Medium Heavy Duty Steel Polyurethane Static Trolley Caster Wheel Orange 4 5 6 8 Inch Swivel Brake Double Ball Bearings

Our medium‑heavy‑duty orange PU caster wheel is engineered for demanding industrial and commercial material‑handling scenarios. Combining high‑performance polyurethane tread, reinforced stamped steel bracket and full‑total lock brake system, this caster delivers stable load‑bearing, ultra‑smooth rolling and long service life. Widely fitted on work trolleys, tool carts, warehouse storage racks, industrial cabinets, workshop machinery and logistics transport equipment. The bright orange PU outer tread brings high visual recognition while offering excellent protection for various ground surfaces.

1. Orange PU Wheel Tread High‑resilience cast polyurethane material. Features outstanding abrasion resistance, tear resistance and compression resistance. It produces low rolling noise during movement, will not leave marks or scratch epoxy floors, tiles, marble, cement floors and wooden floors. The compact wheel core adopts reinforced structural design, effectively resisting impact when the cart bumps.
2. Chrome‑Plated Steel Bracket & Yoke Heavy‑gauge stamped steel construction with bright chrome‑plated surface treatment. Great anti‑rust and anti‑corrosion performance, suitable for ordinary workshop, warehouse and indoor‑semi‑outdoor working environments. Thickened steel sheet improves deformation resistance under heavy load, avoiding bracket bending under long‑time loading.
3. Precision Swivel Bearing Built‑in precision ball bearing for 360‑degree free swivel. Steering remains light and flexible even under full rated load, saving manpower when turning and moving heavy equipment.
4. Total Lock Brake System Dual‑action total lock brake pedal. When stepped down, it locks both wheel rotation and swivel rotation at the same time. Effectively prevents equipment from sliding or turning accidentally. The brake pedal is thickened for durable repeated on‑off operation. Easy foot‑operated control, no extra tools required.
5. Flat Top Mounting Plate Standard flat square mounting plate with pre‑punch mounting holes. Provides firm installation connection. Easy to bolt onto cart frames, rack bases and equipment bottom frames for fast assembly.
