Rino Industries Ltd has recently launched an impressive range of cylindrical bushings into it's new mechanical drive components catalogue.

The PM-DX cylindrical bushings are made from a composite bearing material developed specially to operate with marginal lubrication and consist of three bonded layers: a steel backing strip and a sintered bronze matrix, impregnated and overlaid with a pigmented acetal copolymer bearing material. The steel backing provides mechanical strength and the bronze interlayer provides a strong mechanical bond for the lining. This construction promotes dimensional stability and improves thermal conductivity, thus reducing the temperature at the bearing surface, the company states.

PM-DX are designed for use with grease lubrication and the bearing surface is normally provided with a pattern of indents. These serve as a reservoir for the grease and are designed to provide the optimum distribution of lubricant over the bearing surface.

There are many characteristics and advantages when ing these bearings, which include the following

o Maintenance free operation
o High pU capability
o Exhibits low wear rate
o Seizure resistant
o Suitable for temperatures from -40 to +120ordm;
o High static and dynamic load capacity
o Good frictional properties
o No water absorption and therefore dimensionally stable
o Compact and light
o Suitable for rotating, oscillating, reciprocating and sliding movements
o They are pre-finished and require no machining after assembly
