The best small wheels for a trolley depend on its mounting style, load, and intended surface. For general-purpose rolling, the 2-inch polyurethane set offers a stated 450-pound combined capacity and brakes. For very compact builds, consider the 1-inch rubber or PP casters, while the 1.5-inch rubber wheels suit buyers who need a simple replacement wheel. A separate strut-channel roller is designed for a specific overhead track, not a typical trolley base.

| uxcell 1.5-inch rubber wheels | Basic wheel replacements | Four rubber wheels per pack |
2-Inch PU Casters With Brakes
This set is best for buyers who want compact swivel casters for a trolley, workbench, shelf, or furniture base and need a higher stated load capacity. The listing specifies four 2-inch polyurethane wheels, mounting screws, washers, and a combined capacity of 450 pounds across all four casters.
Double ball bearings are listed to support smooth rolling. The product name identifies the casters as locking, and the listed features refer to brakes. Choose this set when braking is important and the plate mounting suits the trolley. The stated capacity is for the set, not each wheel; do not treat 450 pounds as a per-caster rating.
1-Inch Rubber Casters, 12-Pack
These 1-inch swivel casters are best for lightweight trolleys and compact projects where a rubber wheel and a larger quantity are useful. The listing gives a wheel diameter of 25 mm, a width of 11.8 mm, and a capacity of 11 pounds per wheel. It describes metal construction with a rubber base, precision ball bearings, and quiet rolling across surfaces such as tile, wood, carpet, and concrete.
Choose this option when the trolley’s load can be distributed within the per-wheel limit and the top-plate mounting matches. The key limitation is capacity: 11 pounds per wheel is modest, and the listing does not state a combined trolley rating.
Maitys 1-Inch PP Casters, 12-Pack
Choose these compact polypropylene casters for a project that needs multiple small wheels and included mounting screws. The package contains 12 wheels and 48 screws. Each wheel is about 1 inch, and the listing states a total weight capacity of approximately 30 kg, or 33 pounds. The wheels have a PP body and metal top plate.
This set is best for furniture, appliances, or a small trolley when the mounting dimensions and total load fit the application. Its large quantity can also suit multi-piece projects. Avoid choosing it for a heavy trolley: the stated capacity is 33 pounds total, not 33 pounds per wheel.
Four-Wheel Strut-Channel Trolley Rollers
These rollers are best for a trolley or carriage designed to run inside a compatible strut-channel track. The listing specifies compatibility with a 1-5/8-inch-wide by 1-5/8-inch-high channel and identifies overhead doors, garages, warehouses, and industrial rails as intended settings. The two-piece product uses 304 stainless steel and four precision bearings per roller.
The four-wheel layout is described as improving balance and reducing shaking compared with two-wheel trolleys. This is not a general-purpose plate-mount caster: choose it only if the channel dimensions and track arrangement match. The listing provides no load-capacity figure, so verify capacity before using it for a loaded trolley.
uxcell 1.5-Inch Rubber Wheels
This four-piece set is best for buyers looking for 1.5-inch rubber wheels as replacement components or for a simple trolley project. The listing identifies the material as rubber, the color as black, and the package quantity as four. Its concise specifications make it useful when wheel material and diameter are the main selection criteria.
Check how the wheel attaches to the trolley before ordering. The provided features do not specify a mounting plate, axle dimensions, swivel function, or load capacity. Avoid relying on these wheels for a particular load or mounting arrangement unless those details are confirmed for your application.
Buying Guide: How To Choose Small Trolley Wheels
What wheel diameter fits the trolley?
Measure the available clearance beneath the trolley and around its frame. The options here range from 1-inch casters to 2-inch casters, with a separate 1.5-inch rubber wheel. A smaller diameter can fit a compact base, but clearance alone is not enough: also check the wheel width, mounting plate, axle, and space needed for swivel movement.
How much weight must the wheels support?
Use the capacity stated for the exact product and determine whether it applies per wheel or to the whole set. The 2-inch set lists 450 pounds total for four casters; the 1-inch rubber casters list 11 pounds per wheel; and the Maitys set lists about 33 pounds total. Leave room for uneven weight distribution and do not compare these figures as though they use the same rating basis.
Should you choose rubber, polyurethane, or PP?
Material can influence the intended use, but the listed details do not provide a direct performance comparison across all three types. The rubber-base 1-inch casters are described as quiet, and the 2-inch wheels are polyurethane. The Maitys wheels use PP. Match the listed material and features to the floor, noise needs, and trolley design rather than assuming every material behaves identically.
Do you need swivel casters, brakes, or track rollers?
Swivel casters turn to help a trolley change direction. A brake can help keep a trolley from moving when parked, while a channel roller is made for a compatible track. Confirm the mounting method and track dimensions before buying. The strut-channel rollers listed here are for a specified 1-5/8-inch channel, not a standard plate-mount setup.
Frequently Asked Questions
What size are small trolley wheels?
Small trolley wheels in this selection measure 1 inch, 1.5 inches, or 2 inches in diameter. The right size depends on frame clearance, mounting style, and required capacity.
Are 1-inch wheels suitable for a heavy trolley?
Not necessarily. The 1-inch rubber casters are rated at 11 pounds per wheel, while the Maitys listing states about 33 pounds total. Check the specific capacity and trolley load before selecting small wheels.
Can these casters roll on different floor types?
The 1-inch rubber casters are listed for concrete, carpet, tile, wood, and slate. The other product listings do not provide the same range of floor information.
Are strut-channel rollers interchangeable with swivel casters?
No. Strut-channel rollers are designed to run in a specified channel track, while swivel casters mount to a trolley or other base. Confirm the product type matches the trolley design.
Do all products include mounting hardware?
The 2-inch PU set lists screws and washers, and the Maitys 12-pack lists 48 screws. The other product descriptions do not specify included mounting hardware in the provided features.
