OIL-FREE SLIDE UNITS FOR LOOSE CORE

■ 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.

SCY

● Testing method and conditions Tested Product : Oil-free Slide Guide Units for Loose Core Old Standard SCY30 Inclination angle : 15° Reaction : 1471 N{150 kgf} (applied at the ejector plate start up and kept until the stroke reaches 10mm) Stroke : Ejector plate stroke 100mm (Slide plate stroke 26.8mm) Testing speed : 0.42 s −1 {25cpm} (Slide plate's sliding speed 0.04m/s {2.5m/min})

● Results of durability test • Repeated 500,000 times, the test results indicate excellent abrasion resistance with an average wear amount of 0.005mm on the slide base, 0.013mm on the slide plate. • This is considered to be attributable to the slide unit's automatic center adjustment function that helped prevent uneven sliding, and the oil-free bearing's excellent scoring resistance.
