DKLFA30100-2RS DKLFA30100 30x62x38 Precision Angular Contact Ball Bearing for Screw Drives

Product Description

Core Positioning and Product Attributes

The DKLFA2080 bearing is a representative example of a triple row angular contact ball bearing. It belongs to the category of precision bearings and is designed specifically for screw drive systems, serving as a core support component for highly dynamic operating conditions. Its inseparable unit structure comprises a geometrically stable, thick-walled outer ring, balls, a cage assembly, and an inner ring. Precision-matched components achieve preset performance, making it widely used in industrial applications requiring stringent precision, rigidity, and reliability. 

The bearings are available with and without fixing holes in the outer ring. Bearings with holes are screw mounted directly on the adjacent construction. This solution is particularly economical since there is then no need for the locating bore that would otherwise be required or for the bearing cover with the associated matching work.

Key Structural and Performance Features 

1. Core Structural Design
Dual-row Layout and Contact Angle: The double-row ball design with a fixed contact angle of 60° ensures both axial and radial load capacity, making it particularly adept at withstanding high axial loads. It also offers excellent overturning stiffness (for example, the ZKLN100160-2Z boasts a tilting stiffness of 5800 Nm/mrad).

Mounting Method: Unlike the ZKLF series, which features mounting holes, the ZKLN series must be installed in the bearing housing bore. The outer ring is axially secured via the bearing end cap. When clamped with a precision locknut, the ferrule precisely achieves the set preload and eliminates play.

Sealing and Lubrication System: Two sealing options are available: the suffix "2RS" is a lip-type contact seal, providing excellent dust and water resistance; the suffix "2Z" is a gap seal, suitable for higher speed requirements. The bearings are pre-loaded with GA28-compliant lithium soap-based grease, ensuring lifetime maintenance-free operation under most operating conditions. A lubrication connector is provided on the outer ring for easy relubrication.

2. Performance Advantages
High Precision and High Rigidity: Advanced processes optimize the raceway surface quality, keeping axial runout to within 3μm (e.g., model ZKLN100160-2Z). Axial stiffness reaches 1900 N/μm, ensuring machine processing accuracy. Improved Load Capacity and Life: Using specially heat-treated ring materials for enhanced resistance to solid particle wear. For example, the ZKLN100160-2Z offers a dynamic load capacity of 140,000N and a static load capacity of 435,000N.

Low Friction and High Speed compatibility: Optimized raceway design reduces frictional losses and minimizes temperature rise. With grease lubrication, the maximum speed reaches 2,150 rpm, a 60% increase in speed compared to conventional bearings.

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.
