Spare Parts and After Sales Support
On wheeled equipment the wheel fails first — so buy it as a line item, not as an emergency.
Almost every piece of equipment on this site fails in the same place: the wheel. Wheels are consumable, and a fleet that holds none is a fleet that scraps good frames.
Because Renwei publishes wheels and casters as their own models, spares can be ordered by part number rather than described over email.
How It Runs Step by Step
Identify the wheel on your equipment
Diameter, section, rim and bore. Photograph the wheel and the hub together.
Find the matching model
Wheels and casters are published as individual models in their own categories on this site.
Standardise where you can
One wheel size across a fleet cuts the spares holding more than any other single decision.
Hold a first stock
A small stock of the most common wheel keeps equipment in service through a season.
Rebuild rather than replace
Where the bracket is sound, a wheel-only replacement restores the caster at a fraction of the cost.
Re-order by part number
Once a size is established, repeat orders become a single line rather than a conversation.

Spare Parts and After Sales Questions
Can I buy replacement wheels without the cart?
Yes. Rubber wheels, PU foam wheels, EVA wheels and caster wheels are all published as separate models with their own specifications.
Do I need to replace the whole caster or just the wheel?
If the bracket and swivel are sound and only the wheel has worn, replace the wheel. If the swivel is notchy or the bracket is bent, replace the complete caster.
What warranty applies?
Warranty terms are not published on the source site. Ask for them in writing against the models you are ordering.
