SNFA EX45-7CE1-DUM Angular Contact Ball Bearing

The SNFA EX45-7CE1-DUM angular contact ball bearing is a 45x75x16 mm bearing from SNFA, designed for high-precision applications and specified to ABEC 7 tolerance. It is manufactured from chrome steel 100Cr6 and lists a bore of 45 mm, an outer diameter of 75 mm, and a width of 16 mm, with a light preload option described in the model specifications. Key performance figures include a basic dynamic load rating of 13 kN and a basic static load rating of 8.5 kN; the part weighs about 0.24 kg and supports grease-lubricated speeds up to 27,000 rpm and oil-lubricated speeds up to 41,000 rpm. This SNFA bearing is commonly used in high-precision positioning tasks, such as machine tool spindles and precision positioning stages, where controlled preload and load sharing are important.
