INSTALLATION & MAINTENANCE General installation instructions for a TK coupling: - Align the coupled machines according to the values listed in table 3. - Clean the outside of the coupling. An incorrectly tightened Inaccurate alignment will - Measure the shaft and the coupling bore to check the screw may come loose lead to premature fit. and damage the coupling coupling failure. or other parts of the - Heat the hub to max. 130 ⁰C if required, and cool the drive. shaft with liquid nitrogen. - Depending on the drive, slide the machines against each other while paying attention to the required distance between shaft ends, S in table 2, and install the pins and buffers, or install the pins and buffers first and then move the machines. Altering the coupling by Locking hardware, such - Double check screw tightness and install the coupling machining or welding is as lock nuts, should be strictly prohibited. replaced if removed. cover (Cover sold separately). Servicing a TK coupling: - A TK pin coupling is normally maintenance-free, requiring only visual inspection. - Inspect the rubber buffers for signs of wear, cracks or misformation. A damaged buffer should be replaced with a new one. - To ensure the longevity of the buffers, care should be taken to prevent debris from getting between the buffer and the hub bore .

GENERAL WARRANTY TERMS Warranty terms for TK couplings: – The customer has provided MFG with adequate data of the drive. – Screw tightening torques and alignment Indirect expenses, such precision has been documented during as loss of production, generated from replacing installation. the coupling are not covered. – The coupling has been installed in the drive it was first designated for, and the drive has not been altered after designation. – Only hardware supplied with the coupling have been used. – The coupling has not been damaged during installation by excess heat or by damaging it. – The coupling has been stored appropriately, away from solvents and other chemicals. – The customer has not altered the coupling by machining, welding, etc. – Operating temperature has not exceed the maximum temperature allowed for the type of buffers used.
