Sintered bushings vs. polymer bushings

Sintered bushings

Sintered bushings consist of a sintered bronze body - hence, the name. The main feature of sintered bronze bushings is their porous design, which contains lubricant. Should the viscosity decrease due to increasing operating temperatures due to friction, the oil leaks out. At higher speed, a lubrication wedge develops, which lowers the bushing's friction.

The homogeneous, consistent structure with solid lubricants and reinforcing materials operates without requiring lubrication. This ensures that the solid lubricants incorporated in the material are always available irrespective of the type of movement. Excellent coefficients of friction and wear are given over the entire product life cycle.

In order to ensure smooth and uninterrupted production process, the calibration basket of the machine must be cleaned at regular intervals. In most cases, modern high-pressure cleaners are used. In solutions with conventional bearings, this procedure washes the lubricant out of the plain bearings or even flushes particles of dirt in. This causes problems in the form of downtime which results in additional costs. To solve this problem, iglidur® plain bearings, which are self-lubricating, are now used.
