Inclined pin Inclined pin guide bush
■ Features of Oil–free Slide Units for Loose Core • Enables the inclined pin to slide smoothly when pushing out a loose core (including undercut) at an angle. • The inclined pin holder slides within the range of θ , and the automatic center adjustment function reduces wear and scoring on the guide and slide plates.

■ Mounting examples
• Refer to the above table for dimensions of the inclined pin's edge cutout and screw size (PM). The counterbore in the inclined pin holder is made in a size that accommodates a socket head cap screw with a spring washer. • The unit can be mounted on an ejector plate in two ways: (1) Screwing into the ejector plate, or (2) Screwing into the unit. For (2), use a socket head cap screw that corresponds to BM in the "Bolt Hole Dimensions" table. For (1), select a rank below the corresponding BM (i.e., M6 screw when BM is M8). • Prior to mounting, apply ＊ grease to the unit in order to protect it from wear during initial running–in. • If the stroke is long, it is recommended that you use a bushing that supports the inclined pin.
