Miniature ball rail systems
Linear guides
Bosch Rexroth miniature ball rail guides from the NRII series provide precise linear motion in a compact envelope. The MWA-007 miniature runner blocks are available in narrow (SLS) and normal (SNS) configurations, with preload classes C0 and C1 and in height versions H, N and P. Their small size makes these guides suitable for equipment with restricted installation space where standard guide sizes cannot be fitted.
NRII series MWA-007 - miniature runner blocks in SLS (narrow) and SNS (normal) configurations
Preload classes C0 and C1 - C0 for zero-backlash operation, C1 for increased stiffness
Height versions H, N, P - different height dimensions for varying installation conditions
Compact design - for applications in confined spaces where standard guide sizes do not fit
