KF140BROK Bearing Product Overview & Core Advantages
The KF140BROK is a high-performance thin section angular contact ball bearing designed for applications requiring exceptional precision and load capacity. Featuring a single row design with a 30° contact angle, this bearing excels at handling combined radial and axial loads simultaneously. Manufactured to ABEC-1 precision standards with inch dimensions, it offers a compact cross-section (0.75" width) while maintaining impressive load ratings (7,043 lbf dynamic, 19,790 lbf static). The open construction allows for custom lubrication schemes, making it ideal for precision machinery where space constraints and high reliability are critical.
