Rod ends requiringmaintenance Maintenance-free rodends

Note SKF rod ends, depending on their design are either completely or par- tially coated with an oily preserva- tive or filled with grease. Skin con- tact should be avoided as these substances may give rise to irrita- tion or allergic reactions. âž” Rod ends with the sliding contact sur-face combinations steel-on-steel and steel-on-bronze require maintenance and must be lubricated. To facilitate this• all SKF steel-on-steel rod ends canbe relubricated via a lubrication hole or grease nipple in the rod end hous- ing as well as via the inner ring ( fig âž” ) with the exception of thesmall-sized rod ends of the E and ESA designs;• all SKF steel-on-bronze rod ends canbe relubricated via a lubrication hole or grease nipple in the rod end hous- ing ( fig ).The recommendations above for steel-on-steel spherical plain bearings manufacturer also apply to steel-on-bronze rod ends.These recommendations also applyto the steel-on-bronze rod ends of the SIKAC .. M and SAKAC .. M series where SKF grease LGMT 3 is recom- mended. It is, however, also possible to use lithium base greases of normal consistency without solid lubricant additives. Rod ends with maintenance-free slid-ing contact surface combinations are generally to be used as dry sliding bearings, i.e. they should not be lubri- cated; the maintenance-free rod ends are without relubrication facilities.However, the service life of steel/-PTFE compositerod ends can be much extended by an initial application of grease followed by occasional relubri- cation. The inner ring is already coated with a lithium base grease before leav- ing the factory.
