Description
4″ Gray High Capacity Rubber Wheel. Ball Bearings in the Wheel.
Shown here at Caster City with 5″ high capacity TPR soft gray rubber wheel.
The RH High Capacity Soft Gray Rubber Wheel in the Zinc-Plated Total Locking Caster Model 3A is a great pick for light industrial casters. It features soft non-marking TPR rubber—gray injection molded thermoplastic rubber tires—mechanically bonded to a polyolefin center. The wheel is made for 3”, 4”, and 5” diameters (1.25” wide) and supports up to 350 lbs per wheel at room temperature on smooth floors in hospitals, pharmaceutical labs, food service, and institutional applications. The soft gray rubber caster wheel has a maintenance-free annular sealed ball bearing. It provides a softer ride than polyurethane, withstands exposure to many chemicals and solvents, absorbs shock, rolls over small objects, protects costly floor surfaces, and minimizes vibration. The metal caster yoke assembly, constructed from stamped steel and zinc-plated to resist corrosion, includes a ⅜” diameter axle bolt and a ½” diameter steel rivet holding the swivel raceways together, with two rows of ball bearings for smoother swiveling. A total lock brake locks both the wheel and the swivel on a swivel caster at the same time. This makes it ideal for a total locking industrial caster needing a quiet, high-capacity wheel and a secure metal fork assembly for sensitive settings.
The RH High Capacity Soft Gray Rubber Wheel works best on dry factory floors. It excels with its cost-effective design, keeping smooth rolling and floor protection in hospital or lab setups, with soft non-marking TPR rubber offering better operating traits than any other wheel material. The metal caster assembly enhances durability with a dust cover shielding the swivel bearings from dirt, giving reliable performance. The total lock brake feature ensures safety by immobilizing both the wheel and swivel action when the metal pedal brake is engaged—reduce capacity ratings by 50% and pick the largest practical diameter for manual movement to lessen effort. The bonding agent holding the rubber tire to its polyolefin center can be affected by some chemicals, impact, overloading, or heat buildup, but this wheel and metal fork assembly shine in clean, dry environments, making these zinc-plated casters a smart choice for institutional applications needing a gentle, protective wheel.
