Selective Fit Pins and Bushings Precision Guiding …

1 Selective Fit Pins and BushingsPrecision Guiding for DiesInnovation, Quality, and a Full Line, both Inch and MetricProtected by and International PatentsTHEINNOVATOR OFOURINDUSTRY 2 Guide Pins and Bushings -We offer the full range, inch & metric Our Plain Bearing line offers you three types of guide pins(straight, demountable and double diameter) and two kinds ofbushings (demountable steel and our unique, patented SinteredBronze Bushing.) All of these components are color-coded forSelective FitTMand are fully interchangeable with one another. Our Ball Bearing line employs the same three guide pins plustwo styles of ball Bushings (straight sleeve and demountable).Unlike our competitors, our design is interchangeable with allmajor ball bearing brands on the market. Finally, you have atyour disposal a one size fits all ball bearing line. We manufacture and stock the world s largest inventory ofDanly style metric Guiding . Why? Because in North Americawe are READY Technology, outside North America we areDanly International*, and we manufacture and sell Danly diesets and Guiding through our ten plants and offices in Europeand in the Far East.

2 Now we re making our extensive line ofmetric components available to our customers.*Make no mistake:Neither Ready Technology or Danly International or any of theDanly companies outside North America is affiliated in any way with Danly Die Set orConnell Limited PartnershipOverviewIndex3667781212131314 161819In the followingpages, you will see a number of innovative ideasdesigned to increase the performance of your stamping tools,reduce your inventory costs, simplify die assembly and mainte-nance, and maximize available die space. Here are some of the highlights:READY Plain andBall Bearing Components Each Ready pin serves a dual function - it can operate as aplain bearing pin or a ball bearing guide pillar. This saves youthe cost of a dual inventory. Ready s Selective FitTMsystem matches each pin to the correctbushing to achieve the proper fit. Each part is color-coded(white, blue, or yellow), so as long as the color spot on the pinmatches that of the bushing, the running clearance in eachpin/bushing pair in your tool will be the clearance grows in proportion with the pin diameter, Selective FitTMautomatically gives you the proper running fit foryour application.

3 You now have a choice of clamping methods with our demount-able pins. You can secure the flange with traditional toe clampsand screws, or you can hold the pin in place with a stopwasher mounted in the underside of the die shoe. By eliminat-ing the toe clamps you gain extra die space. Another innovation which saves space is Ready s patentedRing System. In effect you can now use our ball bearing sleevebushing like a demountable bushing. Since the sleeve bushingand Ring System clamps have a smaller footprint than a tradi-tional demountable bushing you save on die space.

Like our Precision press fitpins, they are case hardened to 60 - 64 Rc, then core temperedfor can be assembled to the same die set plate hundreds oftimes without distorting the hole center distances or damagingthe holes themselves.

4 So they not only simplify die building andmaintenance, but they ensure maximum accuracy as demountable pins can be held in place either with toeclamps and screws, or with a retainer plug. This second optionincreases the die space Steel Bushings (-645)Our Steel Bushings are manufactured to the same high level of Precision as ourSintered Bronze Bushings .

5 A layer of bronze is sintered to the inside diameter of asteel bushing, creating a mechanical bond at the bronze/steel interface strongerthan that of traditional plated Bushings . Please refer to the following page for double diameter pins are also designed for use with ball bearing as well asplain bearing Bushings . They are case hardened to 60-64 Rc for wear resis-tance, then core tempered for toughness. A tapped hole is provided at the endof the pin for the ball cage press fit diameter is interchangeable with familiar brands of plain bearingand ball bearing pins, so Ready double diameter pins may be used for diemaintenance as well as for new types of pins, 2 types of bushings4 Bronze plating is not a simpleprocess. If the bushing is dirty orthere are contaminants in the platingsolution, the bronze will not adhereproperly and will peel away from thesurface. The fourth batch of bush-ings, for example, will be less likelyto be defect-free than the first batchplaced in a tank with fresh second problem with plating isthat the thickness of the bronze layerdepends on the plating time.

6 A thickbronze layer is simply too costly toproduce, and on large diameterbushings in particular, problems arisewhen the thin plating wears awayand the underlying steel comes incontact with the guide s Sintered Bronze Bushingssolve both problems. Using a patent-ed manufacturing process, a layer ofbronze is sintered to the inside diam-eter of the steel bushing, creating astrong, reliable mechanical thickness of the bronze layer isnot limited by time or cost con-straints, so it is thicker than platedbronze, and it increases proportion-ally with the bushing can test the bond strengthsyourself. Cut through the diameter ofa plated bushing and you stand agood chance to see peeling. Do thesame with our sintered bushing andyou will see that the bronze-steelbond is unaffected. If you need toshorten the inserted diameter to fitour bushing into a thin stripper plate,you can do so without harming is a third advantage to oursintered Bushings . Because sinteredbronze is porous, it holds the lubrica-tion oil in place and helps tomaintain an unbroken lubricationlayer, which improves wear resis-tance.

7 The bronze pores act assmall oil reservoirs, so our SinteredBronze Bushings are more forgivingif maintenance has been , for best results, we recom-mend regular, periodic lubricationwith a high viscosity oil. 5 Compare theBronze ThicknessThisview reveals the greater bronzethickness and the porosity of ourSintered Bronze magnified views of bushingcross A Closer Look ..Compare The Thickness ..This view reveals the fusion bondingof the thick sintered bronze layer to thesteel substrateSintered BronzeThickness- up to 22 timesthicker than platedbronzeplated bronze thicknesssintered bronzesintered bronzeNote porosity:this traps andretains oil forlonger substrate100x magnification1000x magnificationfusedbond Thicker Bronze: The sintered bronze in our Bushings issubstantially thicker than the plating technology it replaces.
