Import Bearing Wires — Buy in wholesale FOB from Supplier in India

Mannohar Lal Hira Lal Limited produces phosphated bearing wire in coil form, engineered specifically for cold heading operations in the manufacture of bearing rolling elements. The material specification cites high-carbon chromium bearing steel conforming to EN31 / SAE 52100, with carbon content 0.98-1.10% and chromium 1.30-1.60%, supplied in spheroidised annealed condition to enable deformation without cracking during header forming. Wire diameter range spans 1.60mm to 9.50mm, with phosphated surface treatment providing lubricant retention and reduced die wear during cold forging of balls, rollers, taper rollers, and cylindrical rollers. The phosphating process creates a crystalline zinc or manganese phosphate layer, typically 4-8 g/m² coating weight, that acts as a solid lubricant carrier during severe plastic deformation in multi-station headers.

The spheroidised annealed microstructure, described as uniformly distributed fine carbide globules in a ferrite matrix, represents the critical quality parameter for cold heading feedstock. This microstructure yields tensile strength typically 600-750 MPa and hardness 160-220 HB, balancing sufficient yield strength for die filling with adequate ductility for reduction ratios up to 60% in single blow without central burst or surface cracking. The chromium addition provides through-hardening response and temper resistance, essential for bearing components subjected to Hertzian contact stresses in service. Dimensional tolerance, coil weight, and tensile strength are maintained per customer specification, indicating capability for tailored production rather than purely standard stock. Finished drawn wire receives rust preventive oil dip, four-point binding, and dual-layer wrapping in polyethylene and hessian or HDPE for corrosion protection during storage and transport from their Ghaziabad facility.

Primary applications encompass the full spectrum of bearing rolling elements: spherical balls for deep groove and angular contact bearings, cylindrical rollers for NU and NJ series roller bearings, taper rollers for automotive and heavy equipment tapered roller bearings, and needle rollers for drawn cup and cage assemblies. Buyers include OEM bearing manufacturers, tier-one automotive suppliers, and specialised cold forgers serving the replacement bearing market. The Indian origin offers geographic diversification for buyers seeking to reduce dependence on Chinese or European wire sources, though buyers should confirm whether the material is continuously cast or ingot cast, as this affects inclusion content and fatigue performance. Import considerations include verifying that the spheroidise anneal cycle, phosphate coating weight, and oil film thickness meet your header equipment specifications and end-customer bearing steel approval requirements.

Mannohar Lal Hira Lal Limited is located at 23 Naya Ganj, Ghaziabad 201009, Uttar Pradesh, India. The supplier holds a harbor trust tier classification, with response rate and average response hours both recorded at zero in available data. The company specialises in bearing wires for cold heading applications, with particular focus on phosphated high-carbon chromium steel wire for rolling element manufacture. Their facility in Ghaziabad sits within the Delhi National Capital Region industrial corridor, with access to steel rolling and wire drawing infrastructure in the northern Indian manufacturing belt.

The listing does not disclose establishment date, ownership structure, annual turnover, workforce size, production capacity in tonnes, or specific domestic and export client names. No quality management system certifications, laboratory accreditation, or automotive industry approvals are mentioned. The custom specification and source description provide technical detail but omit commercial specifics such as standard coil weights, maximum coil diameter, or reel specifications. Buyers should request direct disclosure of ISO 9001 or IATF 16949 certification, material approval status with major bearing manufacturers, and capability for statistical process control on wire diameter and tensile strength. A factory assessment focusing on spheroidising furnace control, phosphate line calibration, and coil handling equipment would support supplier qualification for critical bearing applications.
