When encoder shafts meet misaligned drive shafts
In a pump skid retrofit, an engineer found that the encoder shaft and the drive shaft were offset by nearly a millimeter. Direct coupling would have transferred that misalignment into the encoder bearings, risking premature failure. The SICK KUP-0610-J claw coupling solves this by accommodating axial, radial, and angular offsets while transmitting torque reliably. This shaft adaptation coupling features a 6 mm bore on the encoder side and a 10 mm bore on the drive side, making it a direct fit for many SICK encoder models.
Key features and technical specifications of the KUP-0610-J

The polyurethane damping element absorbs shock loads and vibrations, protecting the encoder from harsh conditions. With a maximum speed of 19,000 rpm, the coupling suits high-speed applications. The operating temperature range of –30 °C to +80 °C covers most oil and gas environments, from cold climates to hot process areas.
Why choose This unit for VFD parts and servo motor replacement?
When specifying vfd parts or planning a servo motor replacement, the mechanical connection between motor and feedback device is critical. This unit provides a dependable interface that compensates for alignment errors. Its claw design allows for easy assembly and disassembly without special tools. The aluminum flange offers rigidity, while the polyurethane element damps vibrations that could otherwise distort encoder signals. This makes it a practical choice for retrofit projects where shaft alignment is challenging.
Applications in oil and gas automation
The SICK unit is suited for use with encoders in motor feedback systems, valve actuators, and metering pumps. In a hypothetical scenario, a refinery uses this coupling to connect an encoder to a variable frequency drive (VFD) on a compressor. The coupling's offset compensation reduces wear on the encoder bearings, extending service life. Its temperature range ensures reliable operation in both cold start-up and hot process conditions.
Installation and maintenance guidance
Install the coupling by sliding the 6 mm bore onto the encoder shaft and the 10 mm bore onto the drive shaft. Tighten the socket set screws to a maximum of 150 Ncm. Ensure that axial, radial, and angular offsets remain within the specified limits. Periodically inspect the polyurethane element for signs of wear or cracking. Because the coupling is a wear item, replace it if vibration or backlash increases. Always follow the encoder manufacturer's safety manual for maintenance procedures.
