R1810 Series Deep Groove Ball Bearings

The R1810 is a quintessential example of an inch-series thin-section precision bearing, featuring an inner diameter of 7.938 mm (0.3125 inches). This product is engineered to minimize radial cross-sectional dimensions to the absolute limit—boasting an outer diameter of just 12.7 mm and a thickness of 3.967 mm—while simultaneously ensuring fundamental rotational rigidity. This "large inner diameter, small outer diameter" configuration presents an ideal solution for addressing the rotational support challenges inherent in compact precision equipment.

Bearing Features

Regarding material selection, the product strictly adheres to rigorous bearing steel standards, thereby guaranteeing the material's physical stability under high rotational speeds. It achieves a limiting speed of up to 36,000 rpm under oil lubrication and possesses a basic dynamic load rating of 0.539 kN. This signifies that the bearing is capable of delivering reliable structural support—preventing vibration or run-out during high-speed operation—while simultaneously maintaining high-speed responsiveness.
This specific model finds extensive application across various fields, including computer peripherals, miniature rotary encoders, and precision instrumentation. Through its sophisticated raceway grinding technology and exceptionally low rotational torque, the R1810 strikes an optimal balance between low power consumption and high precision. Its smooth operational characteristics not only serve to mitigate electromagnetic interference within the system but also effectively enhance the accuracy of the equipment's signal acquisition capabilities.
