Back Plates

H HH

epco heavy duty back plates are designed to space the V slides and flat tracks off the mounting surface, providing clearance to accommodate the V bearings, track rollers or bearing blocks. They may be used eitherwithin the customer’s own machine design or in conjunction with the Hepco construction beam. The male key section is designed to locate into the keyway of the slides and flat tracks while the female keyway section(s) are designed to locate either with the customer’s own key section or with Hepco dowel pins (see note 3). The low narrow type back plate (HLN25) and high narrow back plate (HHN25) may be ordered with a jacking screw alignment facility to enable one industrial slide or track to be set exactly parallel to another within a system.

Notes:

1.2.3.4. Overall lengths (‘L’ dimension) are available in 180mm increments up to a maximum of 6026mm . Non-standard lengths are available on request.HLN25 & HHN25 backplates will be supplied with tapped holes and M8 dog point socket set screws to ISO 4028 for customers requiring the jacking screw alignment facility. Hole configuration ‘B’ denotes jacking screw positions corresponding with the fixing hole positions, necessary when used in conjunction with the Hepco construction beam (see fig. 1). Hole configuration ‘A’ denotes jacking screw positions mid way between fixing hole positions and is for general use where customers provide their own centre key section or use Hepco alignmentdowel pins SDPA14 as shown in fig. 2. Pillars are also available with hole configuration ‘B’. Pillars with offset jacking screw holes and fixing hole can be supplied to special order for customers requiring the general alignment facility.Holes for Hepco dowel pins should be reamed tolerance K6 (
+0.002 - 0.007 ) for SDP12 & SDPA14, (
+0.002 - 0.006 ) for SDP8.Approximate weights of the individual components are as follows: HLN25=1kg/m, HHW25=5.3kg/m, HLW25=2.5kg/m, HHN25=3.8kg/m.
