Operating instructions

Zero-Max L558S is a Schmidt 5D Coupling designed to connect two shafts and transmit torque between them while accommodating misalignment. It is suitable for various industrial applications, including power transmission, motion control, and robotics. The L558S features a compact design, high torsional stiffness, and low backlash. It can handle speeds up to 1000 RPM and misalignments of up to 0.094 inches. The coupling requires lubrication every 200 to 1000 hours, depending on the operating speed. Its key benefits include:

  • Improved shaft alignment and reduced vibration
  • Increased system efficiency and reliability

The Schmidt 5D Coupling will function properly if these
mounting, maintenance, and lubrication instructions are
followed. Failure to observe these instructions may result
in reduced coupling life.
Note: It is important that the following assembly
dimensions and tolerances are maintained before and
during coupling operation.

Position shafts and hubs according to the following values:
A: Hub faces to be parallel within:……………. 0.245 inch
Speeds above 500 rpm should be 0.147 inch or less.
B: Distance between the hub faces:… 4.18+/-.030 inch
C: Maximum shaft misalignment:……………… 0.094 inch
Note: Minimizing misalignment will allow the coupling
bearings to achieve their maximum lifetime. The
Schmidt 5D coupling cannot operate properly at higher
misalignments than listed. For speeds over 500 rpm,
maximum shaft displacement should not exceed 0.056
inch. For speeds over 1000 rpm please consult factory.
D: Mount coupling between hubs.
E: Tighten hub bolts to the end disc of the coupling.
F: Tighten setscrews in hub.
Note: Misalignment values listed are suggested for
at time of installation. This will allow the coupling to
accommodate additional misalignment from operation
over time. Refer to catalog for maximum allowable
misalignment specications.

The Schmidt 5D Coupling should be lubricated after the
rst 200 hours of operation, and again as specied by the
lubrication schedule below.
Note: Always make certain that the lubrication ttings are
clean before adding lubricant to prevent the introduction
of foreign matter into the bearings. Use standard Alemite
ush-type tting Z-737. Recommended lubricant: Darina
No. 2 (EP) oil based grease.
Caution: Rotating equipment is potentially
dangerous and should be properly guarded. It is
the responsibility of the machine builder, user, or
operator to follow all applicable safety codes and
provide a suitable guard. Make sure the machine
is “locked out” and cannot be accidentally started
during installation or maintenance of coupling.
