Frequently Asked Questions
What is the maximum weight this castor can support?
Each castor has a load capacity of 110kg. When using four castors together on a single piece of equipment, the maximum combined load capacity is 330kg. This rating accounts for uneven weight distribution and ensures reliable performance under typical operating conditions.
Is this castor suitable for outdoor use?
This castor is designed primarily for indoor applications. The rubber on polypropylene wheel and pressed steel construction perform optimally on smooth indoor surfaces such as concrete, tile, and sealed flooring. For outdoor or rough terrain applications, alternative castor specifications may be more appropriate.
How do I install this castor onto my equipment?
The castor features a 4-hole top plate mounting system. The plate measures 100mm × 85mm with hole centres at 60mm × 80mm and a 10mm hole diameter. Secure the castor to your equipment using appropriate bolts or screws through the four mounting holes, ensuring the plate sits flush against the mounting surface for optimal stability.
What type of flooring is this castor compatible with?
The black rubber on polypropylene wheel with 85 Shore A hardness is floor-friendly and suitable for a wide range of indoor surfaces including concrete, tile, vinyl, sealed wood, and epoxy flooring. The rubber tread provides excellent shock absorption and vibration reduction whilst protecting floor surfaces from marking or damage during operation.
