How to Order
1 The suffix D1 means the bearing has lubrication holes and
an oil groove. However, for bearing numbers 22330B(K)
and over, the suffix D1 is not needed as the lubrication
holes and oil groove are standard.
2 For bearings with a blank G dimension, no lubrication holes
and oil groove are provided. These features may be added
upon request. (Add suffix D1.)
