TPR Caster Wheels

Qingdao Gleam Hardwares supplies TPR caster wheels for equipment OEMs, hardware importers and trolley manufacturers. This thermoplastic rubber range is positioned for buyers who value quiet movement, resilient floor contact and a well-matched load specification. It serves hotel service carts, instrument equipment, commercial furniture, flight cases and everyday industrial trolleys according to the operating requirements and budget.

Choose the configuration by its job: free-swivelling travel, a defined brake function, fixed-direction tracking, a custom threaded interface, a replacement wheel or a coordinated case set. Casters and castors are alternative spellings; neither spelling changes the construction.

Common market dimensions can be produced. Special dimensions can be developed from a customer sample or drawing. Use the selection table to choose a starting point, then confirm mounting, installed height, bearing arrangement and the rated load of the complete quoted assembly.

Choose the TPR Configuration

Configuration	Primary purchasing task	Key information
Unbraked swivel plate casters	Quiet, frequently repositioned trolleys	Wheel size, plate pattern and bearing arrangement
Swivel casters with brake	Parking function for mobile equipment	Wheel brake versus dual locking; pedal clearance
Rigid plate casters	Straight tracking on flatbed carts	Travel direction and matching swivel height
Custom threaded-stem casters	M12 or drawing-matched mounting	Thread pitch, length, seating and retention
Replacement caster wheels	Wheel-only OEM or repair supply	Bore, hub length, width and bearings
Flight-case caster sets	Coordinated road-case rolling base	Layout, number of brakes and case reinforcement

Conventional Wheel Dimensions and Custom Production

Common trade size	Metric diameter to specify	Specification focus
2 inch	50 mm or exact imperial drawing	Compact wheels; confirm width, bore and mounting
2.5 inch	63 mm or exact imperial drawing	Small trolley and replacement interfaces
3 inch	75 mm or exact imperial drawing	75 × 32 mm is a common starting section
3.5 inch	90 mm or 88.9 mm as specified	Do not interchange these dimensions without checking fit
4 inch	100 mm or exact imperial drawing	100 × 32 mm wheel and its mounting envelope
5 inch	125 mm or exact imperial drawing	125 × 32 mm wheel and its bearing/hub fit
6 inch family	150, 152.4 or 160 mm as specified	Distinct actual diameters; approve the drawing
8 inch	200 mm or exact imperial drawing	Larger wheel section and assembly load review

These are production starting points and commercial size references, not a shared load table or a statement of stock. Width, axle bore, hub length, top-plate dimensions, hole centres, thread, brake and installed height are defined for the selected assembly. Special wheel sections and interfaces can be matched to a sample or drawing.

A Quieter Wheel, with Load and Budget Considered Together

TPR is often selected where rolling sound, floor contact and user experience justify a more considered specification. Medium-duty, middle-duty and heavy-duty are purchasing descriptions, not universal load standards. A high-load TPR project needs a suitable tread, core, bearing, fork and mount. Blue or black colour alone does not identify the compound or capacity.

PU/polyurethane, nylon, hard rubber and cast-iron-core wheels remain separate alternatives for different working conditions and budgets. If comparing wholesale supply or an OEM sourcing programme, keep material, load target, dimensions, quantity and packing scope consistent across quotations. See the existing caster material guide for the broader comparison and OEM caster supply programme for mixed-material projects.

Sourcing TPR Casters from China

For a manufacturer or wholesale enquiry, send the configuration, dimensional drawing, working-load target and quantity by model. If your sourcing policy requires factory-direct supply, include that requirement in the enquiry and ask for the production scope, sample-approval process and quality records. Furniture-component importers and equipment OEMs can use the same brief to compare suppliers on equivalent terms.

TPR Buying Guides

Quiet TPR casters for hotel, medical-support and equipment trolleys — define noise, floors, cleaning and budget priorities.
TPR caster sizes and load-capacity selection — measure the interface and prepare an assembly-specific load request.
Flight-case caster mounting and brake layouts — distinguish plate, corner and recessed constructions.

Request a Configuration-Matched Quotation

Send the required configuration, dimensions, mounting drawing or sample, loaded equipment weight, working route and quantity. Indicate whether the quotation should cover complete casters, replacement wheels or matched sets.
