BA9 SKF 9×20×7 Thrust Ball Bearing

Technical Advantages & Industrial Use

Reliable axial support for machinery

The BA9 SKF 9×20×7 is a single-direction thrust ball bearing designed to carry axial loads only, providing stable axial support where radial loads are to be avoided. The bearing ensures consistent axial load handling, making it a solid choice for equipment requiring precise axial alignment.

Compact, durable bearing unit for industrial environments

With inner diameter 9 mm, outer diameter 20 mm, and width 7 mm, this thrust bearing is compact yet robust. Its simple configuration — shaft washer, housing washer, and ball-and-cage assembly — allows for easy mounting and dismounting, facilitating quick maintenance and replacement in industrial settings. Built from high-grade bearing steel, the unit offers durability, resistance to wear, and long service life even under continuous operation.

High performance under axial load and rotation

The BA9 SKF bearing is engineered for demanding industrial applications. It handles axial loads reliably while maintaining smooth rotation at elevated speeds, offering minimal friction and stable performance. Its solid construction and compact size make it ideal wherever reliable axial support is critical for operational efficiency.
