Example

ratio 1:2

SHAFT ‹1› = 10 RPM

SHAFT ‹2› = 5 RPM

----------------------------------

ratio 2:1*

SHAFT ‹1› = 5 RPM

SHAFT ‹2› = 10 RPM

*ratio 2:1: on request; not available in version «D»

The ratio (Fig. 3-4) and configuration is determined by the shaft ‹1› always shown on the opposite side of the fixing bores (✳︎), the others shaft are defined following the clockwise direction

Grease fitting: recommended when the work conditions are not within the parameters listed in Tab. 5 (page 6), to increase the lifetime of the unit, and if its position does not allow easy substitution.

It is necessary, based on the duty cycle, to restore the correct amount of lubricant at variable time intervals (contact our Tech Dept for further information).

The standard position of the grease fitting is shown in Fig. 6 and Fig. 7; it is possible to request a different position by contacting our Tech Dept.
