AI Technical Summary
Technical Problem
The existing bearings have insufficient sealing, which allows external impurities and moisture to easily enter, damaging the bearings and affecting their service life.
Method used
A bearing with a sealing mechanism was designed, including a protective shell, a sliding member, a left sealing ring, a right sealing ring, and a telescopic seal. By pushing and pulling the sliding member, the telescopic seal extends into the sealing member groove, achieving a tight seal between the left and right sealing rings and blocking external impurities and moisture.
Benefits of technology
It improves the sealing effect of the bearing, prevents external impurities and moisture from entering, extends the service life of the bearing, and reduces the risk of damage.

Abstract
This utility model provides a bearing with a strong sealing effect, relating to the field of bearing technology. It includes: a bearing body, a sealing mechanism disposed on the inner side of the bearing body, the sealing mechanism including a protective shell, a sliding member disposed on the inner side of the protective shell, a sliding groove disposed on the outer side of the sliding member, a left sealing ring disposed on the outer side of the sliding groove, a right sealing ring disposed at the right end of the left sealing ring, and a telescopic sealing member disposed on the inner side of the right sealing ring. This utility model allows the telescopic sealing member to extend and retract by pushing and pulling the sliding member. Through the sealing member slots disposed at both ends of the outer ring, the telescopic sealing member can extend into the sealing member slots, thereby creating a better sealing effect between the left and right sealing rings, preventing external impurities from entering the bearing, reducing damage to the bearing caused by external factors, thus extending the bearing's service life and reducing costs.
