Basic Information    Metric pitch timing belts mate with same-pitch timing pulleys in power transmission systems where maintenance-of-speed ratio is an important design consideration. Metric pitch is the distance between belt teeth based on millimeters (mm).    Function    With metric pitch timing belts, a timing pulley transmits force to the belt via evenly-spaced grooves that mate with the teeth in the belt. These same grooves and teeth prevent belt...

Applications and UseTop

Q:
What are some of the applications you have used metric pitch timing belts for?
26 answers
Answers:
Used 14m polychain to replace 4 x B section belts on 22kw motors; this reduced the radial load on motors as well as eliminating belt slippage on start up. Also have used 8m long length belt to actuate freezer doors

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of metric pitch timing belts?
4 answers
Answers:
Replacing polychain belt with standard HTD belts, running back idlers on generation 2 polychain. GT3 belts not fitting large diameter sprockets (running out of pitch).
~Mark B, Marketing/Sales, Palmerston North, New Zealand
Long belts without idlers or guides can either start dangerous or become worse over time as they age.
~Research & Development, Klamath Falls, OR
Yes - fitment of incorrect specification causing failure on non-free spooling motors.
~Carl K, Purchaser, Adelaide, Australia
The belt will break.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using metric pitch timing belts?
6 answers
Answers:
Read catalog & work designs around standard belt lengths rather than expecting a manufacturer to make a custom one for your application.
~Mark B, Marketing/Sales, Palmerston North, New Zealand
If you want reduced rolling resistance, do not over tighten.
~Research & Development, Mountain View, CA
Match Pulley profile with belt.
~Marketing/Sales, Loyang, Singapore
Check specifications
~Carl K, Purchaser, Adelaide, Australia
None at this time.
~Research & Development, Klamath Falls, OR
Better than chain.
