Resistance to impact load

The lower ball groove is Gothic-arched, as are the centers of the upper and lower grooves, with the center of the lower groove offset, as shown in Fig. 2. The vertical load is generally borne by the upper ball rows, where the balls are in contact with the ground.

FAQ


Here are some of the most frequently asked questions about linear guides!

What is a linear guide?

The linear guide is a device consisting of a guide rail and one or more guide shoes, which enables objects or loads to be moved longitudinally (translational movements).

 

It is one of the most important components in machine tools. NSK's linear guides offer numerous advantages, including

  • Extremely precise positioning: up to 2µm for a stroke of 100 mm
  • Translation of the lightest to the heaviest loads
  • Allows slow to high speeds (up to 10 m/s)
  • Can be finger-jointed to increase guide length

 

To identify your prismatic rail, you need to take into account ..:

  • dimensionsthe prismatic rail is standardized under ISO 12090, making it easy to compare different manufacturers
  • Materialwe offer guideways in high-carbon steel and stainless steel.
  • Treatmentswe offer guideways with black oxide surface treatment. Nitriding and anti-corrosion treatments are also available on request.

 

To assist you in your selection, we have provided a configuration tool enabling you to select the various criteria for your linear guide. Our sales department can also assist you with special requests.

How to choose a linear guide?

When selecting a linear guideway, it is important to take several factors into account, including :

 

  • Functional factors related to machine use: it's important to determine the motion configuration, overall dimensions, rigidity, load capacity and positioning accuracy of the linear guide in relation to the machine installed.

 

  • Environmental factors related to your activity: take into account the externalities specific to your activity and the use of the machine in terms of dust, pollution and extreme temperatures.

 

  • Cost factors cost factors: standardized products / calculate the cost of assembly, maintenance and the energy required for operation.

 

 

By taking these factors into account, you'll be able to determine which series of rails to use, as well as the associated pads for a specific load and assembly. Our sales department can provide you with installation recommendations in conjunction with our partner NSK.

Common signs of a defective bearing include abnormal noise (squeaking, rattling), excessive vibration, overheating, lubricant leaks, excessive play or visible signs of wear on the raceways. If you observe such signs, we recommend that you
