Description

Basic Parameters

In bearing 61902，

“6”: Indicates the bearing type is a deep groove ball bearing, the most common rolling bearing with a simple structure and easy installation. It primarily bears radial loads and can withstand limited axial loads.
“19”: Represents the diameter series code. The “19” series denotes an extra-extra-light series, meaning the bearing has an ultra-small cross-sectional size relative to its inner diameter, optimized for space-saving designs.
“02”: Inner diameter = 02 × 5 = 15mm.
Tolerance grade: Not explicitly indicated in the model, but typically assumed to be grade 0 (normal precision), suitable for general-purpose applications.
The bearing model 61902 signifies a deep groove ball bearing, extra-extra-light series, 15mm inner diameter, and normal precision level. Its ultra-compact design makes it ideal for high-speed applications with space constraints, such as miniature electric motors, precision instruments, laptop cooling fans, and small robotic components, where it can handle radial loads and limited axial forces efficiently.

Product Application

The Deep Groove Ball Bearing: 61902 is widely used in miniature electric motors, precision instruments (e.g., optical scanners), laptop cooling fans, medical micro-pumps, dental equipment, small robotic joints, wearable device motors, wireless earbud rotors, miniature gearboxes, camera focusing mechanisms, watch movements, aerospace miniature actuators, and micro-textile machinery, among other fields.
