The nuts should be tightened to the recommended torque values listed in (table 1). The recommended tightening torques enable the full load carrying capacity of the cam follower to be exploited. If heavy vibrations occur, the cam followers can be located using self-locking nuts in accordance with ISO 10511 or special lock washers.
For self-locking nuts, a higher tightening torque must be applied. Follow the recommendations of the nut manufacturer.
Most cam followers (all for sizes ≥ 22) have a hexagonal recess in the stud head and can be held in place by a hexagonal key (Allen wrench) while the nut is being tightened. Some cam follower designs of the small sizes 16 and 19 have a slot in the stud head instead, and can be held in place by a screwdriver. For additional information, refer to the illustrations in the product table.
Depending on the mounting conditions, cam followers with an eccentric collar can be adjusted to the required eccentricity via the slot or the hexagonal recess.
Do not hit the head of the stud as damage to the cam follower may result.
SKF recommends positioning the lubrication hole in the stud head in the unloaded zone of the cam follower. The position of this hole corresponds to the marking on the head end of the stud.
The lubrication hole in position 3 (fig. 2) may be used to incorporate a locking device to prevent the stud from turning.
When inserting a plug, it should be pressed into place using a mandrel (fig. 3).
