Rollon Spherical Bearings Rocker Washer Assembly

Product Description

ROLLON manufacturers Special Spherical Bearings for Nuclear Power Plants. The co-efficient of friction of these Special Spherical Bearings shall be below 0.1µ and the working temperature up to 600° C.ROLLON Special Spherical Bearings are used for supporting the Steam Generator Guide supports at Steam nozzle location in Nuclear Power Plants. These special bearings support steam nozzle against loads during normal operating conditions, earthquake and / or pipe rupture events. The Special Spherical Bearings are manufactured with housing in stainless steel and a spherical ball in special alloy bronze fixed with solid lubricant. This arrangement permits free diametrical expansion of steam nozzle, free vertical upward thermal expansion and tilting of Steam Generator and to transfer the loads from Steam generator to supporting structure.
Advantages The solid lubricant used has very low co-efficient of friction, less than 0.1µ. The solid lubricant is suitable for high operating temperature, 600° C.Bearing is suitable for maximum load of 34 N/mm². Chemicals & weather has no effect on the solid lubricant.
The Special Spherical Bearings are manufactured to meet the stringent quality requirement of M/s. Nuclear Power Corporation of India. Bearings have been designed and tested for loads up to 375 MT without any failure or defects.
ROLLON also manufacturers in their state of the art manufacturing facility at Bangalore Sliding Bearing Pads. ROLLON Sliding Bearing Pads are used for Primary Heat Transfer system in a Nuclear Power Plant to eliminate damage at the supporting structure due to thermal expansion. ROLLON Bearing pads permit unrestricted movement due to temperature changes or any other external forces at the free end.
Rocker Washer Assembly.ROLLON manufacturers Rocker Washer Assemblies used as supports for Hanger Rods of Primary Coolant Pumps. The function of the assembly is to allow free movement at very low coefficient of friction of the primary coolant pump along X and Z-axis. The movement is caused by the thermal expansion of the Steam generator – primary coolant pump piping. Rocker Washer assembly shall allow for 6° vertical movement of the hanger road supporting the Primary Coolant Pump under 40 MT load.Advantages:The solid lubricant used has very low co-efficient of friction, less than 0.1µ. The solid lubricant is suitable for high operating temperature, 600° C.    Bearing is suitable for maximum load of 34 N/mm². Chemicals & weather has no effect on the solid lubricant.
