Alternative To Buchse With Lube Grooves

Lubrication grooves fulfill an important task in metallic bushes. Through them, the lubricant gets directly into the bearing point between the buchse and the shaft. The lubricant thus protects the shaft and bushing from dirt and moisture and ensures low coefficients of friction.

The disadvantages Of Buchse With Groove

  1. A buchse with a lubrication groove is quite complex to produce since the groove represents an additional machining step and the inner diameter, depending on the dimensions of the buchse, is difficult to achieve with cutting tools.
  2. The permanent supply of lubricants can only be guaranteed through seamless maintenance.

 

Grease The Groove

Graphite Embedded Bronze Design

Buchse with groove – Either the lubricant has to be replenished by hand using a grease gun or something similar, or it has to be automatically replenished using an expensive central lubrication unit. Last but not least, the lubricants end up in the environment. The lubrication grooves guide the lubricant through the bearing point to the outside.

What could you do without oil grooves? And maybe design the lubrication differently?

Graphite Embedded Bronze Design uses High-grade Metal Alloy as thier base material, embedded Graphite, and grease during the process of friction, it will release solid lubricant and lubricant oil automatically. This bearing is widely used in Injection Moulding Machines, Automobile Moulds, Food Machinery, Water Turbines, Engineering Machinery, etc.

Sinterbuchsen – Oil Impregnation Bushing

Sinterbuchsen approaches the problem of lubricant distribution in a similar but slightly different way than solid bushings with a lubrication groove. The powdered metallurgy process is a mass production process that can reduce costs to a level that can be startlingly low when compared to CNC machining. An added benefit of the sintered metal bushing is the unique pores that are formed in the structure of the metal. These pores can serve as a reservoir for lubricant, providing a passage to the bearing surface. This unique feature adds the benefit of self-lubrication to many powdered metal bearings.

  • The buchse is maintenance-free.

  • sinteredbuchse are robust and pressure-resistant.

  • Oil is only released when the operating temperature is sufficient. If this is not the case, the sinterbuchse metal runs directly and without lubrication on the shaft

Oilless Buchse materials consist of highly wear-resistant copper and brass alloys

Oilless Buchse materials consist of highly wear-resistant copper and brass alloys, whose sliding surfaces are evenly provided with solid lubricant depots in a so-called “macro distribution”.Depending on the movement sequence, the sliding plugs are sufficiently painted over in order to achieve the build-up of a transfer film for a stable operating condition of the plain bearings. The high density of the bronze ensures high resilience with good embedding properties of any dirt particles in the lubricant depots.

Solid lubricant is released from the sliding material due to microabrasion. In this way, smooth surfaces with a firmly adhering film of solid lubricant form on the sliding partners.
