World Class Bearing Technology DEVA spherical bearings ®
Open the catalog to page 1Spherical bearings Bearings that allow tilting movements beside rotation and oscillation due to spherical sliding surfaces Maintenance-free spherical bearings are becoming increasingly important in industrial applications. Ever tougher requirements are being placed on machinery and plants when it comes to availability and maintenance. Self-lubricating spherical bearings of the DEVA system offer the best conditions for maintenancefree operation. Spherical bearings with spherical sliding surfaces are ready-to-install machine elements used primarily for oscillating rotating and tilting...

Open the catalog to page 31 Material systems of DEVA® spherical bearings The maintenance-free, high-performance friction materials of the DEVA product range require no external lubrication and ensure a long reliable service life. For the selection of maintenance-free spherical bearings from the DEVA system, the function, use-case, design, and the requirements posed to the overall system are indisputable. Four DEVA material systems are available for the manufacturing of spherical bearings. In principle, each of these material systems can be used for many areas of application. Our application engineers are available...

Open the catalog to page 51.1 deva.glide® Material structure Solid lubricants deva.glide materials consist of high-wear-resistant cast bronze alloys with solid lubricant plugs evenly distributed in the sliding surface in a macro level pattern. The plugs are arranged to optimally supply the sliding surfaces with solid lubricant, adapted to the specific movement. The material’s high density ensures a high load bearing ability which is combined with the good dirt particle embedding ability in the lubricant plugs. In the technical dry run, deva.glide is provided with a running-in film that already permits a transfer of...
Open the catalog to page 6Spherical bearings maintenance-free 1.3 deva.bm® Material structure Solid lubricants deva.bm is excellently suited for low friction or minimum wear rate requirements due to the special properties of the matrix/lubricant system. deva.bm is a self-lubricating, compound friction material composite, consisting of a steel back with a sliding layer of deva.metal applied in a special roll-sinter process. Low friction in deva.bm is provided by the solid lubricant which is homogeneously embedded in the bronze matrix. This is either graphite in various particle shapes and sizes or PTFE. To support...
Open the catalog to page 72 Types of spherical bearings Maintenance-free, self-lubricating DEVA® spherical bearings are available in various basic types: Radial spherical bearings Axial spherical bearings / calotte bearings Special designs 2.1 Radial spherical bearings Radial spherical bearings with spherical sliding surfaces can be moved in all directions and are used for high radial loads. Limited axial loading combined with radial forces are permissible. In this context the ratio between axial and radial load must be observed. Bearing design: fixed bearing – floating bearing In case of multiple shaft bearings,...
Open the catalog to page 8Spherical bearings maintenance-free 2.1.1 Radial fixed bearing in the DEVA material systems Fixed bearings made of deva.glide® Fixed bearings made of deva.metal® The fixed bearing consists of an internally enclosed ball made of stainless steel and an axially divided external ring made of deva.glide, connected by stainless steel retaining rings shrunken onto both sides. The spherical bearing consists of a complete inner ball made of heat-treated steel* and an axially divided external ring made of deva.metal, connected by stainless steel retaining rings shrunken onto both sides. For...
Open the catalog to page 92.1.2 Radial floating bearing in the DEVA material systems Floating bearings made of deva.glide® Floating bearings made of deva.metal® The spherical bearings consist of a complete inner ball made of deva.glide and an axially divided external ring made of stainless steel, connected by stainless steel retaining rings shrunken onto both sides. The lubricating plugs are inserted evenly into the ball bore and along the outer diameter. The spherical bearings consist of a complete inner ball made of heat-treated steel* and an axially divided external ring made of deva.metal, connected by steel...
