CHOOSING PLAIN SPHERICAL BEARINGS
A plain bearing weighs half that of a similar-sized, needle or roller bearing.
Roller or needle bearings can be hundreds of times more expensive than a plain bearing. This is due to their complex design and multi-component system. Added to the increased tooling cost, plain bearings are the cost-effective alternative.
Plain bearings have a larger surface area than rolling-element bearings. Engineers can use space-saving smaller plain bearings that can accommodate similar and sometimes even heavier loads than roller or needle bearings.
LESS PARTS TO BUY
A reduced amount of parts and a simpler overall design means fewer components to break, need repair and low maintenance requirements.
Plain bearings have a higher load-spreading capability over roller or needle bearings, better withstand shock loads and can tolerate misalignment.
Plain bearings, even when slightly misaligned, do not concentrate loads on balls or rollers, but distribute them consistently and evenly. They accommodate small changes in pressure well compared to more complicated bearings.
