What This Model Is
The CT4041 is a best selling model from the Qingdao Renwei catalogue. The source catalogue lists the ct4041 medium duty caster among Renwei's most popular products but publishes no dimensioned specification for it, so the table below shows TBC rather than estimated figures. Ask for the full specification of the ct4041 medium duty caster against a photograph of the model you want.
This model is listed in the source catalogue among Renwei's most popular products.
What the Specification Tells a Buyer
TPR wheel
A softer wheel material runs quieter and protects finished floors, at the cost of some capacity.
Fitted height published
Overall height is listed as 68/97/132/155mm across the diameters offered, so a replacement can be chosen without changing the working height of the equipment.
Matched spares from the same catalogue
Wheels, casters and tubes are published here as their own models with their own specifications, so a worn part can be ordered by model number instead of described over email.

CT4041 Medium Duty Caster Questions
What load is the CT4041 rated for?
The source catalogue publishes 70/100/125/140kg for this model. It is a per-model figure, so use it rather than a figure quoted for the The Most Popular Products range as a whole.
What is the minimum order quantity and lead time?
Neither is published on the source site, so neither is stated here. Send this model number with the quantity you are considering and ask for both in writing before you plan a shipment.
Are certificates or test reports available for the CT4041?
The source site publishes no certification list, so none is claimed on this page. Request the specific certificates your market requires and ask for them in writing before ordering.
