Jai Bharat Castings are front runner in Bearing Chocks for the steel re-rolling mills, roller flour mills and other various milling industries, bearing chock is the one of the most important part of modern rolling mills and they have the main influence on the tools of every rolling mill, bearing chocks are installed in between window of rolling mill stands these chocks directly keep the rolls in place, The middle axis of every chock is the base of the overall geometry, all relevant surfaces have to be adjusted to this axis, bearing chocks are ideal for anti friction roller bearings.

Indefinite chilled rolls are basically controlled under actual casting and molding conditions, does not solidify completely, even surface contains small amounts of very finely divided carbide, the graphite gradually increases simultaneously in size and in amount from surface to core accompanied by decrease in carbide content, the matrix is generally pearlitic throughout the cross section, indefinite chilled rolls are using extent of silicon, chromium, nickel and molybdenum, resulting, that the working face is no longer completely white (this feature make it different from clear chill rolls where the chilled-zone is graphite-free clear and white) the desired hardness is obtained by changing the carbide/graphite balance which is achieved by a close control of chemistry and process parameters     Advantage: This variety is generally cheaper than the spheroidal graphite cast iron rolls, the gradual change in hardness associated with the indefinite-chilled structure allows deeper grooving i.e. indefinite chilled rolls are superior in biting performance, indefinite rolls produce excellent results while achieving maximum functional depth, ensure minimum sacrifice of clear chill layer, as the presence of graphite in indefinite chilled rolls offers strong resistance to thermal shock occurring at the time of accident in the rolling operation compared to other types of cast roll Roll of this type have hardness up to about 70 Shore °C can be grooved for use in roughing and finishing stands, for processing sections such as T-bars and U-sections, and for roughing and intermediate rolls of wire and rod mills.   Indefinite Chilled Cast Iron Roll Applications: :: ICCI Rolls for TMT Rolling Mills           :: ICCI Rolls for U-Section Mills   :: ICCI Rolls for Narrow Strip Mills         :: ICCI Rolls for Thin Flat Rolling Mills :: ICCI Rolls for T-Section Mills              :: ICCI Intermediate Stand Rolls :: ICCI Rolls for Wire Rod Rolling Mills    :: ICCI Finishing Stand Rolls   :: ICCI Rolls for Round Rolling Mills        :: ICCI Roll for Deep Section Mills Manufacturing Range of Indefinite Chilled Cast Iron Roll: Roll Diameter Upto 24 inches or 610 mm Barrel Length                         Upto 52 inches or 1220 mm Overall roll length up to 120” or weight 5mt under the scope of manufacturing Material Specifications Process Hardness Clear Carbon Chilled Cast Iron Static Casting                55-65 Shore°C Ni-Cr Alloyed Chilled Cast Iron Static Casting                60-70 Shore°C Low Carbon Cast Iron                    Static Casting                45-55 Shore°C

Jai Bharat Castings has maintained its leadership in designing & manufacturing of chilled cast iron straightening rolls (reels / rings) solution for almost all straightening applications through its clear chill compound casting, profile of the working surface is decisive for the production process of straightening applications high surface profile have sufficient hardening depth due to its advanced centrifugal casting , beside manufacturing chilled cast iron reels JBC also able to produced  high chromium, nodular iron, adamite, spheroidal graphite iron or forged / tempered, straightening rolls / reels for special applications , straightening rolls / reels are available semi-finished , full machined or axel mounted condition   Advantage: Maximum & desired chilled depth is achievable due to our advanced centrifugal casting machines double layer centrifugal casting gives uniform layer of white iron for working hardness along-with high wear resistance, crack resistance & spalling resistance  Applications: :: Straightening Rolls for Structure Mills         :: Straightening Rolls for T-Section :: Straightening Rolls for Bar Straitening        :: Joist & Beam Straightening Rolls :: Straightening Rolls for Angel Straitening    :: Pipe & Tube Straightening Rolls :: Rolls for Strip Edge Preparation                 :: Rolls for Forming Applications Manufacturing Range: Barrel Diameter 6” to 24” inches or 150 mm to 610 mm Barrel Length 6” to 48” inches or 150 mm to 1220 mm Under the scope of supply   Material Specifications Process Hardness Adamite Steel Static Castings                              45 – 55 Shore°C Ni-Cr Alloyed Chilled Cast Iron      Centrifugal Cosmpound Cast  60 – 70 Shore°C EN Series Forged / Tempered   40 – 55 Shore°C Indefinite Chilled Cast Iron Centrifugal/ Static Casting    50 – 60 Shore°C S.G.

Pearlitic Spheroidal Graphite Rolls have a thick layer of cast iron with nodular graphite, the name of such roll is based on the fact that the material consists of nodular graphite and carbides in a pearlitic matrix, the softest grades have a pearlitic matrix containing ferrite around the graphite nodules, while the higher hardness grades have a complete pearlitic matrix, the carbide content increases proportionately with the hardness.   Acicular Spheroidal Graphite Rolls: Acicular Spheroidal Graphite Rolls also have a thick layer of cast iron with nodular graphite, here, the name of such roll is based on the fact that the material consists of nodular graphite and carbides in a pearlitic - bainitic matrix, the carbide content is considerably higher in the harder grades than the softer ones.   Advantage: S.G Iron Rolls are so superior in wear resistance to that of cast steel rolls that they are specially adapted for roughing and intermediate plate mills and rod or bar mill roughers. as a result of the spheroidal form of the graphite, s g iron rolls are much stronger than rolls of the clear-chill type and the gradual fall in hardness is an added advantage, as such, these rolls are particularly suitable for skelp and strip mills, also bar billet mills, and are being increasingly used for other applications.   Applications: :: SG Iron Rolls for TMT Rolling Mills :: SG Iron Rolls for Automatic Rolling Mills   :: SG Iron Rolls for Narrow Strip Mill          :: SG Iron Rolls for High Speed Mills :: SG Iron Rolls for Plate Rolling Mills        :: SG Iron Rolls for Roughing Stands :: SG Iron Rolls for Wire Rod Rolling Mills :: SG Iron Rolls for Tube Rolling Mills   :: T - Bars & U -Section Mill Rolls                :: SG Iron Rolls for Deep Section Mills Scope of Supply: Barrel Diameter Up to 24 inches or 610 mm Barrel Length Up to 48 inches or 1220 mm Weight up to 3 mt under the scope of supply  

  Universal couplings are parts to connect the sets of axis and to transfer movement and angular force of mechanical products. They are widely used for machinery of steel rolling mills, mining, metallurgical rolling, petrochemical, hoist lifting and wind power making turbines etc. They are classified into types of mechanical, hydraulic and electromagnetic. Mechanical type is the most common one. It is classified into rigid type, flexible type and safe type according to different standards & end user application Rigid type couplings have the main functions of connection and transmission, such as flanged type, sleeve type and clamping type, flexible type couplings have the main functions of connection, transmission, buffering and compensation, such as gear type, membrane type, chain type, universal type and non-metal flexible type.Safe couplings have functions not only as above mentioned, but also overload protection, such as ball type, friction type and pin connected type.     Advantage: Jai Bharat Castings is a coupling manufacturer, founded in 1977.Not only do we produce couplings, but also we are a comprehensive coupling company in designing, manufacturing and selling of couplings and spare and accessory parts. We produce kinds of unstandable couplings, at the same time, we also produce different kinds of standable coupling. The couplings are in high precision , low noise and vibration, long life and so on, we have a good reputation for our strict management, timely delivery and best quality along-with best service to our customers.
