SPHERICAL PLAIN BEARINGS
- Requiring maintenance, whose components provide a sliding coupling for the materials steel on steel (or steel on bronze) with lubrication possible through the external and / or internal ring, which is suitable for applications subject to impacts with alternating and small radial loads , bidirectional axial loads.
- In the maintenance-free version, between the outer and inner ring there is a layer of sliding material, which by reducing friction to minimum values , also leads to a decrease in wear, increasing the operating life, thus reducing interventions and costs of lubrication and maintenance ; they are suitable for dynamic loads.
This bearings consist of a threaded terminal which can be male or female with a ball joint, whose characteristics and operation are similar, here too there are two version:
- Requiring maintenance, which are suitable for alternating radial loads, absorbing them traction or compression forces and transmitting them with minimum friction.
- The maintenance-free rod ends work the same way but for slow movements with low angles of oscillation, single-sided loads and for certain versions also for alternating loads; also in this case they require reduced re-lubrication or maintenance.
Solutions developed according to the customer's needs by offering a product that guarantees interchangeability in conformity with the original, guaranteeing the same solutions, satisfying all the original features, possibly without modifications to the adjacent parts and for this reason also very economical.
