Loose old lock rings? Can multi-groove sync positioning + custom lugs solve it?
Traditional locking rings, due to their single-groove design, are prone to displacement in environments with vibration and temperature fluctuations, leading to equipment failures and increased maintenance costs. This paper proposes a three-groove mechanical self-locking structure that distributes impact forces through three balanced points and, in conjunction with custom-designed lugs specific to the equipment, provides dual anti-loosening protection. According to field tests conducted by enterprises, this solution significantly improves equipment operational stability and extends maintenance intervals. We now offer rapid customization to help enterprises permanently resolve locking ring loosening issues and reduce long-term operational and maintenance risks.
