KA025AR0 Bearing Product Overview & Core Advantages
The KA025AR0 is a thin-section angular contact ball bearing designed for applications requiring precise motion control and space optimization. Featuring a single-row construction with a 30° contact angle, this bearing excels at handling combined loads—simultaneously supporting substantial radial and axial forces. Its Reali-Slim design provides maximum load capacity within an ultra-compact cross-section (0.25" width), making it ideal for weight-sensitive and high-precision assemblies. Manufactured to ABEC-1 precision standards with chrome steel components and brass cage, it delivers reliable performance in demanding industrial environments.
