No matter your requirements for moving guided loads, Bosch Rexroth profiled rail systems deliver exceptional accuracy, dynamics and load-bearing capabilities in every industrial and automation environment.
Our rail systems are the result of leading industry knowledge and wide application experience from Bosch Rexroth. They have been optimised according to a consistent focus on improving customer efficiency to give them a competitive production edge:
Innovative engineering, precise manufacturing and high-quality materials deliver wear-free service and constant precision over the entire service life of the guide rail system!
These ball-bearing linear guides are used in machine tools, industrial robots and various special machines. Available in 8 different sizes.View our Ball Rails
High load-bearing and rigid for machine tools, print & paper machinery, injection moulding machines, robots, presses and heavy-duty machinery.View our Roller Rails
Used in applications requiring extremely small ball-bearing linear guides with high load capacity, e.g. medical technology and the semiconductor industry.View our Miniature Ball Rail Systems
These cam roller guides are used in the conveyor and automation sectors, designed for high speeds of up to 10 m/sec.View our Cam Roller Guides
The steel bearing plates of the guide rails are manufactured with such precision that they are subjected to increasing load as the curvature becomes more convex.
This design allows rollers and balls of the runner block to transition smoothly on a tangential, ideally angled deflection curve into the load-bearing zone. This enhances the motion of the guide rails system and produces better machining results and surface quality.
Bosch Rexroth offers unmatched flexibility and efficiency in linear motion systems through its unique design focus on interchangeability.
The rolling element sets and the raceways in the runner blocks and guide rails can easily be replaced by another, regardless of the format, without any problems and above and beyond the accuracy class. This means that each component can be ordered and stocked separately in any accuracy class and format. The advantage to customers? Reduced time and money in terms of logistics, assembly and service.
The cover strip is made of rustproof spring steel, and provides an ideal, smooth surface for linear guide systems. It reduces the chances of the seals wearing out, providing optimum protection against the ingress of chips and fine dust into the runner block when it passes over the bore holes.
The cover strip also simplifies installation, with just a single work step required to cover all bore holes. This eliminates the effort otherwise involved in inserting the conventional plastic caps. With a rail length of 2 m, you can save up to 30 percent of the mounting time.
Cover strips can be delivered either alongside the guide rails or as a separate part for retrofitting, stock-keeping and replacements
With a broad range of materials and design styles, Bosch Rexroth ensures solutions to match the requirements of any linear application.
The following materials are available for runner blocks and guide rails:
Single rail applications are space-efficient and useful in minimising the possibility of other components in the system becoming misaligned. Some single rail applications include:
Linear actuators: Actuators driven by belts, screws or pneumatic cylinders commonly use linear rails because of their excellent ability to withstand moment loads and relatively quick travel speeds.
Overhead transport systems: Linear rails are an excellent choice in guiding loads centred below the rail and bearing block.
Gantry robots: Individual axes on gantry robots typically incorporate a single rail driven by a screw or belt and pulley system.
Higher load requirements often use linear rails in pairs. With the drive mechanism mounted between the dual rails, these systems are compact and sturdy.
Linear stages: Linear rails are the ideal solution in stage systems requiring precise travel accuracy and minimal deflection.
Machine tools: With machine tools, high accuracy and stiffness are critical in facilitating quality workmanship.
Cartesian robots: Cartesian robots need to support and withstand high moment loads, and parallel linear rails are used in guiding most Cartesian robots.
Robot transport units: Dual linear rail systems can be used to provide additional mobility to six-axis robots, guiding them to new locations within a factory or assembly plant.
