D&D Global Timing Belts
D&D Global (also known as D&D PowerDrive) is a manufacturer of industrial power transmission belts offering one of the broadest timing belt product lines in the market. D&D Global timing belts cover standard HTD curvilinear, imperial and metric trapezoidal, T-profile, AT-profile, and specialty S-tooth profiles. All standard profiles are manufactured to the same RMA/ISO and DIN dimensional standards as Gates, Continental, and Bando, making them direct dimensional replacements. Texas Belting stocks D&D Global timing belts for same-day shipping from Houston.

Metric Trapezoidal and AT-Profile
D&D Global manufactures T5, T10, AT5, AT10, and AT20 for European OEM equipment replacement. Direct dimensional replacements for Continental, Megadyne, and Optibelt at the same pitch and width specifications.
S-Tooth (Parabolic) Profile
D&D Global is one of the few manufacturers offering the S-tooth (sometimes called "parabolic" or "modified curvilinear") profile family. S-tooth belts use a parabolic tooth shape that provides improved load distribution compared to standard HTD, similar in concept to the Gates GT profile but available from D&D Global at S2M, S3M, S4.5M, S5M, S8M, and S14M pitches.
| S-Tooth Profile | Pitch | Comparable Standard Profile | Notes |
|---|---|---|---|
| S2M | 2 mm | GT2 2mm | Miniature precision drives, 3D printers, small robotics |
| S3M | 3 mm | 3M HTD | Small industrial drives, instruments |
| S4.5M | 4.5 mm | Between 3M and 5M | Specialty pitch. Used on specific OEM equipment. |
| S5M | 5 mm | 5M HTD | General industrial. Improved tooth shape vs standard 5M. |
| S8M | 8 mm | 8M HTD | Heavy duty. Improved load distribution vs standard 8M. |
| S14M | 14 mm | 14M HTD | Heaviest duty. Improved tooth profile. |

D&D part number format note: For HTD and imperial trapezoidal belts, D&D Global uses the same part number format as Gates and Bando (e.g., 390-5M-25, 300L075). For T-profile and AT-profile belts, D&D sometimes uses a different format: [width][profile]/[length]US (e.g., 16T5/1380US = T5 profile, 16mm wide, 1380mm length). Texas Belting can decode any D&D part number. Call 888-203-2358.
Why Choose D&D Global Timing Belts
- Broadest profile coverage of any single manufacturer. D&D Global covers HTD, imperial trapezoidal, T-profile, AT-profile, and S-tooth in one product line. Few other manufacturers offer this range.
- S-tooth exclusive. The S-tooth parabolic profile at S2M through S14M is a D&D Global product not available from Gates, Continental, or Bando. If your equipment specifies S-tooth, D&D is the source.
- Competitive pricing. D&D Global provides value pricing on standard profiles comparable to Diesel Belting and Bando.
- Same dimensional standards. All standard HTD, trapezoidal, T, and AT profiles conform to RMA/ISO and DIN standards. Direct replacements for Gates, Continental, and Bando at the same part numbers.
- Aramid (Kevlar) cord options. D&D Global offers select timing belts with aramid tensile cord for applications requiring higher flex life or chemical resistance beyond standard fiberglass cord.
Or call 888-203-2358. We cross-reference D&D Global to Gates, Continental, Bando, and Diesel Belting.

D&D Global Timing Belt FAQs
Yes, for all standard HTD (3M, 5M, 8M, 14M) and trapezoidal (MXL, XL, L, H, XH, XXH) profiles. D&D Global manufactures to the same RMA/ISO dimensional standards. The part numbers are the same. Gates-exclusive products like GT3 and Poly Chain GT Carbon do not have D&D equivalents, but D&D's S-tooth profile is a comparable performance upgrade over standard HTD.
S-tooth is D&D Global's parabolic tooth profile, available at S2M, S3M, S4.5M, S5M, S8M, and S14M pitches. The S-tooth shape provides improved load distribution compared to standard HTD, similar in concept to Gates GT. S-tooth belts are designed to run on standard HTD pulleys at the corresponding pitch. The S4.5M pitch (4.5 mm) is a D&D exclusive not available from other manufacturers.
Yes. D&D Global manufactures T5, T10, AT5, AT10, and AT20 for European OEM equipment. D&D uses a different part number format for these profiles (e.g., 16T5/1380US instead of T5-1380-16), but the belt dimensions are the same. Texas Belting can decode any D&D part number format.
For HTD and imperial trapezoidal, D&D uses the standard format (390-5M-25, 300L075). For T and AT profiles, D&D sometimes uses [width][profile]/[length]US format (e.g., 16T5/1380US = T5, 16mm wide, 1380mm). For S-tooth, the format is [width]-S[pitch]M-[length] (e.g., 250-S4.5M-360). Call 888-203-2358 with any D&D part number and we will decode and cross-reference it.
Yes. Texas Belting stocks D&D Global timing belts in popular HTD, trapezoidal, T-profile, AT-profile, and S-tooth sizes for same-day shipping from Houston. For sizes not in stock, we can source any D&D Global part number on short lead time. Call 888-203-2358 or request a quote online.
