Single rail applications
Feature 1: Suitable for single rail applications
The HDR model is designed to be used even in tables configured for linear guidance.
Feature 2: Guide rail surface protected from foreign objects
The HDR model ball raceways are located on the sides of the guide rail, making it more difficult for foreign materials to reach the raceways.
Feature 3: Guide carriages and guide rails sold separately
The HDR model has a range of interchangeable guide carriages and guide rails that can be freely combined as long as they have the same model number.
Ideal applications
The HDR model is ideal for applications where a constant MC torque is applied.
Structure of the HDR
The HDR model has raceways on the sides of the guide rail that come into contact with the balls at an angle of 45°. This construction is resistant to tipping in the rolling direction.
DB structure (back-to-back)
This contact structure is designed so that the raceways fully support the balls even when MC moment is applied. This makes this construction very rigid and tip-proof in the rolling direction. It is often used in conjunction with angular contact ball bearings when the moment load is high.
4-way equal load
The HDR model is designed to support the applied loads evenly from all four directions. (Four directions: radial, reverse radial, left and right) This allows this model to be used in any orientation, allowing for a variety of applications.
Radial clearance specifications
The radial play significantly influences the accuracy, load resistance and stiffness. It is therefore necessary to choose a suitable distance. Adequate radial clearance will prevent vibration and shock from occurring when the device is running. Furthermore, it extends the service life and improves the accuracy of the linear guide. The HDR model has three types of radial clearance: normal, light preload and medium preload.
