The Carrymaster ACMM series is a medium-duty flange caster with a single MC nylon wheel, rated 1,433.00 to 1,763.70 lbs per caster. Its product pages list semiconductor equipment, electronic parts production facilities, laboratory equipment, chemical equipment and medical devices among its applications.
Zambus carries 11 ACMM models in four sizes, as rigid flange (RF) and swivel flange (SF) casters, with a braked swivel flange (SFB) in the 100, 125 and 150 sizes. Frames are zinc-galvanized S45C and SPHC steel on a zinc-galvanized SPC top plate.
| Size code | Load per caster | Wheel size | Brake version | Models (ACMM-) |
|---|---|---|---|---|
| 75 | 1,433.00 lbs | 2 to 3 in | No | 75RF, 75SF |
| 100 | 1,543.24 lbs | 3 to 4 in | Yes (SFB) | 100RF, 100SF, 100SFB |
| 125 | 1,653.47 lbs | 4 to 5 in | Yes (SFB) | 125RF, 125SF, 125SFB |
| 150 | 1,763.70 lbs | Over 5 in | Yes (SFB) | 150RF, 150SF, 150SFB |
Within each size, the rigid, swivel and braked models carry the same rating. Weights run from 2.65 lb (ACMM-75RF) to 5.29 lb (ACMM-150SF and ACMM-150SFB). All models use 0.43 in mounting holes; full dimensions are on each product page.
ACMM, then the size code (75, 100, 125 or 150), then the mount: RF rigid flange, SF swivel flange. A trailing B is the braked version, so an ACMM-125SFB is a size 125 swivel flange caster with a brake.

A. The ACMM series banner shows the SFB brake as a ring-pull pin at the side of the wheel, and the product pages list the brake part as zinc. They do not describe what the brake locks beyond that.
If your application depends on how the brake holds, call us at (973) 777-4922 with the model number before you order.
A. The 100, 125 and 150 sizes, each as a braked swivel flange model: the ACMM-100SFB, ACMM-125SFB and ACMM-150SFB.
The ACMM-75 comes as a rigid flange and a swivel flange only, with no braked version.
A. The ACMM-150RF, rated 1,763.70 lbs per caster. The ACMM rigid models run from 1,433.00 lbs (ACMM-75RF) up to that figure.
Below the ACMM, the ACMU rigid models are rated 881.85 to 1,212.54 lbs.
A. Both come in the 75, 100, 125 and 150 sizes with rigid and swivel flange models and share the same frame and top plate materials. The ACMM has an MC nylon wheel and is rated 1,433.00 to 1,763.70 lbs; the ACMU has a polyurethane wheel on an aluminum core and is rated 881.85 to 1,212.54 lbs.
Only the ACMM offers a braked model.
A. The ACM is rated 1,764 or 2,205 lbs per caster, has a die-cast aluminum frame and a PA6 wheel, and is swivel only.
The ACMM tops out at 1,763.70 lbs, has a zinc-galvanized steel frame and an MC nylon wheel, and adds rigid models.
A. Semiconductor equipment and laboratory equipment are among the listed ACMM applications, but the product pages do not list a cleanroom class or an ESD rating.
For cleanroom projects, read our guide to cleanroom and semiconductor equipment casters and call us with the requirement before you order.
A. No. All 11 ACMM models are flange mount only.
In the non-leveling range, stem mounts are offered only on the lighter ACSU and ACLU series.
A. No. The MC nylon wheels in our Wheels and Parts category are listed for the AC, ACP, ACT, APLC and ACTM casters, not for the ACMM.
If an ACMM wheel is worn, replace the caster, or call us to check your model.
A. That is the SKU. It drops the hyphen and pads with zeros to 11 characters, so ACMM-125SFB is ACMM0125SFB and ACMM-75RF is ACMM00075RF.
Both codes refer to the same caster, so you can reorder from either one.
A. By load, all four sizes are in 1,000 to 2,000 lbs.
By wheel size, the ACMM-75 is in 2 to 3 in, the ACMM-100 in 3 to 4 in, the ACMM-125 in 4 to 5 in and the ACMM-150 in over 5 in.
