Heavy Duty Castors and Wheels

Be sure you know what's carrying your load

Not all heavy duty castors and wheels are the same, and differences can be critical. Keystone stock a wide range of heavy duty castors from the Industry Standard Revvo H Series with premium Polyurethane tyred wheels to Flexello's ISO Tow Caster sets that enables ISO Freight Containers weighing up to 12 tonne to be moved quickly and easily without expensive equipment.

Keystone Castors stocks ranges of heavy duty castors and wheels to suit various price / quality combinations as required by the application: from non-critical applications right through to high performance, critical applications: Be sure you know what's carrying your load.

Polyurethane Tyres

The most popular 'tyred' wheel used in heavy duty applications is polyurethane. This is because it is kinder to floors than solid wheels (such as cast iron wheels or Nylon wheels) under heavy load. The load capacity of quality polyurethane is typically three times higher than rubber tyres, which means that smaller diameter wheels can be used if required. But, not all polyurethanes are the same and they differ in compostion and properties.

H Series

Revvo 'H' series is a well-established, industry standard heavy gauge forge steel castor with hardened ball race swivel heads that serve as both thrust and radial bearings. This castor comes supplied with nylon seals and hydraulic grease nipple to make maintenance easy. The closed base of the swivel ring prevents downward escape of lubricant and completes grease reservoir. Sideplates are press formed to a cylindrical shape to give the best strength to weight ratio and are continuously welded to the swivel ring.

  • Load capacity to 1500kg

 

       

 

2SH and 2HF Series Twin Wheels:

Ths is a twin wheel version of the standard H series and offer a larger footprint and easier turning due to differential action of the wheels. Offering low overall height the range features hardened ball race swivel heads, serving as both thrust and radial bearings. Twin wheel 2SH castors are supplied with metal swivel seals as standard. Hydraulic grease nipple on swivel ring allows ease of maintenance. The closed base of the swivel ring prevents downward escape of lubricant and completes grease reservoir.
