3 3 FEATURES and BENEFITSI nterchangeability of Rail and Ball SlideOne important feature of the Gothic arch is its ability to make high accuracy measurements on both the ballslide and rail, allowing for their interchangeability. This means that replacement ball slides and/or rail can bepurchased individually or as Load Capacity and Long Life NSKhas 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 Resistant DesignAnother design feature of the Gothic arch is its ability toabsorb vertical shock loads from above using four-rowgroove configuration. This design is favorable in case ofunexpected accidents during installation, or theoperation of equipment. The ball groove is designed toavoid edge loading under extreme loads, extending thelife of the Sliders EM and GMNSK has incorporated both through and tapped holes into one flanged slider for a combination of mountingapplications.

4 EM sliders are flanged standard length blocks, and the GM sliders are flanged long to Butt RailsTolerance of ball grooves on the ball slides and rails are controlled to allow for butting, giving you the flexibilityof unlimited lengths. We can offer a stocked Linear guide rail with versatility in assembling preloaded or clearancetype ball Rail Length in one section available up to 4,000 Free K1 Lubrication Units SystemNSK s patented Maintenance Free K1 Lubrication Units are available with our interchangeable Linear Free K1 Lubrication Units are available from stock and provide long-term maintenance freeoperation. For lubrication intense applications, multiple Maintenance Free K1 Lubrication Units can be addedfor extended maintenance free operation. Contact NSK for Performance (HP)Seal for improved dust-proofing and enhanced durability NSK s new triple-lip seal dramatically reduces contaminants from entering the slider and ensures higher greaseretention.
