Cross roller bearing RE series

Cross Roller Bearing RE Series - High-Precision Outer Ring Rotation Solution

When you need exceptional outer ring rotation accuracy for your precision machinery, the Cross roller bearing RE series delivers the performance you demand. This specialized bearing design features an integral outer ring and split inner ring configuration, making it the optimal choice for applications where the outer housing requires superior rotational precision. The product eliminates common issues found in traditional bearings by providing simultaneous radial, axial, and moment load capacity within a single compact unit, reducing your assembly complexity and space requirements.

 

 

Technical Structure and Working Principle

The RE series employs a unique structural design that sets it apart from standard bearing configurations. The solid, integrated outer ring provides exceptional rigidity and rotational stability. The inner ring consists of two separate pieces, allowing for easier installation and maintenance access.

Inside the bearing raceway, cylindrical rollers are positioned orthogonally at 90-degree intervals within precisely machined V-grooves. This crossed arrangement enables the bearing to handle multi-directional loads simultaneously. Roller spacers prevent direct contact between adjacent rollers, reducing friction and extending operational life.

The working principle relies on the orthogonal roller arrangement to distribute loads effectively across multiple contact points. When you apply radial forces, one set of rollers carries the load. Axial forces engage the perpendicular roller set. Moment loads are handled by the combination of both roller sets working together.

Technical Specifications

Performance Advantages

Superior Load Distribution

The crossed roller configuration provides exceptional load-carrying capacity across multiple directions. You benefit from reduced bearing count in your designs since one RE series bearing replaces multiple conventional bearings.

Enhanced Rotational Accuracy

The integral outer ring design delivers superior running precision when your application requires outer ring rotation. This eliminates common accuracy issues associated with split outer ring designs.

Compact Design Benefits

The thin-wall construction minimizes installation space requirements. Your equipment benefits from weight reduction without compromising structural integrity or load capacity.

Low Friction Operation

The orthogonal roller arrangement with precision spacing reduces internal friction. This translates to smoother operation, lower power consumption, and extended service life for your machinery.
