Mounting and Lubrication Instructions for Schmidt Inline Couplings

For Coupling Models: L463C & L485C

The Schmidt Inline Coupling will function properly if these mounting, maintenance and lubrication instructions are

followed. Failure to observe these instructions may result in reduced coupling life.

Mounting Instructions

It is important that the following assembly

dimensions and tolerances are maintained

before and

during coupling operation.

Lubrication Instructions

The Schmidt Inline Coupling should be

lubricated after the first 200 hours of

operation, and again as specified by the

lubrication schedule below.

RPM Under 500 to Over

500 1000 1000

Lube Every Every Every

Cycle 1000 500 200

Hours Hours Hours

Note: Always make certain that the lubrication fittings

are clean before adding lubricant to prevent the

introduction of foreign matter into the bearings. Use

standard Alemite flush-type fitting Z-737.

Recommended Lubricant:

Darina No. 2 (EP) Oil based

grease

Position shafts and hubs according to the following values:

1. Hub faces to be parallel within:--------------------------------------------------------Æ

Speeds above 1000 rpm should be .015 inch or less.

Minimizing angular misalignment will allow the coupling bearings to achieve their maximum lifetime.

2. Distance between the hub faces:-----------------------------------------------------Æ

3. Maximum shaft misalignment not to exceed:--------------------------------------Æ

The Schmidt Inline Coupling cannot operate properly at higher misalignments than listed. For speeds over 1000 rpm,

maximum shaft displacement should not exceed 0.060”.

4. Mount coupling between hubs. After installation of the coupling, check that the center disc is free to move laterally a small

amount (approximately .015”-.025”). Remove handling bolt

after coupling has been fixed to the hubs.

5. Tighten hub bolts to the end discs of the coupling.

6. Tighten setscrews in hub. If shock loads are expected, use two set screws per hub.
