Timing belt tensioner roller CAFFARO 1697

Description:

Generator belt tensioner roller 1697 CAFFARO is a bearing that has a plastic pad on its outer ring. The belt moves along the surface of this pad. There is a landing sleeve inside the roller. There are two types of rollers: Eccentric - the construction of which is quite simple. It has only a bearing, a plastic cover and a sleeve. Through the sleeve there is a hole offset from the center of the roller. Through the hole, the roller is put on a pin, which is installed on the engine. For tension, the roller must be turned relative to the bolt. A roller with a bracket is a construction that is permanently fixed on a bracket. With the help of bolts, the structure is attached to the power plant. Moving the bracket relative to the engine adjusts the tension. Manufacturers sometimes use rollers with a spring bracket. The spring allows you to independently adjust the tension. Additional information: The bearing is the main weak point of the roller. This part is forced to constantly feel the load. The wear of the part sometimes even ends with its complete breakdown.
