Cross Roller Bearings

Cross Roller Bearings

Cross roller bearings, also known as crossed roller bearings or cross-roller bearings, are precision bearings designed for applications requiring high rigidity, accuracy, and multi-directional load capacity.

Unlike conventional roller bearings, crossed cylindrical rollers are arranged alternately at 90° angles. This structure allows one bearing to support radial loads, axial loads, and moment loads while maintaining a compact design.

LILY Bearing manufactures standard and custom cross roller bearings for precision machinery, robotics, automation equipment, optical instruments, machine tools, and other demanding applications.

Key Advantages of Cross Roller Bearings

High Rigidity

The crossed roller arrangement provides high rigidity and helps reduce deformation under load. This makes cross roller bearings suitable for precision positioning and rotary mechanisms.

Multi-Directional Load Capacity

A single cross roller bearing can accommodate radial, axial, and moment loads. This can simplify the bearing arrangement and reduce the space required for multiple bearings.

High Precision

Crossed roller bearings provide accurate and stable movement, making them suitable for applications where low runout and repeatable positioning are important.

Compact Design

High load capacity and rigidity can be achieved in a relatively small installation space. Cross roller bearing stages, robotic joints, and compact rotary mechanisms can benefit from this design.

Smooth Motion

With the correct preload, lubrication, and installation, cross roller bearings can provide smooth and stable movement with low friction.

Cross Roller Bearing Types

Different applications require different bearing configurations.

Cross Roller Ring Bearing

Designed for precision rotary motion and commonly used in robotic joints, rotary tables, and positioning equipment.

Linear Cross Roller Bearing

Designed for precise linear movement. These bearings are commonly used in precision stages, measuring equipment, optical systems, and automation machinery.

Cross Roller Bearing Stage

Combines a precision motion stage with a crossed roller guide for high rigidity, accuracy, and smooth linear movement.

Face Mount Crossed Roller Bearing

Features a mounting configuration that allows the bearing to be directly attached to mating components, helping simplify installation in compact systems.

Cross Roller Bearings Applications

Cross roller bearings are widely used in:

• Robotics and robotic joints
• Precision rotary tables
• Linear and rotary stages
• Semiconductor equipment
• Machine tools
• Optical instruments
• Measuring equipment
• Industrial automation

Their combination of high rigidity, compact size, precision, and multi-directional load capacity makes them suitable for demanding motion-control applications.

Custom Cross Roller Bearings

Standard bearings may not always meet the requirements of specialized equipment. LILY provides custom cross roller bearings and customized crossed roller bearings based on specific application requirements.

Customization can include:

• Bore and outside diameter
• Bearing width
• Mounting dimensions
• Load capacity
• Preload and clearance
• Accuracy requirements
• Sealing and lubrication
• Special materials or configurations

Customers can provide a bearing model, drawing, dimensions, load, speed, or application information for evaluation.
