NACHI - 71904-E-UM | Angular Contact Ball Bearings - Spindle | 20 × 37 × 9 mm

Details

NACHI 71904-E-UM is an angular contact ball bearings - spindle with inner diameter 20 mm, outer diameter 37 mm and width 9 mm. Additional specifications include bore type CYLINDRICAL, cage YES and lubrication STANDARD.

These bearing is a high-speed, super-precision angular contact ball bearing, typically associated with high-speed spindle applications. Part of the 719 series (ISO 19 series), characterized by an ultra-thin section for applications with limited space and high speed requirements. These bearings have a smaller cross-section for a given bore size, making them ideal for compact assemblies where space is limited but high speed is required. Material : Constructed from high-carbon chrome steel (SUJ2) for maximum fatigue resistance. Features are : Low vibration and low heat generation, High stiffness due to preload, High rotational accuracy, Smooth operation, Easy installation, Improved raceway curvature, Wide Operating Temperature Range. Applications : Robotics & Automation, Medical & Healthcare Equipment, Aerospace and Defense, Pumps & Compressors, Semiconductor Manufacturing, Textile Machinery, Renewable Energy. E=25° Contact Angle, U=Universal Matching, M=Medium Preload.
