Timing Belts & Pulleys

The three principal dimensions of Timing Belts are pitch length, pitch of the teeth and width for ordering code

XH Pitch 7/8

std width	code
2" 3" 4"	200 300 400

HIGH TORQUE BELTS

Ordering code: Pitch length in mm - Pitch in mm -width in mm
Example : 1778 - 14 M-85
Pitch length 1778 mm, Pitch 14 mm, Belt width 85 mm

3 M Standard Width 6mm, 9mm & 15mm	5M Standard Width 9mm, 15mm & 25mm

8 M Standard Width 20mm, 30mm, 50mm & 85mm	14M Standard Width 40mm, 55mm, 85mm, 115mm & 170mm

TIMING BELTS SIZES :

LIGHT PITCH PULLEY

(L) Pitch = 3/8" - L050/L075/L100

'H' Pitch = 1/2" - H100/H150/H200/H300

Belt width = H100 - 3/4" & 1", H150 - 1 1/2", H200 - 2", H300 - 3"

HEAVY(H) PITCH PULLEY

14M

	The number of flanges is given as either 0, 1 or 2. Should a pulley with hub, have only one flange, then it should be designated as follows: Flange on hub side (diagram left) - 1a Flange on the side opposite to the hub (diagram right) - 1g

PULLEY SELECTION SUGGESTIONS

• Pulley diameter should not be smaller than the belt's width.

• If centre distance is more than 8 times the diameter of smaller pulley, both the pulleys should be flanged.

• Never crimp fibre glass cord belts. Crimping will cause damage to fibres, resulting in premature belt failure.
