Abstract
A deflection roller (32) for a deflection roller package (33) of a wire saw (1), having a wheel (32), a pivot bearing (42) and a sealing element (55). The wheel (32) has a raceway (45) along the periphery thereof for guiding a saw wire (3) of the wire saw (1). The pivot bearing (42) is coaxially inserted in the wheel (32). An outer sleeve (51) protrudes from a lateral surface (49) of the wheel (32). An inner sleeve (50) protrudes from a lateral surface opposite the one lateral surface (49). A radius (53) of the inner sleeve (50) is smaller than a radius (52) of the outer sleeve (51). The sealing element (55) is placed on the outer sleeve (51) or inserted into the inner sleeve (50).
