3 Inch Swivel Brake Caster Wheels for Trolley Programmes
Our 3 inch swivel brake caster wheels are a starting point for compact manually pushed trolleys, service carts and workshop storage equipment. This page is intended for importers and equipment makers specifying a coordinated set, including the required quantities of fixed, swivel and braked assemblies.
Qingdao Gleam Hardwares helps define a manageable product range: consistent mounting patterns, clearly labelled brake variants and packaging that distinguishes each SKU. These details support simpler receiving, assembly and replenishment.
| Specification | Selection details |
|---|---|
| Product focus | 75mm wheel / nominal 3-inch compact trolley caster. |
| Wheel construction | Black rubber tread and metal hub; tread width, hub length and bearing selected together. |
| Set arrangement | Provide the number of fixed, swivel and braked casters per trolley. |
| Installation | Specify top-plate dimensions and bolt centres, or send the alternative mounting drawing. |
| Brake selection | Define pedal location and required wheel-lock or total-lock function. |
| Load and travel | Quote the trolley’s empty weight, payload, caster positions, floor transitions and manual travel conditions. |
| Acceptance checks | Mounting dimensions, assembled height, rolling/swivel movement, brake operation and agreed assembly load test. |
| OEM packing | Model separation, carton quantities and identification labels established in the quotation. |
Plan a Repeatable Caster Set
Choose the trolley layout before comparing unit prices. Mixing casters with different installed heights can cause uneven contact, while inconsistent brake positions can make the trolley awkward to park. Keep the height and mounting reference consistent across the coordinated set.
For wholesale replenishment, identify the wheel diameter, fitting and brake type on the order line. A separate SKU for each configuration is easier for warehouse staff to select than one description covering every variant.
What Affects Your Landed Cost?
The useful comparison includes the wheel compound, hub and bearing, bracket construction, finish, assembly quality and carton configuration. An inexpensive wheel that requires fitting rework or arrives mixed with another mounting type can increase service costs. Ask for a sample and a written specification before committing to volume.
The 75mm size suits compact layouts where the application permits it. If thresholds or uneven travel surfaces dominate, compare a larger wheel and check frame clearance rather than assuming the same assembly will suit every trolley.
Buyer Questions
Is the catalogue load range a rating for this 75mm caster?
No. A range covering several diameters cannot be assigned to one caster. The quotation identifies the rating for the selected wheel, bearing and bracket assembly.
Can a waste bin use this caster?
Send the bin dimensions, loaded weight and travel surface for selection. A caster page does not establish suitability for a powered vehicle or garbage truck.
Where should I start for an existing replacement?
Use our 75mm rubber swivel caster replacement guide to prepare the mounting measurements. For larger trolleys compare the 160mm rubber swivel casters or browse the industrial caster category.
