Product Description

Core Positioning and Product Attributes

Crossed Roller Bearigns are compact bearigns with their rollers alternatively crossed at right angles to 
each other between inner and outer rings. The rollres make line-contact with raceway surfaces, and, 
therefore, elastic deformation due to bearing loads is very small. 

Specification

 Model Specifications and Key Parameters
High accuracy and load capacity.

Precision ground V-grooved ways and rollers. 
Withstands force in any direction. Alternately crossed rollers 45º angle.
Easy Installation and get used to small spaces. 
Factory preloaded for minimum axial play and low coefficient of friction.

Applicable Scenarios and Application Value

1. Core Application Areas
Precision Machine Tools: Ball screw supports for CNC machine tools and machining centers, suitable for high-speed cutting and precision positioning.
Automation Equipment: Screw drive systems for electronic component packaging equipment and semiconductor wafer handling mechanisms, meeting high dynamic response requirements.
High-end Manufacturing Equipment: New energy battery electrode forming machines, precision laser processing equipment, etc., ensuring operational stability under heavy loads and high speeds.
2. Application Value
Improved Installation Efficiency: The direct bolt-on design eliminates the need for bearing seat machining and end cap assembly, reducing assembly time by over 40%.

Strong performance adaptability: The combination of a high speed of 3100 r/min and a load capacity of 72,000 N covers a wide range of operating conditions, from high-speed light loads to medium-speed heavy loads.
Comprehensive cost optimization: The maintenance-free design reduces downtime, while high-precision features reduce scrap rates caused by machining errors. Simplicity in adjacent structural designs also reduces manufacturing costs. 

After Sales Service

Standard Warranty: 12 months or 2,000 operating hours (whichever comes first).
Extended Warranty: Optional coverage up to 24 months.
Global Support: 24/7 technical assistance .
