As a premier distributor and industrial bearing supplier across North-East India, Manglam Sales Corporation supplies genuine NBC 3215 Double Row Angular Contact Ball Bearings, manufactured by National Engineering Industries Ltd. (NEI). Engineered to handle heavy radial loads alongside simultaneous bidirectional axial thrust, this high-precision bearing features a 75 mm inner diameter (bore), 130 mm outer diameter, and 41.3 mm width. Designed to function with the tilting rigidity of a paired back-to-back single-row bearing set within a compact unit, it provides smooth rotational stability, precise axial guidance, and high load-carrying efficiency under demanding continuous duty cycles. Tailored to support Assam’s vital industrial sectors—including tea processing mills, oil refineries, petrochemical complexes, paper manufacturing, and heavy machinery operations—Manglam Sales Corporation guarantees authentic NBC products, competitive commercial pricing, complete documentation, and prompt dispatch across key industrial zones including Guwahati, Tinsukia, Dibrugarh, Jorhat, Bongaigaon, and Silchar.
Technical Specifications
Bore Diameter (Inner): 75 mm
Outer Diameter: 130 mm
Width / Thickness: 41.3 mm
Bearing Type: Double Row Angular Contact Ball Bearing
Contact Angle Design: Back-to-back layout providing high moment rigidity
Load Orientation: Combined heavy radial and double-direction axial (thrust) loads
Cage Construction: Pressed Steel / Polyamide
Key Operational Benefits
Bidirectional Thrust Management: Capable of accommodating heavy axial forces in both directions as well as high radial loads without requiring paired bearing arrangements.
Moment Rigidity & Compact Design: Offers superior tilt resistance and rigid shaft support within a streamlined, space-saving overall width.
Low Friction & Smooth Running: Precision-ground ball raceways ensure low operational torque, reduced heat generation, and extended service life.
High Operational Precision: Maintains tight radial and axial tolerances suitable for high-duty pumps, gearboxes, and processing equipment.
