Bearing for a tube shaft of a bandsaw-blade twister

A bearing assembly for a slotted tube shaft carrying a blade head of a blade twister for rotation about an axis of a slotted stationary bearing housing for an endless band-shaped cutting or sawing element, the bearing assembly comprising at least two axially spaced subassemblies each in turn comprising:

• a C-shaped and slotted outer bearing washer radially between the slotted stationary bearing housing and the slotted tube shaft;
• a C-shaped and slotted inner bearing washer axially spaced from the outer bearing washer and radially between the slotted stationary bearing housing and the slotted tube shaft;
• an anchor retaining the inner and outer washers in the slotted stationary bearing housing against rotation relative thereto with slots of the slotted stationary bearing housing and rings washers radially aligned with one another;
• and
• a set of at least three roller bearings centered on and angularly distributed about the axis and fixed against angular movement between the inner washers and the outer washer, each roller bearing engaging radially outwardly engaging on the slotted stationary bearing housing and radially inwardly engaging on the slotted tube shaft.
