Features and Benefits
Crossed Roller Design
Crossed roller bearings deliver an exceptional combination of high precision, rigidity, and load capacity within a single, compact unit. Their unique design features cylindrical rollers arranged in an X-pattern between V-shaped raceways. This allows them to simultaneously handle combined axial, radial, and moment loads, effectively replacing multiple bearing setups. As a result, they simplify mechanical design, save space, reduce weight, and provide smooth, quiet operation with high rotational accuracy. These advantages make them the preferred solution for demanding applications such as industrial robots, precision machine tool rotary tables, medical imaging equipment, and automated manufacturing systems.Superior Rigidity
The single-row raceway structure with crossed rollers provides exceptional stiffness compared to conventional multi-row bearings. This can lead to better positioning accuracy in your equipment.
Compact Footprint
Achieve higher load capacity in less space. The efficient roller arrangement means you can downsize your bearing housing without sacrificing performance.
Low Running Noise
Precision-ground raceways and optimized roller spacing minimize vibration and acoustic emissions. This makes Crossed Roller Slewing Bearing ideal for laboratory instruments and medical devices.
High Rotational Accuracy
With radial and axial runout controlled to tight tolerances, these bearings maintain precise positioning even under varying loads. Your machine maintains accuracy over extended operating periods.
Split Outer Ring Construction
The divided outer ring simplifies installation in confined spaces. Retaining rings secure the assembly while allowing straightforward maintenance access.
Applications
Precision Machine Tools
Rotary tables, indexing heads, and milling machine swivels benefit from the high rigidity and accuracy these bearings provide.
Industrial Robotics
Joint actuators and rotary platforms require compact, high-precision bearings that handle complex load combinations. Our crossed roller designs meet these demands.
Medical Imaging Equipment
CT scanners and X-ray positioning systems depend on smooth, quiet rotation with minimal runout. The low noise and high accuracy make these bearings suitable for clinical environments.
Measuring Instruments
Coordinate measuring machines and optical inspection systems require repeatable positioning. The stiffness and precision of crossed roller bearings ensure measurement reliability.
Automation Systems
Pick-and-place machines, rotary indexers, and assembly equipment use these bearings where space constraints meet high-performance requirements.
Testing & Certification
All products undergo comprehensive inspection before shipment:
· Dimensional verification using coordinate measuring machines
· Vibration and noise testing under loaded conditions
· Material composition analysis and hardness testing
· ISO 9001:2015 quality management certification
· RoHS compliance for hazardous substance restrictions
We maintain complete traceability records for each production batch, ensuring you receive bearings that meet specified performance criteria.
Installation Guide
Pre-Installation Checks
Verify that mounting surfaces are clean, flat, and free from burrs. Confirm dimensional tolerances of mating components match bearing specifications.
Mounting Procedure
1. Position the bearing on the mounting surface, aligning the bolt holes carefully
2. Install clamping rings or mounting bolts finger-tight
3. Check that the bearing seats evenly with no gaps
4. Tighten fasteners in a star pattern to specified the torque values
5. Verify smooth rotation before applying full loads
Lubrication
Apply prescribed grease to raceways if not pre-lubricated. Take after your equipment manufacturer's grease plan for ideal benefit life.
Alignment
Ensure associated components keep up appropriate arrangement to avoid edge loading and untimely wear.

FAQ
Q: What's the difference between crossed roller and conventional slewing bearings?
A: Crossed roller designs use a single raceway with X-arranged rollers, providing higher rigidity and precision in less space compared to multi-row standard bearings.
Q: Can you provide custom sizes?
A: Yes. We offer non-standard customization based on your specifications or by replicating existing parts.
Q: What accuracy grade should I choose?
A: P0 is suitable for general applications. P6 and P5 meet higher precision requirements. P4 is recommended for high-precision spindles requiring minimal runout.
Q: How do I determine the right bearing size?
A: Our engineering team can assist with load calculations and selection based on your application parameters. Please Contact Us with your requirements.
Q: What is your typical lead time?
A: Standard sizes are shipped from stock. Custom bearings typically require 4–6 weeks, depending on complexity.
