K17020AR0 Bearing Product Overview & Core Advantages
The K17020AR0 is a high-performance Angular Contact Ball Bearing designed for applications requiring exceptional precision and reliability. Engineered as a Single Row bearing with a 30° contact angle, it is optimized to handle significant combined loads, including high radial loads and unidirectional axial loads simultaneously. Its ABEC-1 tolerance class ensures consistent, high-precision operation, making it ideal for demanding industrial environments. The bearing features an open design for versatile lubrication options and is constructed from durable Chrome Steel for extended service life.

K17020AR0 Bearing Structural Features & Performance Benefits
The K17020AR0's performance stems from its precision engineering and material selection. The 30° contact angle is key to its excellent axial load capacity (Static: 12,810 lbf), enabling it to handle substantial thrust loads in one direction. The single row design with a brass cage provides stability and is suitable for high-speed applications. Its Chrome Steel construction ensures high hardness and wear resistance, contributing to a dynamic load rating of 5,454 lbf and a static load rating of 11,345 lbf. The thin-section design (20mm width) saves space and weight (1.32 kg) without compromising strength, while the ABEC-1 precision and minimal radial internal clearance guarantee smooth, accurate rotation with minimal runout.
