Product catalog summary
Overview: The RK MonoLine series is designed for high efficiency and flexibility in industrial applications, featuring central lubricating access, variable motor connections, and a secure clamping strip for reliable axis securing.
Key Features and Technical Benefits:
  • Tapered Lubricating Nipple: Facilitates maintenance with central lubricating access.
  • Guided Timing-Belt: Ensures precise movement and positioning.
  • Variable Motor Connection: Compatible with metal bellows and servo couplings for zero backlash.
  • Motor Shaft Configuration: Modifiable post-installation.
  • Clamping Strip: Provides reliable axis securing.
RK MonoLine Z:
  • IP20 protection degree.
  • Flexible motor positioning with pulley boxes.
  • Repeat accuracy of ±0.05 mm.
RK MonoLine MT:
  • Optional motor mounting on each side.
  • Vertical installation with optional locking device.
  • Additional independently movable guide carriages.
RK MonoLine MT Safelock:
  • Secure locking function for gravity-loaded applications.
  • Tested and certified for safety with a nominal holding force of 1500 N.
  • Performance level PL D achievable, with PL E available as a redundant version.
Technical Data:
  • Max speed: 10 m/s.
  • Max acceleration: 20 m/s².
  • Repeat accuracy: ±0.05 mm.
  • Ambient temperature: 0 to +60°C.
Load Characteristics: The load characteristic value (BK) estimates the lifetime of the linear units, with a BK value of 1 corresponding to a lifetime of 12,000 km.
Application Examples: The RK MonoLine MT can be used as both vertical and horizontal axes, with options for additional guide carriages and gearboxes.
Conclusion: The RK MonoLine series offers versatile and efficient solutions for linear motion applications, with customizable features to meet specific industrial needs.
Specifications:
1. Synchronisation Shafts: Lists various RK MonoLine models with specifications such as length per 100 mm travel, total length, and mechanical limit switch details.
2. Mechanical Limit Switch: Maximum voltage is 230 V AC, with a switching current of 4 A and a starting current of 10 A. The operating frequency is up to 5000 cycles per hour, with a mechanical lifetime of 20 million cycles. The degree of protection is IP 67, suitable for temperatures from -30°C to +80°C.
3. External Inductive Limit Switch: Operates at 10-30 VDC with a maximum switching current of 150 mA. It has an operating distance of 2 mm for steel and a degree of protection of IP 67. The ambient temperature range is -25°C to +70°C.
Procedures and Installation:
1. Fixation: External fixation on the guide profile and fixation to the carriage are mentioned for both mechanical and inductive limit switches.
2. Scope of Delivery: Includes limit switches with a set of fixing items and actuators.
Product Range:
1. Linear Technology: Includes manual adjustment units, electric cylinders, lifting columns, and linear axes capable of moving loads up to 3 tons and 12 meters.
