Description

3″ Black/Gray Polyurethane 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 Model. 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 burrows 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.

What material is the Polyurethane on Polyolefin Caster Wheel made from in the Stainless Steel Total Locking Stem Caster Model 3A?

The Polyurethane on Polyolefin Caster Wheel in the Model 3A total locking caster has non-marking injection molded polyurethane tires mechanically bonded to a polyolefin center, available in red, gray, black, or blue colors, with a Shore 60D durometer for smooth rolling in sensitive settings.

What applications are best for the total locking caster with Polyurethane on Polyolefin Caster Wheels in labs and hospitals?

The total locking caster with Polyurethane on Polyolefin Caster Wheels is perfect for labs, hospitals, and food processing plants in institutional settings, where a stem mount caster moves equipment like carts and tables on smooth floors in dry or wet washdown environments, keeping equipment secure with its total lock brake.

What bearing type comes with the Polyurethane on Polyolefin Caster Wheel in the total lock caster?

The Polyurethane on Polyolefin Caster Wheel in the total lock caster comes standard with precision sealed ball bearings, keeping smooth rolling in institutional applications on smooth floors.

What stem types are available for the Stainless Steel Total Locking Stem Caster Model 3A with Polyurethane on Polyolefin Caster Wheels?

The Stainless Steel Total Locking Stem Caster Model 3A with Polyurethane on Polyolefin Caster Wheels is compatible with grip ring stems, threaded stems, round stems, square stems, stems with cross holes (both round and square), and expanding rubber stems, providing versatile mounting options for institutional equipment like carts and tables in labs or hospitals.

Can the Polyurethane on Polyolefin Caster Wheel in the total locking caster roll on rough floors?

No, the Polyurethane on Polyolefin Caster Wheel in the total locking caster is built for smooth floor surfaces only—rough floors or obstructions will damage these stainless steel casters and shorten their life.

Are the stainless steel casters with Polyurethane on Polyolefin Caster Wheels good for standing loads?

Nope, the stainless steel casters with Polyurethane on Polyolefin Caster Wheels don’t work for standing loads—don’t exceed 70% of the rated capacity for applications parked for prolonged periods, as the tires may take a permanent set.

How do I protect the Polyurethane on Polyolefin Caster Wheel in the Stainless Steel Total Locking Stem Caster Model 3A from damage?

Keep the Polyurethane on Polyolefin Caster 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.

Do the Polyurethane on Polyolefin Caster Wheels in the total lock caster leave marks on floors in institutional settings?

No, the non-marking injection molded polyurethane tire build of the Polyurethane on Polyolefin Caster Wheels in the total lock caster is ideal for protecting floor surfaces in labs or hospital washdown areas.

Why are the total locking casters with Polyurethane on Polyolefin Caster Wheels good for institutional washdown applications?

The total locking casters with Polyurethane on Polyolefin Caster Wheels roll easier than gray rubber on smooth floors, withstand exposure to many chemicals, and provide smooth rolling 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 and temperature range for the Polyurethane on Polyolefin Caster Wheel in the stem mount caster, and how do I adjust for prolonged parking?

The Polyurethane on Polyolefin Caster Wheel in the stem mount caster holds a max capacity of 300 lbs per wheel and per caster at room temperature and works from 32°F to 180°F, but don’t exceed 70% of the rated capacity for applications parked for prolonged periods to avoid flat-spotting.

How does the metal pedal brake work on the Total Locking Caster Model 3A with the Polyurethane on Polyolefin Caster 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 Polyurethane on Polyolefin Caster Wheels important for safety in hospital or lab settings?

The total lock brake on the Model 3A stem mount caster with Polyurethane on Polyolefin Caster 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.
