MIIAM seies ae compactly designed cam ollowes with the stud diamete 2 to and the outside diamete. to 1. They ae suitable o use as ollowe beaings in lightly loaded high pecision cam mechanisms and linea motion mechanisms, and used widely in applications such as electic pats manuactuing and inspection equipment, pecision measuing instuments, and OA equipment. Thust disk type cam ollowes educe wea and heat geneation due to axial loads caused by misalignment, etc. Stainless steel made cam ollowes ae highly esistant to coosion, and best suited o use at places whee oil can not be used, in envionments exposed to wate splashes o in clean ooms.

Tack capacity Tack capacity is deined as the load which can be continuously applied on a am Followe placed on a steel tack suace without causing deomation and indentation (dent) on the tack suace. The tack capacities shown in Table ae applicable when the hadness o the mating tack suace is HR0 (Tensile stength 120/ 2 ). When the hadness o the mating tack suace dies om HR0, the tack capacity is obtained by multiplying the value with a tack capacity acto shown in Table. I lubication between the and the mating tack suace is insuicient, seizue and/o wea may occu depending on the application. Theeoe, it is needed to pay attention to lubication and suace oughness o mating tack especially in case o high speed otation such as cam mechanisms.
