Product description
Characteristic features
Complete guide units can also be designed by combining interchangeable elements from stock
Rexroth manufactures ball guide rails and ball runner blocks especially for the ball raceway sector with such high
precision that each individual component element is fully interchangeable. As a result, any combination is possible
within each accuracy class. This enables globally unique, premium logistics. Each element can be individually planned
and separately stocked.
On ball guide rails, both sides can be used as reference edges.
Highlights
▶ The same high load capacities in all four main directions of loading
▶ Minimal noise level and optimum travel behavior
▶ Excellent dynamic characteristics:
▶ Long-term lubrication is possible over several years
▶ Minimum quantity lubrication system with integrated reservoir for oil lubrication1)
▶ Lube fittings with metal threads on all sides1)
▶ Limitless interchangeability as all ball guide rail versions can be combined at will with all ball runner block versions
▶ Maximum system rigidity due to preloaded O-arrangement
▶ Maximum installation error compensation with super ball runner blocks
▶ 60% less weight with aluminum ball runner blocks (compared to steel ball runner blocks)
Further highlights
▶ Interchangeability with roller rail system
▶Optional integrated, inductive and wear-free measuring system
▶ Wide range of accessories
▶ Attachments on the ball runner block can be mounted from above and below1)
▶ Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center
of the ball runner block1)
▶ End-face fastening thread for all attachments
▶ High rigidity in all directions of loading – permits applications with just one runner block per rail
▶ Integrated all-round sealing
▶ High torque load capacity
▶Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
▶ Quiet, smooth running thanks to optimally designed ball and ball chain return and guideway
▶ Different preload classes
Corrosion protection (optional)
▶ Resist NR: Ball runner block body made of corrosion-resistant steel as per DIN EN 10088
▶ Resist NR II: Ball runner block body and ball guide rail as well as all steel parts made of corrosion-resistant steel in
accordance with DIN EN 10088
▶ Resist CR: Ball runner block body or ball guide rail made of steel with corrosion-resistant coating, matte-silver finish,
hard chrome plated
