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.   FEATURES & BENIFITS ROLLON SLIDEWAY has the lowest coefficient of friction, less than 0.03µ 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.   APPLICATIONS PIPE SLIDING SUPPORTS HEAT EXCHANGERS PRESSURE VESSELS HRSG DUCTINGS HP / LP DRUMS ELECTROSTATIC PRECIPITATORS OFF SHORE PLATFORMS REFORMER PLANTS DAMPERS AIR PRE-HEATERS ARCHITECTURAL APPLICATIONS

ROLLON SLIDEWAY is a high performance engineering thermoplastic material consisting of PTFE and sintered bronze along with special wear resistant additives. It is a self-lubricating wear resistant material suitable for operating temperatures upto 260 ° C. It is used on machine tool transfer lines or machine tool guideways or any linear movement applications, to avoid metal to metal sliding contact where reduced friction & wear resistance are critical design considerations.  

ROLLON SLIDE RINGS are used as piston & rod guides due to their outstanding friction behavior, stick slip free running and good resistance to high temperatures & chemicals. Rollon Slide Rings are available in following standard thicknesses, viz 0.8, 1.2, 1.6, 2, 2.5, 3.2 & 4 mm and in varying widths. Example: Thickness X Width X Length"   ADVANTAGES Very good friction characteristics No stick slip effects even at very low speed Prevents migrating of contaminates High wear resistance Damping of mechanical vibrations Long service life High load bearing capacity Protection of the seals Easy Installation Low maintenance TIGHT GEOMETRIC TOLERANCES improve groove fill for better deformation control and load capacity Available in running rolls and cut -to-length strip.

Components like bushes, thrust washers, bearing shells, bushes, rods, etc are manufactured from ROLLON SLIDEWAY material, for rotating, linear or oscillating or a combination of movements. Bushes / rods / components has following features   FEATURES Self lubricity Maintains low co-efficient of friction at high load, low speed operations with excellent wear resistance. Good performance in rotating, oscillating & axial sliding application. Light weight in construction. Operates under wide temperature range -218°c to +260°c. These components (parts) are tailor made to meet the specific requirements of customers and are being widely used in diverse applications like in shock absorbers, wear pads in washing machines, industrial machinery, pumps and many others. Please write to us for your specific applications.

Stainless Steel Linear Slide Rails are simple functional & cost effective solution for linear motion with optimum load capacity and corrosion resistance. Rails are roll formed in Stainless Steel SS304, has no coatings that could flake or ship. Slider body is made of Stainless steel SS304 for high corrosion resistance. Rollers are lubricated for life and sealed against contamination. Rollers have eccentric pivots that allow adjusting the preload when mounted inside the rail. Rollers made with thread integrated inner ring for ease of assembly & preloading.   ADVANTAGES Low Co-efficient of Friction Low Noise Cost Effective Corrosion Resistant Simple & Easy Installations Interchangeability   APPLICATIONS Machine Tool Door enclosures Industrial Washing machines Automation Assembly lines Guide for wood working machinery

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.

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.
