Sapporo Precision Group has been fostering the "EZO Bearings" brand for many years now. EZO Bearings has achieved remarkable growth from a number of domestic and foreign users in 28 different countries throughout the world. In 2003, the Sapporo Precision Group decided to introduce a new brand "SPB" subsequent to "EZO Bearings". "SPB" is the combination of two names, Sapporo Precision Bearings and Shanghai Precision Bearings, which implies the pride of their Super Precision Bearings.
Sapporo Precision Bearings has set-up the most advanced bearing manufacturing plants in Ashibetsu, Hokkaido, Japan and in Shanghai, China. Furthermore, the products produced in Sapporo Precision Bearings' Precision plant in China are from the same exceptional quality Japanese steel and Japanese machinery used in the manufacturing process is the High Precision grade from Japan. This allows both Japanese and Chinese factories to consistently supply highest quality, high-precision ball bearings to the world market.
EZO's manufacture following type:
Extra-miniature bearings are suitable for products requiring high-speed rotation, low-friction torque, low vibration and low noise.
Thin bearings facilitate design downsizing and weight saving. A wide variety of thin bearings is available.
Stainless steel resistant to rust and corrosion is used for manufacturing large-sized stainless steel bearings.
Extra- thin type flanged bearings are used for the downsizing and lightweight designing because of their thin cross section.
The steel balls used in Sapporo Precision Bearings' precision products, conform ball bearing rolling element quality with minimum deviation of sphericity and surface roughness. The sizes range from a diameter of 0.3mm to 114.3mm and are available in either high carbon chromium steel, which offers high wear resistance and load carrying capacity or in stainless steel that offers corrosion and wear resistance.
Standard-class products are manufactured at one class better than standard quality in dimensional accuracy.
This type of bearing with high precision is suitable for products requiring low-torque, low vibration and high-speed rotation.
