8 Core Advantages of Plain Bore Red PU Steel Plate Mount Furniture Casters (Type C Lock Brake)
- Smooth Swivel Action: Precision plain bore design ensures smooth, quiet rotation for furniture applications. Easy pushing and repositioning on hard floors.
- Premium PU Wheel — Non-Marking & Quiet: High-quality Polyurethane (PU) tread in Red delivers superior floor protection — completely non-marking with quiet rolling. Ideal for hardwood, tile, and vinyl floors.
- Total Lock Brake (Type C): Simultaneously locks both wheel rotation and swivel movement. Keeps your furniture securely in place. Type C plate brake — easy foot-pedal engagement.
- Steel Bracket — Durable Construction: Durable steel bracket provides excellent structural integrity for daily furniture use. Clean finish suitable for office and home environments.
- Top Plate Bolt-On Mounting: Standard top plate design in rigid (A), swivel (B), and brake (C) configurations. Pre-drilled mounting holes for quick, secure furniture mounting.
- Furniture-Grade Design: Engineered specifically for office and home furniture. Quiet operation and smooth swivel action meet the demands of daily use.
- Consistent Quality: Strict QC processes ensure consistent performance. Each caster load-tested and swivel-tested before shipment.
- Wide Application Temperature Range: Reliable performance from -20°C to +60°C. Consistent rolling quality in varied environments.

FAQ
Q: What is the minimum order quantity? Can I order samples first?
A: Our standard MOQ is 100 pieces per model. Sample orders are welcome — you can order 1–2 pieces for testing before placing a bulk order.
Q: Can I customize the wheel color or bracket finish?
A: Yes! We offer full OEM/ODM customization. You can choose custom wheel colors, bracket finishes, and even branded packaging with your logo. Custom orders have their own MOQ — contact us for details.
Q: Will these casters scratch or leave marks on my floors?
A: Not at all. Our PU wheels are non-marking and floor-friendly. They roll smoothly and quietly on tile, concrete, vinyl, and other hard surfaces without leaving scuffs or stains.
Q: These have a threaded stem — how do I install them on my equipment?
A: Simply bolt the top plate onto the furniture base using the pre-drilled mounting holes. Bolt spacing and hole diameters are clearly marked in the spec table above. Use M4–M6 bolts — no special tools needed.
Q: How do I know this caster can handle my equipment's weight?
A: Each caster supports up to 40 kg individually. For a 4-caster setup, the total safe working load is around 140 kg (safety margin included). Always distribute weight evenly across all casters. If you're unsure, our team can help you pick the right model.
Q: What is the typical lead time for orders?
A: Sample orders ship within 3–5 business days. Standard bulk orders typically take 15–25 days, depending on quantity. Custom orders may take a bit longer — we'll confirm the exact timeline when you order.
