SEALED CHAINS

LGB’s Rolon Sealed chains are used in motor cycles where the rear drive system is open to atmosphere and not enclosed by chain guard. These drive chains need special attention to avoid mud and dirt not to enter into the bearing area. For this kind of application , special chains called the seal ring type chains are designed, in which the bearing area is protected by the seal rings by not allowing the mud and dirt to allow into the bearing area and also not allowing the grease available in the bearing area to come out its working zone.
