For machine tool spindles and other high-precision assemblies, SKF 70 series angular contact bearings with the ACD/P4ADBA suffix handle combined radial and axial loads while maintaining rigidity and accuracy. MR Industrial Accessories supplies this line as part of its SKF bearing offering.
The part number breaks down into four elements. The basic number, such as 7010 or 7020, sets the size and dimension series; the 70 series is a thin-section design with reduced height. ACD denotes a 25° contact angle and a high-strength polyamide cage. P4 is the ISO 4 precision class, with very tight dimensional and running tolerances. ADBA identifies a universal set of two bearings arranged in tandem and matched for direct mounting.
These bearings are common in milling machines, grinding machines and machining centers, where speed and axial rigidity matter. They also appear in drill heads, high-precision motor shafts, metrology equipment and positioning systems. In the metalworking, automotive and capital goods sectors, workshops that build or repair machine tools and plants working to strict tolerances rely on them.
Selection depends on the axial and radial load the bearing will carry and on the maximum rotation speed. Internal clearance and preload are critical, and the two bearings in an ADBA set are matched, so they must not be interchanged with each other. Mounting calls for extreme cleanliness, precise alignment and suitable lubrication, typically high-speed grease or oil. Open or protective-plate sealing is available depending on the environment. Follow the manufacturer's instructions for tightening and shaft arrangement.
Other brands offer similar angular contact bearings under equivalent designations, but there is no universal exact correspondence: contact angle, precision class and matching can differ. Always verify the complete part number and technical specifications before substituting one brand for another. Our team can help you identify the right option.

Frequently asked questions
- What does the ACD/P4ADBA suffix mean on an SKF bearing?
- ACD stands for a 25° contact angle and polyamide cage. P4 is the ISO 4 precision class. ADBA means a universal set of two bearings matched in tandem for direct mounting. Together these suffixes define key performance characteristics.
- Are these bearings matched from the factory?
- Yes, the ADBA suffix indicates two bearings matched in tandem and ready to mount. They should not be separated or interchanged with others, since matching ensures correct preload and alignment for high-precision work.
- How do I choose the right angular contact bearing for my application?
- Consider axial and radial load, rotation speed, required precision and available space. The 70 series is thin-section, which suits tight spaces. Send us your equipment data and part number via WhatsApp or email, and we will help you select the correct option.
