Double row deep groove ball bearings

Double Row Deep Groove Ball Bearings

Double row deep groove ball bearings deliver significantly higher radial load capacity than single-row equivalents — all within a compact cross-section. With two rows of balls sharing deep, uninterrupted raceways, they handle combined radial and moderate bidirectional axial loads with excellent running accuracy, low friction, and quiet operation. Ideal when single-row bearings fall short on load but space is limited.

ZMS supply double row deep groove ball bearings in China for 15 years. By using premium material and mature production experience, we supply high quality double row deep groove ball bearings to customers aboard.

Modals: 4200 series, 4300 series

Key Features & Benefits

Enhanced load capacity — Dual rows of balls distribute forces evenly → higher radial loads + moderate axial loads in both directions
Compact design — Same bore & OD as many single-row series (e.g. 62/63), but slightly wider → saves axial space compared to back-to-back single-row arrangements
Low friction & high-speed capability — Deep groove raceways + optimized ball conformity = smooth rotation and reduced heat generation
Excellent rigidity & minimal deflection — Ideal for applications needing stable shaft positioning under load
Quiet & low-vibration running — Precision manufacturing ensures smooth, reliable performance even at elevated speeds
Versatile sealing options — Available open, with shields (Z/ZZ), or contact seals (RS/2RS) for contaminated or high-speed environments
Long service life — High-quality chrome steel + advanced cage designs (steel, polyamide) resist fatigue and wear

Typical Applications

Double row deep groove ball bearings excel wherever single-row versions reach their load limit but you still want the simplicity and speed capability of deep groove geometry:
Electric motors & generators (especially larger frames)
Gearboxes & transmissions
Pumps & compressors
Heavy-duty conveyor systems
Textile machinery
Printing & packaging equipment
Agricultural machinery
Woodworking machines
Material handling equipment
Fans & blowers with combined loads
