FAQ

What is the significance of the 'EJW33' suffix in the model number 22226EJW33?

The 'EJ' designation indicates that the bearing is fitted with a two-piece, window-type stamped steel cage. The 'W33' suffix signifies that the bearing's outer ring has an annular lubrication groove and three lubrication holes, facilitating efficient grease or oil distribution.

Can this 22226EJW33 bearing be used with oil lubrication, and what is its limiting speed?

Yes, this bearing is suitable for both grease and oil lubrication. The W33 lubrication groove is ideal for circulating oil systems. The limiting speed depends on the lubrication method and operating conditions, but for this model, the reference speed is typically around 2,400 RPM with oil lubrication. Always consult the manufacturer's datasheet for precise limits based on your application's load and temperature.

What is the recommended mounting procedure for a bearing of this size?

For a bearing with a 130mm bore like the 22226EJW33, it is typically mounted with an interference fit on the shaft. The recommended method is using a bearing heater (induction heater) to expand the inner ring for easy and damage-free installation. Alternatively, hydraulic mounting methods can be used. Never use a hammer or direct force on the cage or rolling elements.
