Metric Timing Belt Nomenclature?

03/14/2009 11:38 PM

Folks, got a slight problem here--

Bought a nice lathe, a Central Machinery 8 x 10" engine lathe, and for one of the belts, they use a "syncronized tooth belt" with a spec of M1.5XZ18 ( I suspect it's more like M1.5 x Z118), and it's a crappy PRC-made belt that's on the verge of falling apart before it's used

Here's a site showing a photo of this belt;

So, I'm trying to find out the size specs on this so I can order up a DECENT belt, not this replacememt POS!

There are companies around the world that supply toothed belts. You need only to measure the width of the belt, the width of each tooth and dip (usually the same) and the total length and find the same in a catalog, Googlöe a supplier in your region, then simply order.

Also you can buy this stuff in almost any length and couple it if a loop is needed.....

Remove the belt before it completely falls apart. Go to any belt / bearing supplier and let them match it up. I use Tri- State Bearing and venture to say there are similar places in your area. As for the numbers on the belt I have found it routine to have incorrect information on belts from China that are original to the machine. For me it has been more of a problem on V-belts than timing belts. I have also found odd pitch size timing belts that force you back to the manufacturer just to be told they do use / make it anymore.

Good Luck

Sorry, the last line of my previous post should have been:

Hi Locksmith, These types of belts are known as cogged or synchronous belts. They have slots that run perpendicular to the belts length.Synchronous belts are also called Timing or positive- drive or high torque drive belts. We have been using OPTIBELT make for our lathes without much problem. For further details, you may visit www.optibelt.com Good luck. Rangasamy

Locksmith Al

Does the belt have a squared off or rounded tooth profile ?

Squared off for the most part.

Belt is 15 mm wide with 118 teeth, each "tooth" is 1.5 mm.
