Replacing Roller Bearings with Self lubricating Plain Bushes

A plain bearing, sometimes known as a sliding bearing, consists of only a bearing surface, with no rolling elements.

These bearings can handle more misalignment than a roller bearings, and are suitable for oscillating or reciprocating movements.

In addition to their simple design and cost effectiveness, plain bushings bearing provide greater load capacity, greater space, lighter weight, and more compact design saves weight. In addition they compensate for deviations, reduce edge loads and suppress noise and vibration. Because they contain no moving parts, bearings also provide a quieter working environment, more reliable performance, and require little maintenance.

These plain bushings advantages are achieved by design engineers in the wide application of plain bushings bearing to replace rolling bearings. These applications include wind turbines, agricultural equipment, steering systems, air conditioning compressors, engine rocker arms, throttles, transmissions and drivetrain, and heads, among others. Potential applications include offshore floating production and storage systems, braking mechanisms, generators and starters.

Plain bearings are not suitable for all applications. Especially where ultra-low friction and/or high precision shaft positions are required. However, plain bearings show excellent performance in the oscillation motion involving high load and slow motion, because the falling off of the rolling parts of rolling bearings may lead to premature failure.

Replacing traditional roller bearings with Viiplus bearings can provide users with technical and competitive advantages. The larger contact area provides high carrying capacity and resistance to fatigue failure, impact and edge loads. The friction characteristics of bearings are also resistant to inertia and high-speed gliding, and the main body of roller bearings tolerate deviations better than many rolling element designs.

Compact overall structure and smaller housing save space and weight. The simple pressing fit almost eliminates the potential damage of installation. Conversion to sliding bearings can also reduce part of the cost of low risk assembly.
