Z section is the smallest common metric classical V-belt: 10mm top width by 6mm deep. Texas Belting & Supply stocks 64 Megadyne Z section belts in lengths from 12 to 84 inches for fractional-horsepower and light-duty drives, replacing Jason Industrial Z section part numbers directly.
Z Section Applications and Equivalents
Z section drives small equipment: power tools, appliances, lab and shop machinery, and light HVAC drives. Dimensionally it sits close to the imperial 3L section (3/8") and below A section (1/2"); SPZ is its narrow-wedge metric counterpart. Match the section stamped on your old belt or measure the top width of the pulley groove.
Frequently Asked Questions
What size is a Z section V-belt?
Z section measures 10mm (about 3/8 inch) across the top and 6mm deep with a 40-degree angle. It is the smallest standard metric classical section.
Is Z section the same as 3L?
They are close but not identical. Z is the 10mm metric section; 3L is the 3/8 inch imperial FHP section. In many light drives they interchange, but match the original section when possible.
Do Megadyne Z belts replace Jason Industrial Z belts?
Yes. Jason Industrial V-belts are now manufactured under the Megadyne brand, and part numbers carry over unchanged.
