PRODUCTION PROCESS

The SINTERED IRON OIL RETAINING BUSHING sizes start from an interior diameter of 2mm and can go up to 250 mm, Length up to 80mm.

By P/M technology, The microroughness of the SINTERED IRON OIL RETAINING BUSHING surface enables amounts of lubricant to be transferred. To achieve the perfect surface properties for sliding function, process of impregnation under vacuum conditions by suitable lubricant can guarantee the capacity and the life of the bearing.

LUBRICATION OF SINTERED IRON OIL RETAINING BUSHING

Dry lubrication of SINTERED IRON OIL RETAINING BUSHING with solid lubricants under certain circumstances can achieve better friction coefficients than plastic bushings and casting bearings, for instance. Also SINTERED IRON OIL RETAINING BUSHING with content of graphite could reduce running sounds and good running properties.

An additional lubricant enables the longer service life to be increased.

SINTERED IRON OIL RETAINING BUSHING have a pore volume of between 15% to 30%, and these pores are used by oil impregnation for the bushing's entire service lifetime.

An extremely wide range of operating loads, speeds and temperatures:

u Dynamic loads from 6 to 75 MPa

u Linear speeds up to 8 m/s

u Operating temperatures from - 180°C to + 300°C
