These chain tensioning wheels are ready-to-mount elements, complete with
bearing. They are cost-efficient and can be mounted at the deflection or
tensioning points. Perfect workmanship and stable mounting of the ball
bearing with double front packing cover guarantee a high resistance
against breakage and wear. The extra long internal ring makes the
mounting on machines easy. Also suitable for agricultural and textile
machines. Bearing requires no maintenance, as it is already supplied
with a grease packing. Sprocket burnished. Temperatur range -20º to
120ºC.
