Pipe supports are used to eliminate damage at the pipe crossings caused due to lateral or linear movement of pipes and are ideal for use between pipe & pipe supporting structures or at pipe crossings. They also find usage as structural supports / expansion plates for boilers, pressure vessels, air pre-heaters, electro static precipitators etc. These sliding bearing supports permit unrestricted movement at free end, owing to the changes in temperature or during loading / unloading or due to seismic effect. If the supports are rigid, stress will be developed at the supports & causing major damages to the structure.

Pipe / structural supports are generally designed to meet the requirements of BS 5400 standard section 9.1. Rollon bearings design & manufacture the pipe supports / structural supports with ROLLON SLIDEWAY material as the interface material. ROLLON SLIDEWAY is a composite material consisting of PTFE & sintered bronze along with special wear resistant additives. It is a self-lubricating, wear resistant material suitable for temperatures up to 260 c and not effected by weather & most chemicals.

We can also supply the sliding supports with interface material in virgin PTFE, graphite or any filled PTFE to suit the customers specification.

• ROLLON SLIDEWAY has the lowest coefficient of friction, less than 0.03
• Load bearing capacity of ROLLON SLIDEWAY is higher than any other polymers used for such applications.
• It compensates for surface irregularities & reduces transmission of impact shock.
• Chemicals & weather has no effect on ROLLON SLIDEWAY. Moisture absorption is less than 0.01% even under icing condition or immersion.
• Vibration is damped & allows even distribution of loads.
• ROLLON SLIDEWAY is abrasion resistant & tend to embed foreign particles without any apparent affect on function or life.
• There is no stick-slip action
• The slide bearing can accommodate some misalignment in construction.
• Bearings are simple in construction & can be installed at site.

ROLLON manufacturers Special Spherical Bearings for Nuclear Power Plants. The co-efficient of friction of these Special Spherical Bearings shall be below 0.1 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.

• The solid lubricant used has very low co-efficient of friction, less than 0.1.
• The solid lubricant is suitable for high operating temperature, 600 C.
• Bearing is suitable for maximum load of 34 N/mm.
• 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.
