For the executions with the pre-drilled pass-through hole, in the tables the size “d” of the hole represents the minimum diameter of the hole that can be obtained through machining.
For the -K versions, the keyway machining does not necessarily result in phasing with the gearing.
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.
Maximum tolerance on plain pass-through hole: IT 9.
See: Transmission elements.
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).
