 7/8โ€ to 3โ€, using 5/16โ€ bolts, fitting standard institutional carts or shelving.

Can the Plate Caster Model 3 with RHB High Capacity Soft Blue Rubber wheels be used in wet environments?

The zinc-plated steel frame isnโ€™t suited for wet, washdown, or corrosive conditions. Use these blue TPR wheels in dry settings like labs or hospitals to prevent rust and ensure durability.

Is the Plate Caster Model 3 with RHB High Capacity Soft Blue Rubber wheels NSF-listed for food service?

Yes, the Plate Caster Model 3 is NSF-listed, ideal for food service or medical settings in dry environments. Verify with the supplier that the blue TPR wheels meet NSF standards for your use.

How do I replace the RHB High Capacity Soft Blue Rubber wheel on the Plate Caster Model 3?

Match the wheelโ€™s diameter (3โ€, 4โ€, or 5โ€), tread width (1-1/4โ€ or 1-1/2โ€), and 3/8โ€ axle. Choose a non-marking blue TPR wheel with sealed annular ball bearings to maintain the quiet, smooth roll.

How do RHB High Capacity Soft Blue Rubber wheels compare to polyurethane for institutional casters?

The blue TPR wheels are softer, quieter, and better at shock absorption than polyurethane, protecting floors and cargo in hospitals or labs. They roll less easily under load and arenโ€™t suited for rough floors.
