[0031] Use principle and advantage: When in use, the bearing inner sleeve 14 can facilitate the point connection relative to the bearing. The rolling body 12 is the key component in the bearing, which is located between the inner sleeve and the outer sleeve, and transmits force and motion through rolling. The retainer 13 is another important component, which is used to uniformly separate the rolling body 12 and guide them to roll on the correct track. The design of the retainer 13 ensures the stability of the relative position between the rolling bodies 12, avoiding direct contact and collision between the rolling bodies 12, thereby reducing friction and wear, and further enabling the bearing inner sleeve 14 to operate normally. Due to the presence of the first clamping block 8, the second clamping block 9 is easily clamped into the circular groove 5, so that the first bearing outer sleeve 1 and the second bearing outer sleeve 2 form an integral whole. When maintenance is needed later, the user can adjust the angle of the second clamping block 9 to the corresponding position of the second clamping groove 4 by turning the first clamping block 8, and then the first clamping block 8 can be directly pulled out of the clamp 3, and the first bearing outer sleeve 1 and the second bearing outer sleeve 2 can be disassembled.

Due to the presence of the clasp spring 6, the second clamping block 9 can be clamped and limited again to avoid displacement, thereby improving the stability of the point clamping of the second clamping block 9 and the stability of the connection between the first bearing outer sleeve 1 and the second bearing outer sleeve 2. Due to the presence of the flow-through hole 15, the user can directly add lubricating oil through the flow-through hole 15 later, so that the lubricating oil can flow accurately into the rolling body 12, thereby effectively reducing the wear of the overall bearing sleeve. Due to the presence of the sealing plug 16, the top end of the flow-through hole 15 can be sealed by the sealing plug 16 after the lubricating oil is added, thereby avoiding the overflow of lubricating oil. Due to the presence of the sealing ring 7, the sealing ring 7 is made of rubber, which has good rubber sealing and rubber elasticity, and can effectively seal the connection point between the first bearing outer sleeve 1 and the second bearing outer sleeve 2, thereby improving the sealing protection of the overall bearing sleeve. Due to the presence of the wear-resistant layer 19, the cast iron material has good wear resistance, corrosion resistance and heat conductivity, and the price is low, which can effectively improve the wear resistance of the first bearing outer sleeve 1 and the second bearing outer sleeve 2. Due to the presence of the heat dissipation layer 18, the aluminum material has good heat conduction and heat dissipation capacity, thereby effectively improving the heat dissipation of the first bearing outer sleeve 1 and the second bearing outer sleeve 2, so as to release the heat generated during operation, thereby improving the stability of the overall bearing sleeve.
