Import Ball With Cut — Buy in Bulk from Supplier in India

The Ball with cut from Eastman Industries Ltd. is a tractor linkage ball, specifically a top link ball, lower link ball, or guide core ball used in three-point hitch assemblies on agricultural tractors. These components are precision-machined from industrial-grade carbon or alloy steel, with dimensions engineered to fit standard Category 1, 2, and 3 hitch specifications. The cut refers to the machined groove or recess that engages with the implement pin or retaining mechanism, a critical feature for secure attachment under dynamic load. Surface finish is corrosion-resistant, typically zinc phosphate or zinc plating, to withstand outdoor exposure during field operations.

Material specification for this grade of linkage ball typically falls within AISI 1045 or equivalent medium-carbon steel, induction-hardened at the ball surface to resist wear from articulation. The dimensional tolerances for ball diameter, shank diameter, and cut width must conform to ASAE S203.10 or OEM interchange standards to ensure compatibility across tractor brands. Multiple sizes are offered to match diverse machinery requirements, though exact SKU dimensions require confirmation with Eastman Industries. The heat treatment process, typically through-hardening or surface induction, determines fatigue life under cyclic loading conditions common in tillage and cultivation work.

Primary applications span agricultural tractors, seeders, ploughs, harrows, and mounted sprayers where three-point hitch articulation is required. Construction and municipal equipment using similar linkage geometry also represent secondary markets. Buyers should confirm the specific ball category (top link, lower link, or guide core), the nominal diameter and cut dimensions, and whether the supplier provides dimensional test reports or batch material certificates. Eastman Industries is located in Ludhiana, Punjab, a major hub for Indian agricultural implement manufacturing, which supports component sourcing infrastructure but does not itself guarantee product specification.

Eastman Industries Ltd. is located at C-87, Phase-V, Focal Point, Ludhiana 141010, Punjab, India. The company holds a harbor trust tier and imported supplier tier on the platform, though the response rate is recorded at 0.00% with zero average response hours. Ludhiana is a recognised centre for agricultural machinery and component manufacturing in India, providing access to steel supply, machining subcontractors, and surface treatment facilities.

The source description mentions ISO and SGS certifications, though no certificate numbers or scopes are provided and should be verified directly with the supplier. No information is given about year of establishment, production capacity, in-house heat treatment capability, or export experience. The platform description contains generic marketing language that appears partially templated, so buyers should request specific product drawings, material certificates, and quality test reports for the exact ball variant under consideration.
