Abstract
A slotted tube shaft carrying a blade head of a blade twister rotates in a slotted, stationary bearing housing for an endless band-shaped cutting or sawing element supported by two axially spaced subassemblies each having C-shaped, axially spaced, and slotted inner and outer bearing washers radially between the slotted stationary bearing housing and the slotted tube shaft. The inner and outer washers are fixed in the stationary bearing housing against rotation relative thereto with slots of the stationary bearing housing and washers radially aligned with one another. Respective sets of at least three roller bearings centered on and angularly distributed about the axis and fixed against angular movement between each of the inner washers and the respective outer washer. Each roller bearing radially outwardly engages the slotted stationary bearing housing and radially inwardly engages the tube shaft.
