FAQ

'DDU' indicates that the bearing is equipped with contact rubber seals on both sides, providing excellent protection against dust and moisture. 'CM' refers to a special internal clearance for electric motors, which ensures low noise and vibration. 'AS2S' specifies the type of grease used, in this case, Kyodo Yushi Alvania S2.

While DDU contact seals offer superior protection, they also generate more friction than non-contact seals, which can limit the maximum speed. This bearing is optimized for moderate speeds typical of electric motors. For very high-speed applications, a bearing with non-contact (VV) seals might be more appropriate.

For a bearing with a 110mm bore, proper mounting is crucial. It is recommended to use a bearing heater to evenly heat the bearing to around 80-90 deg C above the shaft temperature before mounting. This allows it to slide onto the shaft without applying force to the rolling elements, preventing damage.
