Early (pre 1966) model 34-600 saws with extended Inner Race Bearings required replacement arbor bearings, which are available as a pair.
The bearings have an internal diameter of 17mm (d), an external diameter of 40mm (D), an outer race that is 12mm wide (Bo), and an inner race that is 16.6mm wide (Bi).
SP-5344, 920080405344, and 88503 are all Rockwell/Delta part numbers that are interchangeable.
WJB brand rubber sealed bearings that are dimensionally identical to the original New Departure brand bearings are used in this conversion project.
Model 34-600 saws manufactured prior to 1966 use extended race bearings, whereas model 34-600 saws manufactured after 1966 use non-extended race bearings, Rockwell/Delta part number SP-5335. It is recommended that you determine which bearings your saw makes use of before placing your order.
