Spherical Roller Bearings Spherical Roller Hearings are parlicularly suitable fur Hpijlicatiuns where misalignment can arise from errar in mounting or from shaft deflection. NACHI Spherical Holler Bearings are manufac- tured in a number of design and material configu- rations depending on the type oí application and See the table below lor the roller, guide ring and cage design for KACI11 Spherical Roller Hearings. They can sustain radial and axial loads. (1) For high axial load ¡ippliradtions. the axial load l'';¡ musi nul exceed o.» oí llie rudial load IT. li llie axial load exceeds il.fì l'r,...

Spherical Roller Bearings Lubrication holes and groove The outer ring of Spherical Roller Bearings arc often made with lubrication holes and a groove for feeding lubricant. The outer ring may also be configured with oil holes only depending on fitting, mounting or service conditions. Heat-stabilized bearings NACHI Spherical Roller iiearmgs are subjected to a beat-stabilization treatment as standard. They can be used al operating temperature of up to 200°C with minimal dimensional changes occur- Lubrication holes and groove

Mounting bearings with tapered bore Mounting bearings wiili a tapered bore requires some experience and technique. Bearings with tapered bore are always mounted with an interference fit on the shaft. To measure Ihe amount of inter lereiice fit on the shaft. Ihe axial displacement of Ihe inner ring or the reduction of radial internal clearance due to the interference fit can be used. Generally, the measurement of reduction ¡ti r;idial internal clear- ance is a more reliable method than measurement of the axial displacement of the inner ring. Maximum permissible misalignment angle is about 2" under...

Spherical Roller Thrust Bearings Aligning angle Maximum permissible misalignment angle, is about 2' under general service conditions. If the aligning advantages of this bearing type are to be realized, care must be taken lo provide clearance for parts Minimum axial load To prevent damage caused by sliding motion between the rollers and raceway, spherical roller thrust bearings must be subjected to a load more ihan the minimum load.
