Abstract:
1. Tension roller or deflection roller for a traction drive, comprising an antifriction bearing ( 3 ), having an inner ring ( 8 ) positioned by a spacer ( 4 a , 4 b ) and a threaded connector ( 5 ), with traction means adapted to be guided on a running wheel ( 2 ) of the tension roller ( 1 ) located on an outer ring ( 10 ) of the antifriction bearing ( 3 ), wherein the antifriction bearing ( 3 ) includes, at least on one side, an axially spaced sealing cap ( 13 a , 13 b ), which overlaps an annular gap ( 14 ) between the inner ring ( 8 ) and the outer ring ( 10 ),wherein the sealing cap ( 13 a , 13 b ) is fixed detachably with at least one of a positive or frictional fit indirectly to the outer ring ( 10 ) of the antifriction bearing ( 3 )and forms a sealing labyrinth ( 23 a , 23 b ) with the spacer ( 4 a , 4 b ), and the sealing caps ( 13 a , 13 b ) are connected to the spacer ( 4 a , 4 b ) so that the spacer ( 4 a , 4 b ) and sealing cap ( 13 a , 13 b ) are joined captively into one structural unit ( 34 ) with the tension roller ( 1 ).
