To ensure the high precision and long-term stable operation of THK BNFN7020-5 ball screws, regular maintenance is essential. First, apply the appropriate grease periodically based on the working environment and usage frequency to prevent dry friction and wear. Second, check for unusual noise or increased backlash between the screw and nut, and address any issues promptly. In addition, clean the screw shaft regularly to remove dust, chips, and other contaminants that may enter the raceway and affect transmission accuracy. When the equipment is idle for long periods, use anti-rust measures such as applying protective film. With proper maintenance, THK BNFN7020-5 ball screws can achieve longer service life, higher operational efficiency, and reduced equipment downtime and costs.
