Swivel Type Lockable Heavy Duty 4″ x 2″ Polyurethane (PU) Caster Wheel

Swivel Type Lockable Heavy Duty 4″ × 2″ Polyurethane (PU) Caster Wheel

Heavy Duty 4 x 2 Lockable PU Caster Wheel is a heavy-duty multidirectional industrial caster designed for platform trolleys, warehouse carts, machinery bases, fabricated equipment and material-handling applications requiring easy steering together with secure parking control.

Its 4-inch diameter and 2-inch wide polyurethane wheel, heavy-duty swivel bracket, top-plate mounting and integrated foot-operated lock provide a practical combination of manoeuvrability, durable rolling performance and controlled stationary positioning.

📋 Technical Specifications

🧭 Easy Steering and Manoeuvring

Unlike a rigid caster, the swivel configuration allows the wheel assembly to change direction as the trolley moves. This supports easier steering through aisles, around corners and within confined warehouse or workshop spaces.

🔒 Parking and Stationary Control

The foot-operated locking mechanism allows the operator to secure the caster when stationary. This is especially useful while loading or unloading a trolley, positioning mobile equipment or keeping a cart from moving unintentionally during normal use.

⚙️ Durable Polyurethane Wheel

Polyurethane provides a firm and durable industrial rolling surface suitable for regular material-handling use. It offers a practical balance between wear resistance, controlled rolling and reduced harsh floor contact compared with extremely hard wheel materials.

🛡️ 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 broad floor-contact area compared with narrow general-purpose casters, supporting better stability and more even contact during normal trolley and industrial equipment use.

🏗️ Heavy-Duty Top-Plate Construction

The heavy-duty metal swivel assembly uses a top-plate mounting configuration for secure attachment to compatible trolley frames, platforms, machinery bases and fabricated equipment.

📦 Common Uses

Suitable for platform trolleys, warehouse carts, industrial utility carts, fabricated equipment, machinery stands, mobile workstations, workshop equipment and material-handling systems requiring both easy steering and parking control.

🏭 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 rubber Jeep-cut or pneumatic wheel may be more appropriate for rougher operating conditions.

🛞 Choosing the Correct Caster Type

Choose this swivel-and-lockable heavy-duty PU version when your trolley or equipment requires easy multidirectional movement together with parking and stationary control.

Choose the standard swivel heavy-duty PU version when easy turning is required but a parking lock is not necessary.

Choose the matching rigid heavy-duty PU version when stable and predictable straight-line movement is required instead of multidirectional steering.

📐 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, swivel radius, brake clearance and available space on your trolley or equipment.

The exact working-load capacity, product weight and complete mounting dimensions should be confirmed before publishing or ordering. Actual suitability also depends on the number of casters, equipment construction, load distribution, floor condition and operating environment.

⚠️ Locking & Safety Guidance

Engage the caster lock only after the trolley or equipment has come to a complete stop. Do not use the parking lock as a dynamic brake while the trolley is moving.

For heavier mobile equipment, use an appropriate number and arrangement of lockable casters and confirm the complete load and operating conditions 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.

What does 4″ × 2″ mean?
The wheel has an approximately 4-inch diameter and an approximately 2-inch tread width.

Can this caster turn through 360 degrees?
Yes. This is a swivel caster designed for multidirectional movement and easier trolley steering.

Does this caster include a lock?
Yes. This model includes an integrated foot-operated locking mechanism for parking and stationary control.

Is this the same as the standard swivel PU caster?
No. The standard swivel version provides multidirectional movement without a parking lock. This version adds an integrated locking mechanism.

Is polyurethane the same as rubber?
No. Polyurethane is generally firmer than ordinary soft rubber and is commonly 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?
A verified working-load capacity for this exact lockable model should be confirmed with JTC before publishing or selecting the wheel for a particular application.

Can rigid, swivel and lockable casters be combined?
Yes. Different caster arrangements may be used depending on the required steering, directional stability and parking control. The correct configuration should be selected according to the trolley design and application.

Can the lock be used to stop a moving trolley?
The lock should be used for parking and stationary positioning after the equipment has stopped. It should not be used as a dynamic braking system.

Is mounting hardware included?
Mounting bolts and installation hardware are not included unless separately specified.
