Pages 6, 14, 22, 23, 24 and 33 provide identification numbers that you will need to order the components for your application. If you have any uncertainties, or would like more detailed information about any aspect of linear guides, please contact your NSK representative at one of our locations listed on the back cover. FEATURES Interchangeability of Rail and Ball Slide One important manufacturing feature of the Gothic Arch is the ability to make highly accurate measurements on both the ball slide and rail, allowing for tight tolerance control, resulting in interchangeability. This means that additions and/or replacement of ball slides is easily done. High Load Capacity and Long Life NSK has developed an infinite ball recirculating type linear guide with the largest load capacity available (comparing equal size ball slides). This high load capability helps to ensure long life. Compact Low profile Type To minimize space, NSK has developed low profile linear guides to handle various applications. Miniature and Miniature Wide Type Stainless Steel If light loads and corrosive conditions are present for your application needs, NSK can supply a miniature and miniature wide type linear guide in stainless steel. NSK’s built-in ball retainer system allows for easy installation and removal of ball slides. Wide Type If your application requires low profile combined with high load, NSK offers the wide series linear guides. Shock Resistant Design Another design feature of the Gothic arch is its ability to absorb vertical shock loads from above using four-row groove configuration. This design is favourable in case of unexpected accidents during installation, or the operation of equipment. The ball groove is designed to avoid edge loading under extreme loads, extending the life of the unit. DF Arrangement 2 point contact Normal Load Shock Load Normal load is carried on the top two grooves. Shock load is carried by all four grooves. Universal Slider NSK has incorporated both thru and tapped holes into one flanged slider for a combination of mounting applications. (EM/EMZ replaces EL/ELZ and FL/FLZ ? GM/GMZ replaces HL/HLZ and GL/GLZ) Ability to Butt Rails Tolerance of ball grooves on the ball slides and rails are controlled to allow for butting, giving you the flexibility of unlimited lengths. We can offer a stocked linear guide rail with versatility in assembling preloaded or clearance type ball slides. K1 Maintenance Free Lubrication System NSK has the K1 for all five series of interchangeable linear guides. These lubricating units are all available from stock. Maximum Rail Length in one section available up to 4,000 mm. Short Delivery Time We can ship from our large inventory, both standard and custom cut-to-length linear rails. Fluoride Low Temperature Chrome Plating NSK has a plating for linear bearings and rails to cover conditions requiring wet, corrosive and clean room applications. NSK also uses industry approved armaloy coating. These are available from stock. 3 Interchange – Linear Guide (LH & LS Series) Linear Guides are designed for high precision motion and control applications. They provide greater rigidity and higher load capacity than shaft and bushing designs. Some of the industries served - machine tool, robotics, medical and aerospace require smooth travel and high accuracy.
