Castfil is a self-lubricating compound possessing high mechanical strength. It bonds to most metals / plastics and offers long life protection against wear, abrasion & corrosion. Applications : Repair of scored guideways. Filling of bolt holes in machine tool guideways. Repair of blowholes, porosities, discontinuities, etc in castings, Repair of damages caused by abrasion or corrosion. Rebuilding of critical machined parts. Repair of oversized bearing housing, worn out shafts, etc. Prevention of leakage in gas or liquid pipelines or valves.

Protective enclosures and doors for machine tools. The linear motion solution : > COMPACT RAIL IS HARDENED STEEL linear bearing rails with hardened steel precision rollers and is easy and cost effective to mount to all, even non-machined, surfaces; > COMPACT RAIL SELF-ALIGNS TO ANOTHER RAIL if mounting surfaces are not perfectly parallel (T+U and K+U rail systems); > COMPACT RAIL WORKS IN ANY ENVIRONMENT. The sliders run inside the hardened steel rails where they are protected. They have spring-loaded wipers which protect the shielded or sealed bearings from debris and damage; COMPACT RAIL IS A FAST (up to 9 m/s) AND SILENT SYSTEM (much faster and much more silent than any recirculating ball system); > COMPACT RAIL HAS LUBED FOR LIFE bearings with patented wiper technology that lubricates the system as it runs.

EXAMPLES AND APPLICATION FIELDS:

ROLLON TB 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 2600 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.

> Heavy Duty Drawer Slides > TELESCOPIC RAIL ARE MADE FROM COLD-DRAWN BEARING STEEL - not from bent sheet metal. > TELESCOPIC RAIL HAVE HARDENED RACES to provide the smoothest movement and the longest lifetimes. > TELESCOPIC RAIL WORK WELL WITH SHOCKS AND VIBRATIONS that render other slides inoperative immediately. > TELESCOPIC RAIL HAVE MINIMAL DEFLECTION at the tip of the fully extended slide - even while carrying maximum loads. This deflection is often less than 1 mm. > TELESCOPIC RAIL CAN REACH STROKES OF OVER 2 m (6.5 ft) in one direction and can double that by doing the same out the other side. EXAMPLES AND APPLICATION FIELDS: > Protective enclosures and doors for machine tools >Battery chest, sliding doors (railways) >Movable platforms (automotive) >Medical instruments >Telescopic handlers

UNILINE is a family of linear actuators designed to facilitate the work of the design engineers. It is manufactured using only top quality components. > UNILINE IS A COMPLETE SOLUTION. Based on the linear rail from the ROLLON COMPACT RAIL family mounted in an extruded aluminum-alloy profile, it is compatible with the myriad of standard mounting accessories available in the market; > UNILINE IS VERSATILE. With many configurations and sizes available, including versions with extra long and/or multiple trolleys; > UNILINE IS SMART. Allowing the designer engineers to spend time elsewhere instead of in the details of the linear motion; > UNILINE IS SAFE. With the linear rail and slide placed inside the aluminium alloy profile, the units easily comply with modern safety norms protecting workers from moving parts; > UNILINE MAKES ECONOMIC SENSE. The highest quality components are skilfully assembled and are ready to mount and go;

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 TB SLIDEWAY material as the interface material. ROLLON TB 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.

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 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 0.1. > 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.

Rollon bearings have tied up with M/S. FORSHEDA, SWEDEN for the manufacture of EPDM pipe seals in series 575 in India. the F-575 is a rubber seal for plastic pressure pipes and waste water conduit in ground. The F-575 seal is a combined lip & compression seal. the seal is positioned in the socket by the pipe manufacturer. the seal design gives low assembly forces making pipe joining easier. the F-575 seal meets the European standards for both pressure & vacuum, deflection & shear loads.
