(Model numbers of types with a driver groove do not include symbol “-A” in the end.) For information on accuracy standards, please refer to A19-14. Those models marked with “＊” do not have a greasing hole and cannot be replenished with grease.

Note2) The rotation speed limit value in the table (*) applies to models that have no seal and use grease lubrication. With those models using oil lubrication, up to 130% of this value is permitted. With those attached with seals, up to 70% of this value is permitted. ● Eccentric type (model CFH) variations Type in which the stud head side and screw side are tapped for pipe fitting (model CFHT) Type with a hexagon socket in the stud head side (model CFHT-A) (suitable for stud diameters of 12 mm or more) Type with a hexagon socket in the stud screw side (model CFHT-B) (suitable for stud diameters of 12 mm or more) Contact THK for information on other variations. Note3) Models CFH24A through CFH30-2A (excluding those made of stainless steel) are equipped with a plug fitted into a through hole connecting the oil hole to the base of the hexagonal socket (see d1 and d2 in the figure on A19-24), to keep grease from leaking out of the socket. When applying grease, make sure the plug is not dislodged from the base of the hexagonal socket by excessive pressure. During greasing, take care to ensure that the plug is not forced out of the hexagon socket by excessive pressure. Oil hole is a blind hole CFH12A to 20-1A CFH12AM to 30-2AM Plug pressed into hexagon socket to render oil hole as a blind hole CFH24A to CFH30-2A A19-25 Cam Follower With cage Mass
