NRH R9201-50A Swivel Caster – PP Black 70kg Load | Industrial Caster

NRH R9201-50A Swivel Caster - PP, Black, 70kg Load, 360° Maneuverability

The NRH R9201-50A is a high‑quality PP swivel caster designed for flexible, easy movement on industrial equipment, warehouse racks, and carts. Manufactured from durable polypropylene (PP) with a sleek black finish, it offers excellent resistance to impact, chemicals, and moisture. Each caster supports a 70kg bearing load, making it suitable for medium‑to‑heavy duty applications in workshops, factories, logistics, and warehousing. Weighing 180g, it delivers robust durability. The swivel bracket allows 360° rotation, enabling effortless direction changes and smooth maneuvering. The precision‑engineered mounting plate (refer to drawing for exact hole pattern) allows for easy, secure installation. Clear “NRH” branding and heritage since 1996 ensure quality and reliability.

As a product of NRH Box Hardware (specialist since 1996), this caster is manufactured under an ISO 9001 certified system. Regarding international compliance (ISO 9001, REACH, RoHS, SVHC), these standards can be supported based on customer requirements - contact us for details. OEM/ODM services are available for custom wheel materials, colors, or mounting plate dimensions. Full 2D/3D CAD models available upon request.

Key dimensions: refer to the engineering drawing for mounting hole spacing, wheel diameter, and overall height.

Why Choose a PP Swivel Caster?

Polypropylene (PP) is a lightweight, impact‑resistant thermoplastic that performs well in indoor industrial environments. Unlike rubber wheels, PP casters do not mark floors, resist oils and solvents, and roll smoothly over minor debris. The swivel design offers several key benefits:

• 360° maneuverability - change direction easily, ideal for tight spaces and complex paths
• Low rolling resistance - swivel bracket reduces pushing effort, lowering operator fatigue
• Versatile pairing - can be combined with rigid casters for controlled steering
• High load capacity - 70kg per caster for medium‑to‑heavy duty needs

Additional benefits: chemical/moisture resistance, non‑marking, quiet rolling, cost‑effective.

Primary Applications - Flexible Mobility (Wide Range of Use Cases)

• Industrial workbenches & assembly lines - mobile workstations easily repositioned between stations
• Warehouse shelving & material carts - light‑to‑medium duty storage racks, picking carts
• Medical carts & equipment stands - hospital medicine carts, instrument stands - easy maneuvering in corridors
• Commercial kitchen equipment & catering trolleys - mobile kitchen islands, food service carts
• Laboratory instrument carts - science lab mobile equipment, smooth and precise movement
• Display racks & promotional kiosks - temporary retail displays, easy repositioning
• Photography equipment carts - film set gear carts, maneuverable on uneven surfaces
• Small machinery bases (compressors, generators) - mobile bases for easy relocation
• Logistics sorting carts - warehouse picking carts, swivel casters boost efficiency
• Garden tool carts - greenhouse or garden center carts, flexible movement
• Vending machine bases - mobile bases for installation and servicing
• Office furniture - mobile filing cabinets, conference tables - easy layout adjustment
• Exhibition booth components - temporary modular displays, quick assembly

How It Works - Swivel Bracket, 360° Free Rotation

The NRH R9201-50A caster is designed for straightforward attachment to the underside of equipment. The top plate (with multiple mounting holes) is bolted or screwed to the chassis. The wheel rotates on a precision axle. The swivel bracket contains a bearing (ball or roller) that allows the wheel to independently rotate 360° around the vertical axis, enabling movement in any direction. Swivel casters provide excellent maneuverability and low push/pull resistance. In practice, swivel casters are often paired with rigid casters (e.g., two swivel casters at the front + two rigid casters at the rear) to achieve both flexibility and straight‑line stability. For four‑caster setups, the recommended total load capacity is calculated based on three casters (to account for uneven floors), giving a safe working load of 210kg (3 × 70kg).
