Double Row Angular Contact Ball Bearing 3308 Da Ma Gcr15 for Machine Tool Spindle High Precision

Prevent Spindle Failures with High Precision 3308 Angular Contact Ball Bearing

Machine tool operators know the cost of spindle downtime—missed deadlines, production losses, and expensive repairs. Many face premature bearing failure due to low-quality materials or imprecise manufacturing, especially in high-speed machining applications. Sourcing reliable bearings with the right precision grade and material can mean the difference between consistent performance and unexpected shutdowns.

3308 Double Row Angular Contact Ball Bearing for Machine Tool Spindles

Our Double Row Angular Contact Ball Bearing 3308 Da Ma Gcr15 addresses these challenges with engineering tailored for machine tool spindles. Built to DIN 628-3 and ISO 15:2017 standards, this bearing combines high-quality Gcr15 bearing steel with precision grades up to P5, ensuring stable rotation even under the demands of high-speed cutting operations. Whether you need standard dimensions or custom specifications, our one-stop service covers production, quality control, and global delivery to keep your machinery running.

Optimal Performance in High-Speed Machining Conditions

This bearing excels in machine tool spindles where radial and axial loads act simultaneously, providing rigidity and accuracy critical for precision machining. The double row design increases load capacity, while options for polyamide, sheet steel, or brass cages accommodate different speed requirements—polyamide cages reduce friction at higher speeds, while brass cages offer durability in heavy-duty applications. With open, 2z, or 2hrs seal types, it adapts to both lubricated and contamination-controlled environments, ensuring reliable performance in diverse workshop conditions.

Key Technical Features That Ensure Spindle Accuracy

Precision is non-negotiable for machine tool spindles, and our 3308 Angular Contact Ball Bearing delivers on multiple fronts. The P5 precision grade minimizes runout and vibration, directly translating to better surface finishes on machined parts. Gcr15 bearing steel provides high hardness and wear resistance, extending bearing life under continuous operation. The separated design allows for easy mounting and adjustment, simplifying maintenance and reducing downtime during bearing replacement. Additionally, compliance with international standards ensures compatibility with most spindle designs, eliminating fitment issues.

Por qué comprometerse con la calidad de los rodamientos cuesta más a largo plazo

Choosing low-cost, uncertified bearings may seem economical initially, but the hidden costs add up. Poorly manufactured bearings often fail prematurely, leading to spindle damage, production delays, and expensive repairs. In contrast, our bearings undergo strict incoming material inspection and full-process production supervision, with in-house laboratory testing for dimensional accuracy, noise, and vibration. All products meet ISO industrial standards, backed by our ISO 9001:2015 Quality Management System certification. Investing in quality bearings reduces total cost of ownership by minimizing downtime and extending maintenance intervals.
