Heavy Duty Casters in Nylon and PU
100 to 200mm wheels rated 200kg and up — where light duty stops being honest.
Heavy Caster Models
Capacity and diameter are published as parallel lists, so 100/125/150/200 diameter against 200/280/350/450 capacity means the 200mm wheel carries 450kg.

About This Family
Heavy duty casters are where wheel material stops being about noise and starts being about whether the wheel survives. Nylon and PP carry the most on smooth floors; PU carries less but protects the floor and grips better.
This range publishes wheel material, diameter, width, overall height and capacity for every model, with the capacity given per diameter rather than as a single headline number.
What Goes Wrong Without the Right Heavy Duty Caster
Problem 1
Equipment specified on a headline capacity that only applies to the largest wheel in the family.
Problem 2
Nylon wheels on an uneven floor that transmit every joint into the load and the operator.
Problem 3
Casters that swivel well when new and seize within a year because the raceway was never suited to the load.
Buyers This Family Is Built Around
Industrial equipment builders
Machine bases, tooling carts and heavy fixtures.
Warehouse and logistics operators
Cages, dollies and transfer trolleys in constant use.
Plant maintenance teams
Re-wheeling equipment as loads or floors change.
What the Published Specification Gives You
Capacity published per wheel diameter
Four diameters and four ratings are published together so the caster can be specified honestly.
PP, PA and PU options
Material can be chosen for load, floor protection or rolling effort rather than accepting one compromise.
Overall height published for every diameter
Fitted height is given per diameter, which matters when equipment must clear a doorway or sit at a set height.
Consistent bracket family
Fixed, swivel and braked variants share the family, so a set can be mixed across one item of equipment.
Where These Are Used
Transfer and tooling carts
Heavy work in progress across a plant.
Roll cages and dollies
High-cycle logistics use.
Machine and equipment bases
Machines repositioned for maintenance or line changes.
Storage and racking modules
Mobile storage inside buildings.
How to Choose Within This Family
- Read the diameter and capacity rows together; the headline figure belongs to the largest wheel only.
- On rough or jointed floors, go up a diameter before going up in material hardness — diameter does more for rolling effort than hardness does.
- Specify at least one braked caster per item of equipment if the floor is not dead level.
What is not published
Minimum order quantity, lead time, payment terms, warranty and certifications are not published by Renwei, so none of them are stated on this site. Ask for them in writing with your model list before you plan a shipment.

Heavy Caster Questions
What capacity do heavy duty casters carry?
Capacity is published per wheel diameter. A typical PP/PA model in this range is listed at 200, 280, 350 and 450kg for the 100, 125, 150 and 200mm wheels respectively.
Should I choose nylon or polyurethane?
Nylon and PP carry more per wheel and roll easily on smooth hard floors, but they transmit shock and can mark. Polyurethane carries less, grips better, runs quieter and protects the floor.
What is the overall height of the caster?
Overall height is published for every wheel diameter in the range, so the fitted height can be checked before ordering.
Can we get these with a brake or a directional lock?
Brake and lock variants are not published per model in the source catalogue. Send the model number and what you need and ask for confirmation.
