Description

Spherical roller bearings have rolling elements spherically formed over two rows that roll in a spherical outer ring. The raceways of the inner ring are tilted toward the rolling elements to ensure that the rollers are supported. The hollow spherical shape of the outer ring’s raceway allows the inner ring to swivel outward and compensate for shaft misalignment issues to a certain degree. The bearing clearance of a bearing is identified by means of its C mark (C0, C2, C3 ...). C0/CN: standard bearing clearance class. This mark is usually omitted. C2: decreases bearing clearance C3: higher bearing clearance than C0/CN C4: higher bearing clearance than C3 - in particular for vibration machines and vibrating screen bearings C5: higher bearing clearance than C4, used in particular in high-temperature bearings. Conical spherical roller bearing are fastened to the shaft using an adapter sleeve or withdrawal sleeve. The tightening torque must be observed in such a way that the bearing clearance is not impermissibly restricted. The ease of movement of the bearings is to be checked after installation. There are various possibilities for controlled installation by means of hydraulic nuts in conjunction with the measurement of the displacement path that ensure the secure installation of spherical roller bearings, even with C0/CN bearing clearance. More detailed consulting is possible through our Application Engineering team. The C3 design is recommended for installation with an adapter sleeve because the increased bearing clearance makes a stronger tightening torque possible.
