Description
Rigid Type Heavy Duty 4″ × 2″ Polyurethane (PU) Caster Wheel
Heavy Duty 4 x 2 PU Caster Wheel is a wide fixed-direction industrial caster designed for platform trolleys, warehouse carts, fabricated equipment, machinery stands and compatible material-handling applications requiring stable straight-line movement.
Its 4-inch diameter and 2-inch wide polyurethane wheel provides a broad floor-contact area together with firm and durable rolling performance for clean and reasonably smooth warehouse, workshop and industrial floors.
➡️ Stable Straight-Line Movement
The rigid heavy-duty bracket keeps the wheel facing in one fixed direction. It supports predictable forward-and-backward movement without sideways swivelling, helping compatible trolleys and equipment maintain directional stability.
⚙️ Durable Polyurethane Wheel
Polyurethane provides a firm and durable rolling surface suitable for demanding material-handling applications. It offers a practical balance between wear resistance, controlled rolling and protection for suitable industrial floors.

🧭 Predictable Directional Control
The rigid caster configuration helps trolleys and mobile equipment travel in a controlled straight line. This is useful where directional stability is more important than tight turning or multidirectional manoeuvring.
🛡️ Suitable for Finished Industrial Floors
The polyurethane rolling surface is suitable for clean and reasonably smooth floors where durability, controlled movement and reduced harsh contact are important. Confirm suitability before using the wheel on delicate or specialised floor finishes.
📏 Wide 2-Inch Wheel Profile
The approximately 2-inch-wide wheel provides a broader floor-contact area than narrow general-purpose caster wheels. This supports improved stability and more even floor contact during normal material-handling use.
📦 Common Uses
Suitable for platform trolleys, warehouse carts, industrial utility carts, fabricated equipment, machinery stands, movable workstations, workshop equipment and compatible material-handling applications requiring stable straight-line movement.
🏭 Recommended Operating Surfaces
Polyurethane caster wheels are generally suited to clean and reasonably smooth warehouse, workshop and industrial floors such as epoxy-coated floors, finished concrete and smooth cement.
Continuous use on broken concrete, sharp metal debris, deep floor joints, rough outdoor ground or highly uneven surfaces may increase rolling resistance and wheel wear. A Jeep-cut rubber or pneumatic wheel may be more appropriate for rougher conditions.
🛞 Choosing the Correct Caster Type
Choose this rigid heavy-duty PU version when the trolley or equipment requires stable and predictable forward-and-backward movement.
Choose the matching swivel heavy-duty PU version when easy turning and multidirectional movement are required.
For additional ground clearance, consider a larger 5″ × 2″ heavy-duty PU caster after confirming the mounting dimensions and required working-load capacity.
📐 Check Compatibility Before Ordering
Before ordering, confirm the 4-inch wheel diameter, 2-inch wheel width, overall caster height, mounting-plate dimensions, bolt-hole spacing and available clearance on your trolley or equipment.
The product page does not currently publish a verified working-load capacity or complete mounting measurements. Confirm the required load, number of casters, equipment design and operating conditions with JTC before installation.

❓ Frequently Asked Questions
What does PU mean?
PU means Polyurethane. It is a durable wheel material commonly used for industrial caster wheels where wear resistance and firm rolling performance are important.
Can this caster turn sideways?
No. This is a rigid fixed caster designed for stable forward-and-backward movement without sideways swivelling.
Does this caster have a brake?
No. This is the rigid non-locking version. Choose a swivel or swivel-and-lockable caster when turning or parking control is required.
What does 4″ × 2″ mean?
The wheel has an approximately 4-inch diameter and an approximately 2-inch tread width.
Is polyurethane the same as rubber?
No. Polyurethane is generally firmer than ordinary soft rubber and is selected where durability, controlled rolling and wear resistance are priorities.
Is polyurethane the same as nylon?
No. Polyurethane generally provides more cushioning than hard nylon, while nylon normally provides a harder rolling surface on smooth floors.
What is the working-load capacity?
The current product page does not publish a verified working-load capacity. Confirm the required application, number of casters and total load with JTC before ordering.
Where does this wheel perform best?
It performs best on clean and reasonably smooth warehouse, workshop, epoxy-coated and finished concrete floors.
Can rigid and swivel casters be used together?
Yes. A common trolley configuration 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.
