Rexroth linear modules are precise, ready-to-mount guide systems that combine high-performance characteristics with compact dimensions. Rexroth provides a favorable price/performance ratio and fast delivery times.
Structural design
- Ready-to-install linear modules in any length up to Lmax
- Realization of greater lengths of up to 6000 mm
- Rigid aluminum profile frame with Rexroth ball rail system with cover strip
- Ball runner block with moderate preload (preload class C1)
- Aluminum carriages with T-grooves and centering holes
- Economical maintenance thanks to the central relubrication option (grease lubrication or oil lubrication) from both sides via the carriage
- High-performance toothed belt (AT profile) for high drive torques with simultaneously high rigidity
Attachments
- Planetary gearbox with various gear ratios
- Motor attachment kits according to customer specification
- Servomotor
- Magnetic field sensors for easy assembly
- Switch (proximity or mechanical) cable channel, socket-plug and extension cables in the accessories program
Attachments (range of accessory products)
- Clamping fixtures and sliding blocks
- Connecting shafts
- Connecting technology for linear motion systems
- Sensors and extension cables
