Crossed Roller Slide Ways: Precision Linear Motion Solutions by Nippon Bearing

What is a Crossed Roller Slide Way?

A crossed roller slide way is a type of crossed roller guide designed to offer high rigidity, high accuracy, and ultra-low friction, linear motion.

This advanced bearing system consists of cylindrical rollers arranged in a crisscross pattern between two parallel guides.

These rollers are held in place by a metal or resin cage, riding in precision-ground V-shaped grooves.

This innovative design ensures exceptional stability and precision, making crossed roller slide ways ideal for applications requiring exact and reliable linear motion.

Advantages of Crossed Roller Slide Ways

  • Precision Accuracy: The unique crisscross arrangement of rollers provides line contact, resulting in enhanced accuracy and stability.
  • High Rigidity: The multiple contact points of cylindrical rollers ensure high rigidity, making crossed roller slide ways suitable for high-load applications.
  • High Load Ratings: These slide ways can handle significant loads without compromising performance.
  • Ultra-Low Friction Movement: The rollers do not recirculate, ensuring smooth and consistent motion with minimal friction.

Common Applications of Crossed Roller Slide Ways

Crossed roller slide ways are essential in various high-precision and high-load applications, including:

  • Semiconductor Machinery: Ensures precise and stable movement in the production of microchips and other semiconductor components.
  • High-Precision Optical Equipment: Used in devices such as microscopes and laser systems to maintain exact alignment and accuracy.
  • Laboratory Equipment: Provides reliable and precise linear motion in various laboratory instruments.
  • Measurement Instruments: Ensures accurate and repeatable linear movement in high-precision measurement devices.
  • Medical Devices: Essential for imaging equipment, surgical instruments, and diagnostic machines that require precise and smooth motion.
  • Aerospace Engineering: Used in aerospace applications for its high rigidity and precision, ensuring reliable operation under demanding conditions.

Addressing Cage Creep in Crossed Roller Slide Ways

What is Cage Creep?

Cage creep is a phenomenon where the roller bearing cage drifts from its original position over time. This issue can arise in vertical applications, when the full stroke isn’t utilised, or due to vibration and shock loads. Cage creep can significantly affect the performance and lifespan of the crossed roller guide.

Why is Cage Creep a Problem?

When the cage is misaligned and makes its next full stroke, the off-centre cage will bump into an end stop and be forced to centre itself again by skidding. This skidding causes the rollers to slip rather than roll, resulting in metal-on-metal rubbing. This can damage the crossed roller guide, reducing its lifespan and necessitating frequent adjustments and replacements of worn components.

How to Prevent Cage Creep?

Cage creep can be prevented using the NB STUDROLLER system, available for both slide ways and slide tables. This patented system prevents roller guide slippage even in vertical applications, ensuring quieter operation, more accurate alignment, and an extended lifespan.


What is the STUDROLLER System?

The NB STUDROLLER system is an innovative solution to prevent cage creep. It uses rollers with spherical studs that mesh with a row of holes or dimples machined into the raceway tracks. This unique design ensures that the rollers remain aligned and do not slip, regardless of the rail’s orientation.

Performance Benefits:

  • 58% Increase in the Length of Contact Between Roller and Transfer Surfaces: Enhances stability and reduces wear.
  • Quieter Operation and Smoother Movement: Reduces noise and vibration during operation.
  • 53% Increase in Number of Effective Rollers: Results in load ratings 2.3 times higher than conventional sliding bearings.
  • More Accurate Linear Movements and Dynamic Frictional Resistances: Ensures precise and consistent performance.
  • More Stable Motion at Both High and Low Speeds: Improves reliability across a range of operating conditions.
