3. Application of KTR Rotex Standard Coupling:
Rotex Standard Flexible Couplings used in most types of machinery, hydraulic pumps, standard engines, and general drive shafts, commonly trusted by factory technicians. The Rotex Standard series is the most renowned and cost-effective type of coupling in the industry.
These devices are capable of transmitting power smoothly, reducing shock vibrations due to the dual arrangement of shock absorbers. Additionally, they absorb shock vibrations generated by unevenly operating machinery, compensating for angular misalignment, and requiring minimal maintenance.

4. Technical of Standard Flexible Jaw Coupling:
The benefits of Rotex elastic couplings include significantly increased resistance to high loads. The shock absorbers deform under high loads and speeds, hence the need for expanded coupling hubs.
All sizes of couplings have a maximum torsional angle of 5º. They can be installed both vertically and horizontally.
