Schmidt 5-D Couplings
(L500 Series)

Most couplings in the Schmidt Coupling line are designed to accommodate either axial, angular, or parallel shaft displacements only.

The 5-D Couplings are a modification of the Schmidt Inline Coupling, designed to accommodate 5 degrees of angular shaft misalignment, as well as axial and parallel misalignment.

• Large shaft misalignment capabilities (angular, axial, and parallel)
• Easy installation for any misaligned shaft position
• No heavy sideloads
• Constant angular velocity.

How to Select a 5-D Coupling

If you wish, you can use the Sizing Software
which will take your information and automatically
suggest the correct Schmidt Coupling.

1- Use this formula to calculate your required HP/100

2- Look in the performance/dimensions chart for a coupling size which has an HP/100 RPM rating equal or greater than your calculated requirement.

No shock Load

1.0
Light Shock Load 1.5
Medium Shock Load 2.0
Heavy Shock Load 2.5
Reversing Shock Load 3.0

3- (Check the Sideloads vs Misalignment chart for more information.)
