Leveling casters roll equipment into place, then lock it level on the same unit. Each caster has a built-in foot: turn the adjuster to lower it, and the foot takes the load off the wheel and holds the equipment still. Raise the foot again and the equipment rolls. One part does the work of a caster and a separate leveler.
Zambus is the exclusive distributor of CarryMaster leveling casters. The range covers five series, in stem and flange mounts, with published load ratings from 110 lbs to 3,307 lbs per caster. Bodies are die-cast aluminum (AC, ACT and ALC series) or zinc galvanized steel (ACP and APLC series).
| Series | Profile and duty | Mount | Load per caster | Wheel size |
|---|---|---|---|---|
| AC Series | Standard height, light to medium duty | Stem (S) or flange (F) | 110 to 3,307 lbs | 1.65 to 3.62 in |
| ACP Series | Low profile, light duty | Stem (S) or flange (F) | 441 lbs | 1.97 in |
| ACT Series | Low profile, twin wheel, medium duty | Stem (S) or flange (F) | 441 to 882 lbs | 1.97 in (ACT-400) |
| APLC Series | Long leveling foot, medium duty | Flange (F) only | 441 to 1,543 lbs | 1.97 to 2.83 in |
| ALC Series | Swivel leveling, wheel brake or twin wheel, medium duty | Flange (F) only | 2,205 lbs | 2 to 3 in |
The ACT's twin wheels turn more easily in tight corners. The ALC-1000FB is the only CarryMaster leveling caster with a wheel brake, which can hold the wheel while the equipment is being positioned, before the feet are lowered.

A. Most problems come from how the casters are used, not from the casters themselves. Rolling equipment with the feet still down drags them across the floor, so raise every foot fully before moving. Small wheels stop at cracks, cords and debris, so clear the path first.
If the equipment still rocks once it is parked, one foot is not carrying its share: lower that corner until every foot bears weight and the wheels sit just clear of the floor. If a caster struggles under the load, compare the real load per caster with its rating, as covered in our guide to caster wheel load capacity.
A. We are not aware of a US regulation written specifically for leveling casters. The caster industry's trade body, the Institute of Caster and Wheel Manufacturers (ICWM), publishes test standards for casters and wheels in general.
What Zambus publishes for every CarryMaster model is its load rating per caster, shown on each product page. If your project needs supporting documentation, call us before you order so we can tell you what is available for that model.
A. For hospital beds and patient carts, Zambus carries CarryMaster casters in the Medical Plastic Casters category, including braked models, rather than leveling casters.
Leveling casters suit medical and laboratory equipment that stays parked in one spot for long periods. For beds, our guide on how to choose hospital bed casters covers braking, load capacity and cleanability.
A. The letters name the series and the last letter names the mount: S is a stem mount and F is a flange mount, so an AC-300S and an AC-300F are the same series fitted in different ways.
The number is a model designation, not the load rating. The AC-600S is rated 1,103 lbs per caster and the AC-1800F 3,307 lbs per caster. Always size from the load per caster shown on the product page, never from the model number.
A. In the CarryMaster range, the heaviest stem-mount leveling caster is the AC-1300S, rated 2,205 lbs per caster.
Above that, the AC-1800F carries 3,307 lbs per caster, the top of the range, and it is made with a flange mount only. If your load per caster is above 2,205 lbs, plan for a mounting plate on the frame.
A. Yes, as replacement wheels. The standard CarryMaster wheel is black PA6, and Wheels and Parts sells replacement wheels in PA6, MC nylon and anti-static polyurethane for the AC, ACP, ACT-400, APLC and ACTM-400.
The 3.62 inch wheel for the AC-1800F comes in MC nylon only, so check the fit table or call us with the model number before you order.
A. Yes. CarryMaster lists frames built from aluminum profile among the uses for its AC and APLC series.
Flange models bolt to a plate fixed to the frame, and stem models thread into a fitting at the end of the profile. Before ordering, check the stem thread or the plate hole pattern on the product page against your frame hardware.
A. Choose a low-profile caster when the equipment has to sit close to the floor. CarryMaster recommends its low-profile ACP and ACT series for ATMs and other financial equipment, and for communication equipment.
A lower caster keeps the overall height of the equipment down and lowers its center of gravity, which matters for tall, narrow cabinets.
A. Yes. CarryMaster leveling casters are priced and sold per caster, so you can order a set of four, a single replacement, or a larger quantity for several machines.
The leveling casters we carry are stocked in our New Jersey warehouse, and most orders ship within 24 hours.
A. Have four things ready: the total weight of the equipment including what it carries, how many casters it will stand on, how the casters attach (stem thread size or plate hole pattern), and the floor it will roll on.
With those, our Casters and Wheels Experts at (973) 777-4922 can match a CarryMaster series and model to your equipment.
