OIL–FREE SLIDE UNITS FOR LOOSE CORE –STANDARD / ADJUSTING TYPE–

■ 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.

• 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.

4. Make sure to fix the inclined pin by tightening it up using the socket head cap screws or socket low head cap screws.

5. Be sure to prevent loosening by welding the lock nut and the adjusting rod together in the final process.
