The ZS series of heavy-duty wheels and castors by LAG are used to move heavy loads. Therefore, they have a much sturdier design and are under certain circumstances suitable for higher travelling speeds. These castors ensure safe and permanent mobility, for example, for storage and industrial trucks as well as for special assembly and transport systems.

• Cast soft polyurethane coating, hardness 87±3 Shore A
• Core in cast iron painted
• High load capacity, smooth and noiseless running; high resistance to abrasion, wear and tear, oils and greases; shock absorbing
• Temperature range: -30°C / +80°C (-22°F / +176°F)
• Hub with: shielded precision ball bearings
• Heavy gauge top plate
• Thermoplastic dust protection ring
• Swivel fork and dust cover in pressed steel sheet
• Tapered roller bearing

Polyurethane tyred wheels have high tear strength and abrasion resistance which gives them a life of up to 10 times that of rubber under similar operating conditions. Polyurethane is able to carry loads approaching that of cast iron. Polyurethane has a lower tractive resistance than rubber for the same load so is better for manual handling of very heavy loads. Polyurethane is not affected by greases and mineral oils.
