Self-lubricating sintered plain bearings made of bronze and iron
Self-lubricating sintered plain bearings are among the most tried-and-tested products in our range and have been used millions of times over in the most diverse applications. Bearings must have the longest possible lifetime, even at the high speeds of rotation and temperatures normally employed nowadays. Lubrication is the magic word for the longest possible bearing lifetime. The purpose of the process is to fill the open pores of the sintered body with the chosen lubricant. In sintered plain bearings, impregnation is a prerequisite for hydrodynamic operation. (Self-lubrication).
The choice of lubricant depends on various criteria, such as:
- application and use of the end product.
- service life and environmental conditions.
- compatibility with the parts in the immediate surroundings.
- type of installation and position of the sintered plain bearing.
Thanks to their precision and purity, our bearings are characterised by smooth running and offer optimum hydrodynamic conditions.
Besides the standard bearing forms and standard tolerances, you will find over 1,000 different dimensions and versions in our range. Naturally materials, form and lubricant can be adapted to suit the specific requirements of the operating environment. We deliver cylindrical bearings, collar bearings or cup and ball bearings and also other forms on enquiry. The tolerances can also be changed for special requirements.
Our sintered bronze bearings are extremely resistant to corrosion and exhibit outstanding running characteristics. Sintered iron bearings represent an ideal inexpensive alternative. Running noises are reduced and the lubrication of the contact surfaces is improved by means of the addition of graphite to the sinter material.
