Carint^® Sinter bronze plain bearings

We recommend Carint^® sintered slide bearings for minor and specific bearing load and slide velocity up to a maximum of 2 m/s.

Technical Data

Alloy: Copper-tin (CuSn)
Density: > 5.8 kg/dm³
Expansion coefficient: 19·10 -6 1/K
Pore volume: 20 - 30%
Standard oil impregnation: Mineral oil, approx. 55 cP at 50 °C

Fields of application

• Mechanical engineering including special machine building
• Construction of jigs and fixtures
• Automotive industry

Admissible loads and application fields

The admissible load of a plain bearing bush depends on:

• the circumferential speed of the shaft
• other operating conditions such as: adequate heat dissipation / additional lubrication

The above diagram gives a survey on the usual loading capacity as a function of the running speed under the pre-condition of normal heat dissipation. The admissible bearing pressure p results from the quotient of bearing force F and the projected bearing running surface = length b by bore diameter d of the bearing bush.

The shown load capacity curve can not be extrapolated to higher or lower speeds. In the case of very low speeds the formation of the oil film is defective and the working conditions are less favourable. For higher speeds heat dissipation and additional lubrication are required.

A particular examination is necessary:

• for bearings with oscillating movement
• for bearings with self-rotating bush
• if heat dissipation is hindered

(For loads above the curve shown in the diagram we recommend solid Carobronze^® Plain Bearing Bushes or CAROPLUS^® Plain Bearings).
