Item specifics
Part Number:693-MF
Bore Dia (d): 3 mm
Outer Dia (D): 8 mm
Width (B): 4 mm
Material: 440C Stainless steel Rings + Si3N4 Ceramic Balls
Quantity: 1 Lot = 1 PC Bearing
Note: ABEC Grades 7, Also, the equivalent ISO classes.
Features:
1, Due to the internal bearing balls is SIC material, so the corrosion resistance ability is very strong, can effectively resist corrosion from seawater.
2, This self-lubricating bearings are oil-free, SIC ball in rotation will produce self lubricating, after cleaning and maintenance do not use bearing maintenance oil.
3, Rotation of the bearing characteristics of high speed, high temperature resistance, often used in special industries, high rotation speed and does not produce corrosion rust in a high temperature environment.
4, Can effectively improve the wheels cast smooth, micro-property and throwing flight distance.
Before purchase, please be sure to take a minute to read the following:
5, SPECIAL NOTE: ceramic ball bearing rotation sound larger than traditional bearings,
Sound like Sha~ Sha~~Sha~~~ , for example in the video.
