K25013AR0 Bearing Product Overview & Core Advantages
The K25013AR0 is a single row angular contact ball bearing from the Reali-Slim mm Metric Bearings series, specifically engineered for applications demanding compact cross-sections and high precision. This bearing is designed to support significant combined loads, efficiently handling both radial and axial loads simultaneously due to its 30° contact angle. Manufactured to ABEC-1 precision tolerances, it ensures reliable performance in high-accuracy systems. Its open design and pre-lubrication facilitate high-speed operation while maintaining a slim profile, making it an ideal solution for space-constrained, high-performance machinery.

K25013AR0 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row angular contact design with a 30° contact angle provides excellent capability for supporting combined radial and axial loads. The use of chrome steel for both rings and balls ensures high strength and durability under demanding conditions.
- Precision & High-Speed Suitability: Manufactured to ABEC-1 tolerance class, this bearing guarantees precise running accuracy. The brass cage provides stability and is suitable for high-speed applications. The open, lubricated design further enhances its high-speed performance.
- Slim Section Design: With a width of only 13 mm and a large 250 mm bore, this Reali-Slim bearing is engineered to save critical space and weight (0.76 kg) in compact machinery designs without sacrificing performance.
- Robust Material Construction: Components made from chrome steel offer high wear resistance and a long operational life. The bearing is pre-lubricated and operates effectively within a temperature range of -30°C to 110°C.
K25013AR0 Bearing Typical Application Areas
The K25013AR0 is ideally suited for a range of high-precision, space-sensitive equipment, including:
- Robotics and automation arms
- Machine Tool rotary tables and indexing heads
- Medical Equipment such as MRI and CT scanners
