Use these guides when you need to size a coupling, confirm shaft fit, set the hub spacing, replace the flexible element or investigate recurring wear.
NM Coupling Selection Guide
Check torque, speed and bore first, then review the real machine duty.
Installation & Alignment
Set the model-specific S gap and keep radial and angular misalignment within the specified limits.
Elastomerersatz
Identify size, wear pattern and operating conditions before ordering a new flexible element.
Bore & Keyway RFQ Guide
Describe both shafts clearly to avoid machining errors and unnecessary clarification.
Inspection & Maintenance
Check alignment, hub security and flexible-element condition during routine maintenance.
Troubleshooting
Work from symptoms such as repeated element damage, fretting or abnormal vibration.
NM Coupling FAQ
Direct answers to common questions about bore, torque, speed, alignment and replacements.
