The Camrol and Cam Follower bearings offered by Mac Marketing are designed and built specifically to withstand intermittent shock and heavy load of cam operation. Full type needle roller bearing construction gives them ultimate in radial capacity, improving load-carrying qualities. A soft stud stem adds toughness and permits reworking for slight dimensional changes. Holes through either side or ends of the stud provide for convenient re-lubrication. Both zone and through -hardening are used to provide the right combination of hardness for maximum life. These bearings are available with or without seals in inch as well as in metric dimensions, in normal and heavy-duty types, including in stainless steel materials for applications in industries like machine tools, aerospace, printing machinery and material handling equipment, etc.
