FAQ

Q1: What is a jaw coupling used for?
Jaw couplings transmit torque between two shafts while damping vibration and compensating for minor misalignments.

Q2: Why use PU elastomer inserts instead of rubber?
PU provides higher wear resistance, better chemical and oil resistance, and longer service life compared to traditional rubber inserts.

Q3: Can jaw couplings be customized for my machine?
Yes, bore size, hub material, elastomer hardness, and overall dimensions can be customized.

Q4: How does a jaw coupling reduce vibration?
The PU elastomer insert absorbs torsional shocks and dampens vibrations between connected shafts.

Q5: Which industries use jaw couplings?
Jaw couplings are widely used in industrial automation, material handling, CNC machinery, pumps, compressors, and packaging systems.
