NSK LA Series Linear Guides (machine tools)

NSK LA Series Linear Guides (machine tools)

NSK LA Series high-rigidity ball guides use a six-row ball arrangement for machine tool applications. Sizes 25 to 65.

Key features

  • Six rows of balls for very high load capacity and rigidity
  • Designed for machine tools and heavy-duty equipment
  • Flanged and square ball slides, high-load and super-high-load types
  • Double seal, protector and bellows available
  • No ball retainer: balls fall out when the slide is withdrawn
