Description
Rigid Type 4″ TPR (Thermoplastic Rubber) Caster Wheel
Rigid Type 4″ TPR (Thermoplastic Rubber) Caster Wheel is a fixed-direction wheel designed for utility trolleys, display racks, office carts, service equipment and compatible indoor applications requiring stable straight-line movement.
Its 4-inch thermoplastic rubber wheel provides a softer rolling surface than hard nylon or hard-plastic wheels, helping reduce trolley noise, absorb minor vibration and provide better protection for finished indoor floors.
➡️ Stable Straight-Line Movement
The rigid bracket keeps the wheel facing in one fixed direction. It moves forward and backward without swivelling sideways, providing predictable tracking for compatible carts and equipment.
🔇 Quieter Indoor Rolling
The softer TPR tread helps reduce rolling noise and vibration compared with harder wheel materials, making it suitable for offices, shops, showrooms and other indoor areas where quieter movement matters.

🛡️ Better Protection for Finished Floors
The softer thermoplastic rubber tread provides more cushioning than hard nylon and hard-plastic wheels. This helps reduce harsh contact with suitable finished floors during normal indoor use.
〰️ Reduced Vibration
The rubber-like TPR tread absorbs minor vibration from floor joints and small surface imperfections, supporting smoother trolley movement and helping reduce vibration transferred to the trolley frame.
📦 Common Uses
Suitable for utility carts, office trolleys, display racks, movable shelving, shop equipment, service carts, storage units and compatible indoor fixtures requiring stable straight-line movement.
🏢 Recommended for Indoor Floors
TPR wheels are best suited to clean and reasonably smooth indoor surfaces such as tile, epoxy-coated floors and finished concrete.
Continuous use on broken concrete, sharp debris, rough outdoor ground or highly uneven surfaces may increase rolling resistance and tread wear. A heavy-duty rubber, Jeep-cut or pneumatic wheel may be more suitable for rougher conditions.
🛞 Choosing the Correct Caster Type
Choose this rigid version when the trolley or equipment requires stable and predictable forward-and-backward movement.
Choose the matching swivel version when easy turning and multidirectional movement are required.
Choose the matching swivel-and-lockable version when easy turning and parking control are both required.
📐 Check Compatibility Before Ordering
Before ordering, confirm the wheel diameter, overall caster height, mounting-plate dimensions, bolt-hole spacing and available clearance on your trolley or equipment.

❓ Frequently Asked Questions
What does TPR mean?
TPR means Thermoplastic Rubber. It provides a softer, more cushioned rolling surface than hard nylon or hard-plastic caster wheels.
Can this caster turn sideways?
No. This is a rigid fixed caster designed for forward-and-backward movement.
Is this a rubber wheel?
It is a thermoplastic rubber wheel. TPR provides rubber-like cushioning and grip while being manufactured as a thermoplastic material.
Is it suitable for quiet indoor use?
Yes. TPR wheels are commonly selected where quieter rolling, floor protection and smoother trolley movement are important.
What is the working-load capacity?
The current product page does not publish a verified load capacity. Confirm the required application and load with JTC before ordering.
Where does this wheel perform best?
It performs best on clean and reasonably smooth indoor tile, epoxy and finished concrete floors.
Can rigid and swivel casters be used together?
Yes. A common trolley arrangement uses two rigid casters for directional stability and two swivel casters for easier steering.
Is mounting hardware included?
Mounting bolts and installation hardware are not included unless separately specified.
