125mm PU Caster Wheels Yellow Heavy Duty Polyurethane Casters

125mm Yellow PU Material Fix Caster Wheel - Easy Assembling For Equipment

Features

• Core Material: The wheel center is typically constructed from heavy-duty materials like cast iron or aluminum , providing a rigid and durable foundation that resists deformation under load .
• Tread Material: The tread is made from high-performance polyurethane (PU) , which is known for its durability and floor-protective properties .
• Bearing Type: These wheels commonly feature precision ball bearings (sometimes double ball bearings ), which ensure smooth rolling and reduce the effort required to start moving .
• Load Capacity: A 125mm PU fixed caster wheel typically has a high load capacity, generally ranging from 400kg to 450kg for standard heavy-duty models . Some specialized wheels can handle up to 1000kg .
• Key Properties: PU treads are non-marking and gentle on floors . They offer excellent resistance to abrasion, tearing, compression, and many chemicals like oils, greases, and solvents.

Function

1. Provides Straight-Line Mobility: As a fixed (rigid) caster, its primary function is to allow equipment to be moved in a straight line. It is typically used in pairs with swivel casters to provide directionally stable movement .
2. Supports Heavy Loads Safely: The robust construction, combining a strong metal core and durable PU tread, is designed to bear significant weight while maintaining a low rolling resistance for easy maneuverability .
3. Ensures Smooth, Quiet Operation: The polyurethane tread absorbs micro-vibrations from the floor surface, resulting in much quieter operation compared to hard wheels like steel or nylon .
4. Protects Flooring and Equipment: The non-marking nature of PU prevents scuffs and skid marks on floors, while its shock-absorbing qualities protect the wheel and the equipment's load from impacts.

Ideal Applications

This type of caster is a versatile solution for a wide range of commercial and light industrial settings where floor protection and smooth movement are important.

1. Material Handling & Logistics: Perfect for towline carts, heavy-duty trolleys, and dollies in sorting centers and warehouses that need to withstand frequent impacts and high-speed movement .
2. Commercial Environments: Ideal for applications in retail, hotels, and institutions on equipment like service carts, display units, and laundry trolleys where quiet operation and floor care are essential .
3. Assembly and Manufacturing: Suitable for mobile engine stands, machine tool platforms, and workstations on workshop floors, offering high load capacity and resistance to industrial oils and greases .
4. Specialized Applications: Can be used on automated guided vehicles (AGVs) as support wheels or on mobile scaffolding and compressors that navigate rougher surfaces .
