MATERIAL
Glass-fibre reinforced polyamide-based (PA) technopolymer, grey colour.

STANDARD EXECUTIONS
- ZCL-0.5: module 0.5, not drilled hub (number of teeth Z ≤ 50) or plain
pass-through hole (number of teeth Z ≥ 55).
- ZCL-1.0: module 1.0, not drilled hub (number of teeth Z = 10) or plain
pass-through hole.
- ZCL-1.5: module 1.5, plain pass-through hole.
- ZCL-2.0: module 2.0, plain pass-through hole.
- ZCL-2.5: module 2.5, plain pass-through hole.
- ZCL-3.0: module 3.0, plain pass-through hole.
In the execution with the plain pass-through hole, the size d in the tables
represents the diameter of the minimum hole that can be obtained
through machining.

FEATURES
The torques indicated in the tables are granted with rpm included
between 0 and 150. Torque values can vary depending on lubrication,
temperature, pairing with different materials and continuous operating
hours.

TECHNICAL DATA
See: Transmission elements.

SPECIAL EXECUTIONS ON REQUEST
- Assembly by means of a transversal grub screw.
- Hub with hole and keyway in compliance with DIN 6885/1 tolerance P9.
- Maximum tolerance on plain pass-through hole: IT 9.

MOUNTING
To pair two spur gears, a positive backlash must be considered. For
modules 0.5 - 1.0 - 1.5 is recommended the tolerance (+0.03 +0.1).
For modules 2.0 - 2.5 - 3.0 is recommended the tolerance (+0.08 +0.3).
