Why you can rely on us

Frequently asked questions

What do Ld, Lw and La mean?

Ld and Lw are the pitch length along the neutral line: ISO writes Ld, DIN writes Lw, the number is the same. La is the outside length along the back; for SPA it is 18 mm more. This belt has Ld 3350 mm and La 3368 mm.

Can I fit SPAX or XPA 3350?

The size and groove are the same; a belt with the letter X has a cogged underside and bends more easily on small pulleys. You can fit it, but belts of one drive should be of one brand and one design.

How do I measure an old belt if the number has worn off?

The top width of SPA is 12.7 mm and the height is 10 mm. A tape measure along the back gives the outside length La; subtract 18 mm to get the number in the part number.
