Gates is an American maker of belts and hoses. The company was founded in 1911, is based in Denver and has sites in North and South America, Europe, Asia and Australia. From Gates we mainly offer V-belts for compressors, pumps and machines, plus two hoses: one for fuel and one for steam.
Our belts come in four types: classical belts to DIN 2215, narrow cogged belts to DIN 7753 in CR or EPDM rubber and multi-rib belts to ISO 9932. Every belt lists its profile and length, classical belts also their code, so you can easily match a replacement to your old belt.
Belts to DIN and ISOGates belts and hoses
Classical V-belts
The standard belt for compressors and pumps. SBR rubber with high-strength polyester cords, cross-section to DIN 2215.
- profiles Z, A, B and C
- lengths from 435 to 5770 mm
- working temperature −30 to +70 °C
Narrow cogged V-belts
A narrow profile with cogs. CR rubber with polyester cords, cross-section to DIN 7753.
- profiles SPZ and SPB
- SPZ from 560 to 2800 mm
- SPB from 1250 to 2500 mm
EPDM cogged V-belts
For heat and frost, no re-tensioning. Narrow cogged belts in EPDM rubber to DIN 7753, in a maintenance-free design.
- profiles XPZ, XPA and XPB
- temperature −50 to +130 °C
- no re-tensioning needed
Multi-rib belts
Several ribs on one belt. A flat CR rubber belt with polyester cords, profiles to ISO 9932.
- profiles PJ, PL and PM
- lengths from 508 to 9931 mm
- smooth running, easy tensioning
Fuel Profi fuel hose
Unpressurised hose for petrol and oils. A clear green hose in soft PVC, electrically conductive.
- meets EN 12115 and EN 1761
- sizes from 4/2 to 22/16 mm
- also for water, air and coolant emulsions
Looking for an air hose, hose clamps or a hose reel? Everything for air, water and other media lines is in the Hoses category.

How to choose and replace a belt
1. Find the profile and length
The marking is on the back of the old belt, for example A109 or SPZ 2800. Each of our belts lists its profile, length and cross-section.
2. Release the tension
Move the motor or tensioner so the belt can be fitted freely by hand. Do not lever the belt over the pulley rim, as this damages the cords.
3. Replace the whole set
On a drive with several belts, replace them all at once. A new belt next to stretched ones would carry most of the load.
4. Tension and check
Tension the belt as the machine manual says and check it again after a few hours of running. EPDM belts do not need re-tensioning.
Frequently asked questions
- How do I know which belt I need?
- By its profile and length. The profile is a letter or code (Z, A, B, C, SPZ, SPB, XPZ, XPA, XPB, PJ, PL, PM) and the length is in millimetres. For classical belts the code helps too, such as A109, which you will find in the parameters next to the length.
- What is the difference between a classical and a cogged belt?
- Classical belts have the traditional cross-section to DIN 2215. Cogged belts are narrow belts to DIN 7753, and the cogs on the inside help them bend around smaller pulleys.
- Which belt can take higher temperatures?
- EPDM belts (XPZ, XPA, XPB) work from −50 to +130 °C. Classical SBR belts are designed for −30 to +70 °C.
- What are multi-rib belts for?
- They have several ribs on one flat belt to ISO 9932. They are used on compressors, pumps, alternators and saws, run smoothly and are easy to tension.
- Which Gates hoses do you offer?
- Fuel Profi PVC is an unpressurised hose for petrol, oils, water and air. Steam Profi 210 is a rubber hose with two steel braids for saturated steam up to +210 °C and 18 bar, and it also suits pressurised hot water.
