Light Duty Casters for Trolleys Racks and Furniture
50 to 125mm wheels under equipment that moves daily and must not mark the floor.
Light Heavy Caster Models
Wheel diameter, overall height and capacity are published as parallel lists — 75/100/125 diameter against 50/70/100 capacity means each diameter has its own rating.

About This Family
Light duty casters carry the everyday load: shelf trolleys, racks, display units, workshop furniture. The specification that matters is wheel material, because that is what decides floor marking, noise and rolling effort.
This range publishes wheel material, wheel diameter, wheel width, overall height and capacity per model, which is the full set needed to specify a caster properly.
What Goes Wrong Without the Right Light Duty Caster
Problem 1
Hard nylon wheels chosen on price that then mark every vinyl and epoxy floor in the building.
Problem 2
Casters specified at the total load rather than per wheel, so they run permanently overloaded.
Problem 3
Overall height ignored, so the new caster changes the working height of a bench.
Buyers This Family Is Built Around
Furniture and fixture manufacturers
Casters under retail displays, office furniture and racking.
Trolley and cart assemblers
Light equipment produced in volume with a consistent caster programme.
Facilities and maintenance
Re-wheeling existing equipment to suit a new floor.
What the Published Specification Gives You
Capacity published against each wheel diameter
The rating changes with diameter, and this range publishes them together rather than quoting one headline figure.
Several wheel materials in one family
TPR, PU, rubber and nylon options let one bracket serve quiet indoor floors and rougher service areas.
Overall height published
Fitted height is given so a replacement does not change the height of the equipment it goes under.
Wheel width stated
Width affects both load spreading and how the wheel behaves on floor joints.
Where These Are Used
Shelf and service trolleys
Daily rounds on smooth indoor floors.
Retail display units
Fixtures moved for cleaning and reset.
Office and workshop furniture
Pedestals, benches and cabinets.
Light racking and cages
Stock movement inside a building.
How to Choose Within This Family
- Divide the total load by three, not four — on an uneven floor, three casters carry the load at any moment.
- Choose TPR or PU for quiet, non-marking service on finished floors; nylon only where floors are rough and loads are dragged.
- Match overall height when replacing, or the equipment changes working height and may no longer sit 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.

Light Heavy Caster Questions
How do I work out the caster capacity I need?
Take the total loaded weight, divide by three rather than four to allow for uneven floors, and add a margin for shock loading. Then pick a caster whose published capacity at your chosen wheel diameter exceeds that figure.
Which wheel material will not mark my floor?
Polyurethane and TPR are the non-marking choices for finished floors. Hard nylon and cast iron carry more but will mark vinyl, epoxy and timber.
Do the capacities apply to every wheel diameter?
No. The capacity list runs in parallel with the diameter list — the first capacity belongs to the first diameter, and so on. Read the two rows together.
Are braked versions available?
Brake fitment is not published per model in the source catalogue. Ask for braked versions against the model number you are quoting.
