What is a crossed roller way?

A crossed roller way, also known as a crossed roller bearing or crossed roller slide, is a type of linear motion bearing designed to provide high precision and rigidity in linear motion applications. It consists of cylindrical rollers arranged in a crisscross pattern between two sets of V-shaped raceways, typically made of hardened steel.

The rollers in a crossed roller way are oriented at a 90-degree angle to each other and are held in place by cages or separators. This design allows the rollers to bear loads in multiple directions simultaneously, providing high load capacity and rigidity while maintaining precision and smooth motion.

What are crossed roller ways used for?

Crossed roller ways, also known as crossed roller bearings, or crossed roller slides, are used in a variety of applications where precise linear motion, high load capacity, and rigidity are required. Some common uses include:

Machine Tools: Crossed roller ways are frequently employed in machine tool applications such as CNC (Computer Numerical Control) machines, milling machines, lathes, and grinding machines. They provide the necessary precision and rigidity for the accurate movement of cutting tools and workpieces.

Robotics: In robotics, crossed roller ways are used in robot arms and manipulators to achieve precise and smooth linear motion. They enable robots to perform tasks with high accuracy, repeatability, and speed.

Semiconductor Manufacturing Equipment: Crossed roller ways are used in semiconductor manufacturing equipment for wafer handling, precision positioning, and alignment processes. They help ensure the precise movement of components and tools in semiconductor fabrication processes.

Medical Devices: Crossed roller ways are employed in various medical devices and equipment such as imaging systems, diagnostic instruments, and surgical robots. They enable precise motion control in medical procedures and diagnostic applications.

Aerospace and Defence: In aerospace and defence applications, crossed roller ways are used in equipment such as aircraft actuators, satellite mechanisms, and missile guidance systems. They provide the necessary precision and reliability in harsh operating environments.

Precision Measuring Instruments: Crossed roller ways are used in precision measuring instruments such as coordinate measuring machines (CMMs), laser scanners, and optical inspection systems. They enable accurate and repeatable measurement of dimensions and features.

Automated Manufacturing: Crossed roller ways play a crucial role in automated manufacturing processes where precise linear motion is required for handling, assembly, and inspection tasks.

Overall, crossed roller ways are utilised in a wide range of industrial, scientific, and commercial applications where precise linear motion, high load capacity, and rigidity are essential requirements.
