KR Series KR40 Concentric Stud Track Roller Crowned Cam Follower

Features of KR Crowned Cam Follower

KR design cam followers, sizes 16 and 19, either without a designation suffix
or with the designation suffix PPA , have one slot in the head of the stud that
enables the stud to be held in place by a screwdriver during mounting. In the
centre of that slot is a relubrication hole to press in a grease fitting or a
plug if relubrication is not required. SUMA also supplies these two sizes with
a hexagon recessed into the head of the stud. They are fitted with sliding
rings made of polyamide 66 and are identified by the designation suffix PPSKA.

Cam followers with the designation suffix PPSKA are not equipped with a
lubrication duct and cannot be relubricated
