The FSTH guide roller series has a steel wheel centre with a cast Blickle Extrathane® polyurethane tread. The ball bearing is sealed on both sides, pressed into the wheel centre and secured with a locking ring. Like the FSTH wheel series, the FTH guide rollers provides a high resistance to cut and tear propagation, low rolling resistance and low-noise operation. The FSTH series has a higher load capacity than the FTH wheels because of the steel wheel centre. FSTH series guide rollers are frequently used in luggage and sorting systems and cranes.
