Multi-Speed Belts
Explanation ofNumbering System
First two digits indicate top width in sixteenths of an inch.
Next two digits designate sheave angle in degrees that the belt is designed to fit. Last three or four digits indicate
pitch length to the nearest tenth of an inch.
Example: Belt No. 2326V310 designates: 23 26 V310
Top Width in 16ths of Sheave Angle in Multi-Speed Pitch Circumfrence to the an Inch: 23/16" = 1-7/16" Degrees (26) Nearest 10th Inch: 31.0"

number corresponds to first two digits
of Industry Standard Number.
For Example: 4L450. 2450 = 4L450 Belt length is to the nearest tenth of an inch.
Example belt is 45.0" O.C.

Made by joining two or more single V-belts with a permanent, high strength tie-band. PowerBand belts prevent turn-over or jumping off the sheave problems associated with heavy shock-loads on individual belts. PowerBand belts use the same system of size and length designation as individual belts.
The same 3V, 3VX, 5V, 5VX & 8V sections are available as in single Super HC & Super HC Molded Notch belts. 3VX & 5VX PB available in Vextra construction.
The same A, B, C & D sections are available as in single Hi-Power II belts. A section PowerBand belts may be made to order.
Aramid tensile cords provide superior service on high impact, shock-loaded drives. Available in selected sizes of Super HC and Hi-Power II belts.

All synchronous belts are identified in a similar manner, in either English or metric units. Belts are measured by:
1.
Pitch: Distance in inches or millimeters between two adjacent tooth centers as measured on the belt pitch line.
2.
Pitch Length: Total length (circumference) in inches or millimeters as measured along the pitch line. It is equal to the pitch multiplied by the number of teeth in the belt.
3.
Width: Always shown as the last part of the size designation. Denotes width in inches or millimeters.
Available in 8mm and 14mm pitches.
8mm widths include: 12mm, 21mm, 36mm, 62mm;
Examples: 8MGT-640-12 Belt 8MX-22S-12 1008 GT2 Sprocket 14mm widths include: 20mm, 37mm, 68mm, 90mm, 125mm
