The metric graphite plugged sleeve with dimensions of 50mm inner diameter (ID), 60mm outer diameter (OD), and 50mm length is a specialized component designed for applications requiring precise fitment, wear resistance, and self-lubrication.
Constructed from high-quality materials, this sleeve incorporates graphite plugs that provide natural lubrication, reducing friction and wear between the sleeve and mating surfaces. This self-lubricating feature eliminates the need for external lubricants, simplifying maintenance and reducing operational costs.
The metric size of 50x60x50 ensures precise fitment in equipment components with matching dimensions. The sleeve's length of 50mm provides ample contact area for secure positioning and stable performance.
Applications for this type of graphite plugged sleeve range from heavy machinery to precision equipment where reliable and long-lasting wear protection is essential. Whether used in mining, manufacturing, or other industries, this sleeve offers a robust and dependable solution for ensuring smooth and efficient operation.

Economical bearing: insert type solid lubrication bearing
Inlaid bearings not only save oil and energy but also have a longer working life than ordinary sliding bearings. Metal base inlaid solid self-lubricating bearing (JDB for short) is a kind of novel self-lubricating bearing that has the characteristics of both metal bearing and self-lubricating bearing. The metal substrates bear most of the load during the friction process. Through friction, the solid lubricant in the oilless bearing bushing in the hole or groove transfers or reversely transfers to the friction surface, forming a solid transfer film with good lubrication, firm adhesion, and uniform coverage on the friction surface, which greatly reduces friction and wears.As the friction of self-lubricating steel sleeve is carried out, the embedded solid lubricant is constantly provided on the friction surface to ensure good lubrication of the friction pair during long-term operation. It breaks through the boundaries of ordinary bearings depending on oil film lubrication. It has the advantages of high bearing capacity, impact resistance, high-temperature resistance, small friction coefficient, low abrasion, no noise, strong self-lubrication performance, etc. It is especially suitable for heavy load, low speed, reciprocating or oscillating, etc.

Performance

Graphite Plugged Cast Bronze Bushings can be utilized where heavy loads must be supported at low to medium speeds

The Plug Graphite Cast Bronze Bushing is able to withstand high temperatures up to 570 F
The self-lubricating feature allows bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds.
Self-lubrication with specially embedded solid lubricants reduces friction. Coefficient of Friction: 0.04 to 0.2
