Sanitary Shaft-Mount V-Groove Track Rollers. Support and guide loads on angle rails in food, pharmaceutical, and other sanitary environments. Also known as yoke-style cam followers, these track rollers offer more mounting flexibility than threaded alternatives and are typically mounted on shafts and clevis rod ends.

Very long conveying goods generally do not rest on all conveyor rollers and RollerDrive that are located under them. If, for example, 20 conveyor rollers are under a piece of conveying good, but the conveying good contacts only 15 conveyor rollers, then the load capacity of a roller must be greater than one-fifteenth of the conveying good weight.

roller conveyor''. In a powered roller conveyor, all or a selected number of rollers are driven by one or a number of motors depending on the selected drive arrangement. The driven rollers transmit motion to the loads by friction. The powered roller conveyors may be installed at a slightly inclined position, up to 10° up or up to 17° down.

The optimization of chain velocity and sprocket velocity is very important. There is an optimum speed for a specific chain drive mechanism. At lower speeds, fatigue because of the fluctuating stress at the tight side on-chain is an important effect. At higher speeds, the galling of rollers is a very important factor.
