Modern machines require both precision and compact design. In industries like robotics, automation, and medical equipment, space is limited but performance cannot be compromised. This is where the RA cross roller bearing becomes a smart solution.
The RA cross roller bearing is designed to provide high accuracy, strong rigidity, and space-saving benefits. Whether you are a new buyer or an experienced engineer, understanding its features can help you choose the right bearing. Yuwei Bearing offers high-quality RA cross roller bearings that meet the needs of advanced industrial applications.
What is an RA Cross Roller Bearing?
An RA cross roller bearing is a compact type of cross roller bearing where the inner and outer rings are separated, making it lighter and easier to install in limited spaces.
Like other cross roller bearings, it uses cylindrical rollers arranged at 90-degree angles. This allows the bearing to support multiple types of loads at the same time.
Key Load Capabilities:
- Radial loads
- Axial loads
- Moment (tilting) loads
Its compact structure makes it ideal for applications where space and weight are critical factors.
How RA Cross Roller Bearings Work
The working principle is based on the cross arrangement of rollers.
- Rollers are placed alternately at right angles
- Spacers keep rollers evenly separated
- Load is distributed across all rollers
This design ensures smooth rotation, high stability, and reduced friction. Even under complex loads, the bearing maintains accurate movement.
