Description
3″ Gray Soft Rubber Wheel. Brake Locks both the Swivel and Wheel Shown in photo with 5″ wheels. This 3A stem caster is our stainless steel total locking institutional caster which uses the same Model 3 1-¼” wide wheels. A total lock brake locks the swivel and the wheel. It latches them simultaneously by one foot on the brake pedal. The plate caster swivel model 3A has a metal total lock pedal. It is simple to turn on but not as simple to let go as the nylon brake pedal featured on K3. The metal lock can only be reached if the release deise with the type of your shoe which may not allow enough burden to be utilized to unlock the brake. This is not an issue with the nylon brake pedal on model k3. The metal total lock brake pedal is an alternative on 3a swivels. The metal pedal is shown slightly under the mounting plate of the swivel caster and slightly over the wheel. The metal pedal extends behind the wheel so the toe of your foot can simply reach the activation pedal. The metal pedal digs into polyurethane and rubber tires more than the nylon pedal. The amount of the metal pedal total lock brake is more than the cost of a total lock brake with a nylon pedal. Neither type of total lock brake are possible on a caster rigid.
This gray rubber caster wheel is made from injection-molded soft gray rubber, making it a non-marking wheel. 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 90-95A, making it ideal for vibration and noise reduction. The sealed ball bearing in this gray soft rubber caster wheel is bushed down to ⅜” with two plastic spanner bushings that also act as thread guards, guarding the bearing from direct and indirect moisture contact. 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.

Are the stainless steel casters with RF Soft Gray Rubber Wheels good for standing loads?
Nope, the stainless steel casters with RF Soft Gray Rubber Wheels don’t work for standing loads—don’t exceed 50% of the rated capacity for applications parked for long periods, as the tires may take a permanent set or develop flat spots.
How do I protect the RF Soft Gray Rubber Wheel in the Stainless Steel Total Locking Stem Caster Model 3A from damage?
Keep the RF Soft Gray Rubber Wheel in the Model 3A total lock caster free from shock, overloading, abuse, obstructions, poor floors, rack washers, and exposure to some chemicals, impact, or heat buildup, which can affect the bonding agent holding the tire to its center and the stainless steel construction’s performance.

The total locking casters with RF Soft Gray Rubber Wheels provide a softer ride than polyurethane, absorb shock, minimize vibration, and roll over small objects quietly, with the stainless steel assembly ensuring corrosion resistance and stability, making them a smart choice for institutional washdown applications without a big price tag.
What’s the load capacity for the RF Soft Gray Rubber Wheel in the stem mount caster, and how do I adjust for manual movement?
The RF Soft Gray Rubber Wheel in the stem mount caster holds up to 300 lbs per wheel and per caster at room temperature, but reduce capacity ratings by 50% and pick the largest practical diameter for manual movement to lessen the effort required.
How does the metal pedal brake work on the Total Locking Caster Model 3A with the RF Soft Gray Rubber Wheel and stainless steel assembly?
The metal pedal brake on the Total Locking Caster Model 3A locks both the wheel and the swivel bearing at the same time, completely immobilizing the stainless steel assembly and turning it into an extension of the leg, keeping the caster secure for safety in stationary applications like carts or tables.
Why is the total lock brake on the Model 3A stem mount caster with RF Soft Gray Rubber Wheels important for safety in hospital or lab settings?
The total lock brake on the Model 3A stem mount caster with RF Soft Gray Rubber Wheels locks the swivel and the wheel, completely immobilizing the stainless steel assembly to prevent the object—like a cart, table, or lab equipment—from moving when someone leans against it while working, cleaning, or setting up, ensuring safety during such tasks. Total locking casters are important because in cutting, welding, sawing, or similar tasks, people will lean against the worktable while doing their dangerous cut, and the total lock caster prevents anything in the caster from moving, totally immobilizing wheel and swivel rotation of the caster.
What makes the total lock brake on the Model 3A total locking caster a trusted safety feature for institutional washdown applications?
The total lock brake on the Model 3A total locking caster ensures complete immobilization by locking both the wheel and the swivel bearing simultaneously, transforming the caster into a rigid extension of the equipment leg, preventing any movement during critical tasks like cleaning, maintenance, or setup in institutional washdown settings, making it a trusted choice for safety-focused environments.
How does the total lock brake on the Model 3A total locking industrial caster enhance stability for hospital or lab equipment in washdown environments?
The total lock brake on the Model 3A total locking industrial caster locks the wheel and swivel bearing at the same time, fully immobilizing the stainless steel assembly to eliminate any risk of movement, ensuring hospital or lab equipment—like carts, tables, or workstations—stays firmly in place during cleaning, sterilization, or setup in washdown environments, providing unmatched stability and safety in high-precision settings. Total locking casters are important because in cutting, welding, sawing, or similar tasks, people will lean against the worktable while doing their dangerous cut, and the total lock caster prevents anything in the caster from moving, totally immobilizing wheel and swivel rotation of the caster.
