NBC’s approach has always included dialogue with customers and an understanding of their needs. Solutions have gone beyond standard products and bearings to allied and specially designed and customized responses. Special and allied products are a natural consequence. This has also led to NBC being one of the very few manufacturers of very large diameter bearings in more than 200 sizes for railroad applications – axle boxes for wagons, traction motors and bearing components for passenger coaches. Large diameter bearings are also produced for steel plants and power generation plants. Self-aligning Spherical roller bearings are used in Meter Gauge, Broad Gauge and EMU Passenger coach wheel application. These bearings are used with axle box housing and end fittings. Cylindrical roller bearings are also used as Traction Motor armature bearings in Rail Locomotives. They are used in pairs and are both riveted and rivet-less.
NBC has produced Axle Boxes for the railways since 1952. The company meets the complete requirements of the Indian Railways (one of the largest in the world) by designing and developing Axle Boxes and bearings for fitment to locomotives manufactured by Diesel Locomotive Works, Chittaranjan Locomotive Works, various other wagon builders, ICF broad and meter gauge coaches. Over a million NBC bearings and boxes are in service with the Indian Railways. The development of completely indigenized Axle Boxes and bearings for the high speed Rajdhani Locomotive, and the Yugoslavian and Egyptian Railway wagons are the highlights of the design capabilities at NBC.
Cylindrical roller bearings are used mainly in Locomotives (Diesel or Electric) for Wagons wheel application. These bearings are used with axle box housing and end fittings.RANGE:
- Axle Boxes with Cylindrical Roller Bearing for Wagons ( 4 Inch Bore to 12.60 inch OD)
- Double Row Cylindrical Roller Bearing (Sealed Unit) (6.0 Inch Bore to 12.60 inch OD)
