Frequently Asked Questions
What is the load capacity of this rubber castor wheel?
Each wheel is rated to carry up to 60 kg. For multi-wheel assemblies, the total load should be calculated across all wheels, ensuring no single wheel exceeds its rated capacity under dynamic or static conditions.
What does “plain bore” mean and what axle size does this wheel accept?
Plain bore means the centre hole is unlined and unground — there is no roller bearing or bush fitted. This wheel accepts an 8 mm axle or bolt. It is suited to low-speed applications where a precision bearing is not required.
Will this rubber wheel leave marks on wood, tile, or vinyl flooring?
The grey rubber compound used on this wheel is non-marking, making it safe for use on wood, laminate, tile, and vinyl floors. It is designed specifically to protect finished floor surfaces in retail, domestic, and light commercial environments.
What are the key dimensions I need to know before fitting this wheel?
The wheel has an overall diameter of 50 mm, a tread width of 22 mm, and a hub length of 27.5 mm. The bore (axle hole) measures 8 mm in diameter. Always verify these dimensions against your existing castor rig or frame before ordering.
Is this wheel suitable for outdoor surfaces or wet conditions?
This wheel is primarily intended for indoor, smooth-surface use. While the rubber material offers some moisture resistance, it is not rated for prolonged outdoor exposure, gravel, or uneven terrain. For outdoor or rough-surface applications, a harder compound wheel or a larger diameter may be more appropriate.
Can this wheel be used as a direct replacement for an existing castor wheel?
Yes, provided the existing rig accepts a wheel with a 50 mm diameter, 8 mm bore, and 27.5 mm hub length. Measure your current wheel and compare all three dimensions carefully. If your rig has a different bore size or hub clearance, an alternative specification may be required.
