Angular Contact Double Row Ball Bearings: Engineering Precision

Angular contact double row ball bearings optimize axial and radial load distribution in high-performance machinery. Unlike single-row variants, these bearings utilize two sets of raceways to handle combined loads up to 30% more efficiently. Industries ranging from aerospace to automotive manufacturing rely on their 40% higher rigidity compared to conventional bearings, with SKF's double row angular contact ball bearing series achieving 98.5% operational reliability in extreme conditions.

Technical Superiority Through Design

The 25° contact angle in double row angular contact ball bearings enables precise load transfer between rows, reducing stress concentration by 18%. Advanced cage designs using glass fiber-reinforced polyamide maintain lubrication integrity at speeds exceeding 12,000 RPM. Manufacturers like SKF implement finite element analysis (FEA) to optimize bearing number configurations, ensuring dynamic load ratings between 85 kN to 220 kN across standard models.

FAQS on angular contact double row ball bearing

Q: What are the key advantages of double row angular contact ball bearings compared to single row designs?

A: Double row angular contact ball bearings provide higher radial and axial load capacity in both directions due to their dual raceway design. They also offer improved rigidity and require less axial space than using two single row bearings.

Q: How do SKF double row angular contact ball bearings handle misalignment?

A: SKF's double row angular contact ball bearings feature optimized internal geometry that accommodates limited angular misalignment. Their high-precision manufacturing ensures smooth operation even under combined loads and minor shaft deflections.

Q: What does the bearing number system indicate for double row angular contact ball bearings?

A: The numbering system identifies bearing type, dimensions, and design features. For example, SKF's 3200 series denotes double row angular contact bearings, where subsequent digits specify bore size and dimensional series according to ISO standards.

Q: When should I choose a double row angular contact ball bearing over other bearing types?

A: These bearings are ideal for applications requiring combined radial and axial loads in both directions, such as gearboxes or pumps. They're particularly suitable where space constraints prevent using multiple single row bearings.

Q: How do I properly lubricate double row angular contact ball bearings?

A: Use high-quality grease or oil matching the operating speed and temperature. SKF recommends their specialized bearing greases applied in quantities filling 30-50% of free space, with relubrication intervals based on operational conditions.
