19、286-2) is used for the shaft fitting the spherical plain bearing bore. However, in exceptional cases (for example cylinder installation difficulties), a tolerance of f7 can be admitted. In this instance, a case-hardened shaft is recommended as movement occurs between the shaft and the bearing bore.

20、Lubrication shall then be effected through the shaft. 5.1.2 The specified tilting angle of 4 can still be obtained when the clevis inner faces abut the side faces of the inner ring of the spherical plain bearing. 5.1.3 The rod-end spherical eyes shall be locked with a locking nut. 5.2 Bearing life 5

21、.2.1 The life of the spherical plain bearing is influenced by many factors such as specified load, direction of load, angle of oscillation, type of lubricant and frequency of lubrication. 5.2.2 The spherical plain bearings are designed to give an acceptable bearing life under normal operating condit

22、ions. 5.2.3 Where a constant unidirectional load is applied or other unusual operating conditions exist, consultation with the supplier is recommended. 5.3 Lubrication 5.3.1 Sufficient lubrication shall be provided for the satisfactory performance of the rod-end spherical eyes. 5.3.2 The method and

23、frequency of such lubrication depend on the particular operating conditions. 6 Example of ordering designation A rod-end spherical eye with a bore of CN = 20 mm and steel-on-steel surface shall be designated as follows: Rod eye spherical ISO 8139 20 7 Identification statement (reference to this Inte
