When space is limited and performance can’t be compromised, crossed roller bearings (CRBs) are the go-to solution for high-precision motion systems. At Beining Technology, we design and manufacture CRBs to deliver exceptional stiffness, accuracy, and load capacity—where standard bearings simply can’t keep up.
Why Crossed Roller Bearings?
Unlike conventional ball or roller bearings, crossed roller bearings use cylindrical rollers arranged in alternating 90° orientations, held in place by precision cages and guided in V-grooved raceways. This unique structure unlocks key advantages:
1. High Rigidity & Micron-Level Accuracy
The crossed roller design provides four-point contact per roller, distributing loads evenly and minimizing elastic deformation. This results in superior rigidity—critical for maintaining P4 and P2 precision grades under combined loads. No roller skewing. No loss of alignment. Just consistent, repeatable performance.
2. Compact, Space-Saving Design
CRBs combine radial, axial, and moment load capacity into a single, slim unit. Their ultra-thin cross-section eliminates the need for stacked or paired bearings—freeing up space in tight assemblies like robot joints, rotary tables, and medical imaging systems.
3. Handles Combined Loads with Ease
Most industrial applications involve complex forces—radial, axial, and tilting moments all at once. CRBs are built to handle them simultaneously, reducing system complexity and improving reliability compared to multi-bearing setups.
4. Simplified Assembly & Maintenance
Many of our models feature split inner or outer rings, allowing the full roller-cage assembly to be mounted as a single unit. This speeds up installation, reduces misalignment risk, and simplifies maintenance in field applications.
5. Smooth, Quiet, Long-Lasting
Precision-ground raceways, high-purity SUJ2 bearing steel, and optimized roller guidance ensure smooth rotation, low vibration, and extended service life—even at high speeds.
Where Are Crossed Roller Bearings Used?
Our CRBs are trusted in industries where precision, reliability, and compact design are non-negotiable:
- Industrial Robotics – Articulated arms, wrist joints, and indexing mechanisms
- Machine Tools – CNC rotary tables, indexing heads, and turret systems
- Medical Equipment – CT scanner gantries, surgical robots, and imaging stages
- Semiconductor Manufacturing – Wafer handling, lithography stages, and inspection systems
- Precision Measurement – Coordinate measuring machines (CMMs), optical tables, and metrology instruments
