ABSTRACT:
A belt tensioner has an elongated support bar formed with a transversely throughgoing aperture and an annular inwardly directed lip around the aperture. A hardened metallic inner bearing race is centered on and elongated along a bearing axis and has one end extending into the aperture and formed with a circumferential radially outwardly open groove in which the lip is snugly fitted. An outer race is mounted on and coaxial with the other end of the inner race and is supported thereon by means of roller-bearing elements. The nonmalleable one end of the inner race does not need to be deformed to secure it in the support bar; instead the support bar, which is normally made of malleable steel, is deformed to make the connection.
