Flexible Roller Bearing Manufacturers In kolkata

PRESSURE ROLLER UNITS (For Sinter Plant, Palletising Machine) JMC Pressure Roller Units are mainly developed for use in the continuous furnace of Sintering and Palletising plants. These ready to mount units are also suitable for all application where heavy loads are to be accommodated and the direction of rotation is frequently reversed. JMC Pressure Roller Units are basically double row full complement Cylindrical Roller Bearing. The very thick walled outer ring has three integral flanges. The highly wear - resistant outside diameter surface is cylindrical, being relieved towards the form of a chamfer. The Inner ring is in two halves, each of which has an integral flange, which is designed to enable the units to carry heavy axial loads in addition to radials. Oil seals inserted between the Inner ring flanges and Outer ring groove prevent contamination from entering the bearing and lubricating grease from leaving out and make the bearing as one solid integral unit. The Units are designed for maintenance free operation and should therefore not to be washed before mounting. In Contrast to normal rolling bearing where the outer ring is supported over its whole circumference by the housing bore, load is applied to the Pressure Roller units Via a small contact area on the outer ring Cylindrical surface. Deformation of the Outer ring values for the maximum permissible radial, dynamic and the static bearing loads are given in the table. The permissible Static load which can be applied to a Pressure roller unit is obtained from the smaller of the two values for C and Co.

UNIVERSAL JOINT JOURNAL CROSS ASSEMBLIES AND CROSS BEARINGS Contact us JMC CROSS Bearings are Cylindrical Roller Bearings with forged one piece bush, mainly used for heavy duty applications in steel plants and rolling mills. Oil sealing is properly done to avoid the lubricant losses and also to avoid the penetration of water or impurities, inside the Bearings. JMC UJ Cross Bearings can work : Under proper load with safety operations. Long rating life with free workmanship. Smooth running without vibration. JMC Journal Cross Assemblies can be supplied with Lubrication Systems : 1) Central Lubrication 2) Bush Lubrication (4 Point Lubrication) JMC Journal Cross Assemblies & Cross Bearings are lubricated with Lithium base Grease for ready to use. Apart from sizes mentioned in this catalogue we can manufacture Complete Journal Cross Assemblies and Cross Bearings as per customer requirements. Also we can refurbish the cross and make suitable bearings for the same. We may require one sample for development of new sizes.

ROLLER CAGE JMC Roller Cage Bearing with no inner and outer races are unique in design and versatile in application. The rollers running directly between the shaft and housing secure an appreciable saving in bearing size and weight. With the elimination of races the assembly is so simple that the roller cage slides between the shaft and housing easily, and runs firmly and freely. This phenomenon is achieved by the precision in the manufacture of Roller and their disposition in the cage. The liberal length of the rollers, their quantity in each assembly and their disposition increase the capacity of the bearing to carry heavy load and withstand shocks and misuse. JMC Roller Cage Bearing guarantees minimum frictional resistance, easy mounting, heavy load and smooth running. The rolling elements are machined out of special case hardening steel, heat - treated, to give a hard case, so as to withstand wear and tear, and a tough core to avoid breakage. High accuracy and smooth finish obtained in centreless grinding operation ensures long trouble - free running. The two end rings, made of medium carbon steel, located and held Parallel by a set of space bars form the cage. This plays a vital part in dispositioning the rollers for a smooth, silent, trouble - free continuous running. Unlike bush - bearing, ample space is left between the rolling elements for entry and supply of lubrication.
