51105 bearing is a thrust ball bearing, mainly used to bear axial load. It has the characteristics of good high-speed operation stability, small friction coefficient, strong rigidity and high precision. It consists of four parts: inner ring, outer ring, steel ball and cage. The inner ring matches the journal, and the outer ring matches the bearing seat.
Working principle: When the bearing is stressed, the steel balls roll between the inner and outer rings, and the steel balls are evenly distributed through the cage so that the bearing can withstand large axial loads.
The installation position and function of 51105 bearing in scissor jack
Common applications: 51105 bearings are widely used in various mechanical equipment, such as automobiles, motors, pumps, jacks, etc., to support and position rotating parts. Due to its high precision and high-speed operation stability, 51105 bearings are also often used in precision bearings. In instruments, such as measuring equipment, medical equipment, etc. In scissor jacks, 51105 bearings are mainly used to support and position the rotating parts of the scissor mechanism to ensure the normal operation and stability of the jack.
51105 bearings are usually installed in the support arm or transmission mechanism of the scissor jack. The specific location varies depending on the design.
In the scissor jack, the 51105 bearing mainly plays the role of support and rotation, and can withstand radial and axial loads to ensure the normal operation and lifting function of the jack.
The matching relationship between 51105 bearings and other components
Cooperate with the support arm: The 51105 bearing closely cooperates with the support arm, and realizes the lifting and lowering action of the support arm through the rotation of its inner and outer rings.
Cooperate with the transmission mechanism: 51105 bearings cooperate with the gears, chains and other components in the transmission mechanism to jointly transmit power and torque to ensure the stability and reliability of the jack.
Precautions:
1. Load and speed: When selecting a 51105 bearing, you need to consider its load and speed range to ensure that the bearing can meet actual working needs.
1. Accuracy and clearance: Select the appropriate bearing accuracy and clearance level according to the accuracy requirements of the equipment and the use environment.
2. Installation and maintenance: During installation and use, correct installation methods and maintenance specifications need to be followed to ensure the normal operation and service life of the bearings.
Lubrication and sealing: In order to reduce the friction coefficient and extend the service life, the bearings need to be properly lubricated and sealed.
