The sleeve fit clearance of sleeve coupling is about 1-2 threads. Jiashan Rongchang sliding bearing has rich experience in producing mold guide sleeves. The general matching is 1 wire, and the precision of Rongchang guide sleeve is within 2 wires. Can also be customized to improve quality.

Based on the strength copper alloy as the basic material, according to the working conditions, holes are machined in a certain proportion on its working face and filled with solid lubricant.

High strength copper alloy provides high bearing capacity, while solid lubricant can form a lower friction pair. Under the condition of dry friction, we design a layer of pre-lubrication film on the bearing surface to ensure that the solid lubricant can be transferred to the dual parts in the shortest time and form an effective solid lubrication film.
