The Flexible and Secure Connection Point of Power Transmission
Rubber couplings, which provide the connection between the motor and the driven equipment (pump, gearbox, compressor, etc.) in industrial power transmission systems, act as the "mechanical fuse" of the system. As Sürlas Kauçuk, we manufacture high-performance rubber couplings that ensure high torque transmission while successfully dampening vibrations, shock impacts, and axial/radial misalignments between shafts in the system.
Thanks to our advanced rubber and polyurethane formulations, we protect your mechanical components against wear and breakage even under sudden loads or continuous harsh operating conditions, guaranteeing quieter and more efficient system operation. In addition to standard designs (spider, pin, barrel type, etc.), we offer custom production flexibility in different hardness levels (Shore A) and sizes suitable for the torque requirements and operating environment of your projects.
Key Advantages:
Maximum Shock and Vibration Dampening: Protects the motor and bearings by absorbing mechanical impacts and vibrations generated during sudden starts and stops.
Alignment (Axis) Tolerance: Tolerates angular, radial, and axial misalignments that may occur between shafts during assembly or operation with its flexible structure.
High Torque and Fatigue Resistance: Thanks to high-quality Polyurethane (PU) and reinforced NBR elastomers, it exhibits superior resistance to wear, tearing, and deformation at high speeds.
Mechanical Fuse and Ease of Maintenance: Creates a protective barrier by preventing damage to the main metal components of the system; minimizes downtime and maintenance costs with its easily replaceable structure.
