Why does the bellows cover begin to experience sticking or unstable movement after more than six months of use?

In most cases, this is caused by the long-term accumulation of metal chips, dust, or other foreign particles generated during machining. Regular cleaning of the following areas is recommended:

• Bellows cover surface
• Guide and limit rails
• Sliding areas
• Surrounding chip accumulation areas

If cleaning and maintenance are neglected for an extended period, sliding resistance may increase and component wear may accelerate, resulting in sticking, unstable operation, and potentially reduced product service life.
