Ball, Spherical Bearings
The tables below provide complete technical information on the type, dimensions, tolerances and installation of radial spherical sliding bearings and CSB ball joint.
In view of the constant evolution of production and technology, this manual is based on current technical data.
Since the application of tiers is influenced by many complex factors, although we have addressed the issues related to their use in these tables, we strongly recommend that users test samples.
Lubricated Radial Ball Joints
Benefits of the lubricated version
Extreme resistance to heavy loads : Metal-on-metal contact offers a much higher radial load capacity than maintenance-free versions.
Extended durability by relubrication : Presence of grooves and lubrication holes allowing regular fat intake to remove impurities and reduce wear.
High impact tolerance Ideal for applications with dynamic load inversions or repeated impacts.

Self-Lubricating Radial Ball Joints
The benefits of self-lubrication technology
Zero maintenance : A drastic reduction in operating costs and production stops related to lubrication.
Absolute cleanliness Ideal for sensitive environments where oil or grease leaks are prohibited.
Minimum friction coefficient : Fluid gliding and reduced wear, ensuring excellent service life even under high static load or slow movements.

Axial Load Ball Joints
The advantages of axial load spherical bearing
Combined burden management : The oblique contact configuration allows effective recovery of the radial and axial forces acting in concert.
Pure axial thrust recovery : The axially loaded versions (button rollers) are specially designed to withstand massive thrust forces parallel to the shaft.
Adjustability and preloading : Possibility to mount these patellas in pairs (in opposition) to cancel the mechanical game and obtain maximum rigidity.
