Bearings with a spherical outer ring, fitted in housings with a concave bore, can compensate for static misalignment of the shaft, Figure 1:

• if relubrication is carried out, up to ±2,5°
• if relubrication is not carried out, up to ±5°.

The units must not be used to support swivelling or tumbling motion.

The axial load carrying capacity F_a of radial insert ball bearings depends essentially on how they are located on the shaft. The load carrying capacity of the location method is shown in Figure 2.

The precondition for this is that:

• the shaft design complies with the data in Figure 2
• the bearings are located using the specified tightening torque M_A.

For very high axial loads, the forces should be directed through a shoulder on the shaft. If the bearing is subjected to its maximum permissible axial load, please contact us.

The speed limits are dependent on the load, the clearance between the bearing bore and shaft and the friction of the seals in bearings with contact seals.

Figure 3 gives guide values for the permissible speeds. For load ratios C_r/P ＞ 13, the speeds can be increased. For C_r/P ＜ 5, location by means of a fit is recommended, see section Conditions of rotation, link. For both types of applications, please contact us.

Required:

The permissible shaft tolerance is dependent on the speed and load. Tolerances up to h9 are possible.

Conventional drawn shafts will suffice for most applications.
