6 Inch Swivel Directional Lock Caster Iron Core PU Wheel 350kg Heavy Duty Caster

The smart-control heavy duty caster for large appliances and commercial laundry. This 6-inch swivel caster features a side-mounted directional lock lever—flip it to convert from free 360° swivel to straight-line rigid tracking in one motion. Combined with dual-spring shock absorption, PU-on-iron-core wheel, and 6203 precision bearings, it delivers 350 kg of controlled, stable mobility. Fully customizable.

Two Modes. One Caster. Total Control.

Our 6-inch Swivel + Directional Lock Caster solves the #1 complaint about swivel casters: they drift sideways when you don't want them to. The side-mounted directional lock lever lets you instantly switch between:

1. Free Swivel Mode – Full 360° rotation for tight-space maneuverability. Navigate crowded laundry rooms, appliance showrooms, and narrow warehouse aisles with ease.
2. Straight-Line Mode – Flip the directional lock lever and the swivel head locks at 0°. The caster now tracks perfectly straight—just like a rigid caster. Ideal for towing heavy appliances down long corridors or feeding carts along conveyor lines. Flip it back and you're swiveling again.

No foot brake, no wheel lock—just pure directional control. This is the preferred choice for operations that need both maximum maneuverability AND straight-line stability, without the complexity of a dual-brake system.

The polyurethane tread on a solid iron core delivers a non-marking, wear-resistant rolling surface with the structural strength to handle 350 kg per caster. The dual-spring steel suspension plate absorbs vibration from uneven floors—critical for commercial washing machines during spin cycles. A dust-protective lid keeps lint and debris out of the spring mechanism.

As a factory-direct manufacturer, we offer full customization in wheel material, temperature range, and load capacity.

💡 Real-World Example: A commercial laundry cart needs to navigate a tight washroom (free swivel), then travel 30 meters down a straight corridor to the folding station (directional lock engaged). One caster, two modes, zero compromise.

• Laundry carts & trolleys – swivel through narrow washroom doors, lock for straight runs down corridors
• Linen collection bins – maneuver in tight spaces, then lock for stable transport
• Ironing & pressing stations – directional lock prevents cart drift during operation

• Washing machine assembly lines – free swivel for positioning at each station, lock for conveyor transfer
• Refrigerator & freezer transport – navigate tight delivery hallways, then lock for straight ramp loading
• Appliance showroom displays – easy to rearrange, locks in place for customer viewing

• Production line dollies – switch between free movement and locked straight-line feeding
• Generator & compressor housings – directional lock prevents unwanted drift during placement
• Medical imaging equipment – precise straight-line positioning

• Hotel housekeeping carts – navigate guest room corridors with control
• Hospital linen services – hygienic, directional stability in busy hallways
• School maintenance carts – versatile for both classroom access and hallway transport

• High-temperature above +120 °C continuous – choose phenolic or steel wheels
• Outdoor rough terrain / gravel – pneumatic tires recommended
• Prolonged direct sunlight / UV – unless UV-stabilized PU specified
• Speeds exceeding 4–6 km/h – designed for controlled manual movement
• Applications requiring wheel lock – choose our Single Brake or Dual Brake models instead

Q: Does the directional lock stop the wheel from rolling?

A: No. It only locks the swivel head so the wheel can only roll forward/backward in a straight line. The wheel itself continues to rotate freely. If you need to stop wheel rotation, see our Brake models.

Q: Can I engage the directional lock while the cart is moving?

A: We recommend stopping the cart before engaging the lock lever to avoid sudden resistance. Once engaged, the caster will track straight.

Q: Is the directional lock lever reversible (left/right)?

A: Standard is right-side mount. Left-side configuration is available as a custom option—specify when ordering.

Q: Can I get this with a wheel brake too?

A: Yes! That's our Dual Brake model (wheel brake + directional lock). Contact us for details.

Q: What is the MOQ?

A: Standard MOQ applies. Contact us for exact numbers based on your region and configuration mix.
