The KB‑A 400 bearing features a 4 inch (101.6 mm) bore, a 4.5 inch (114.3 mm) outside diameter and a width of 0.25 inch (6.35 mm). It is constructed from Chrome Steel grade GCr15, known locally as SUJ2, providing high hardness for demanding loads. Identified by SKU KB‑A400, the product is marketed for industrial machinery and equipment applications. The listing specifies a delivery window of five to ten days and notes a no‑return policy.
The chosen steel grade delivers typical hardness values of 60‑62 HRC, a common range for precision bearings used in high‑speed rotations. This model typically meets an ABEC‑5 tolerance, offering finer dimensional accuracy than smaller bearings. Standard lubrication is grease compatible with ISO‑VG 2, and the bearing is usually supplied as an open type, allowing optional sealing to be added downstream. Such specifications suit heavy‑duty gearboxes and agricultural equipment where load endurance is critical.
Target buyers include OEMs in automotive manufacturing, agricultural machinery assemblers and plant maintenance contractors who need reliable shaft support in confined spaces. Trade usually involves bulk palletised shipments, with the importer handling freight, insurance and customs duties. Prospective customers should confirm the exact material certification, packaging details and any optional sealing options with Kunal Bearings before confirming the purchase.

Validate the bore, outside diameter and width against your equipment drawings, and request a material test report confirming the GCr15 (SUJ2) grade. Ask the supplier to specify whether the bearings will be shipped with protective moisture barriers or anti‑corrosion coating, as this can affect storage conditions.
The listed delivery window is five to ten days, but you should agree on the Incoterm (e.g., FOB Ahmedabad or CIF Mumbai) and the payment schedule before confirming the order. Align these logistics terms with your freight forwarder to avoid unexpected costs or delays.
Consider arranging an independent inspection at the loading port to verify dimensions, hardness and material certification. Request accompanying documents such as a packing list, certificate of origin and any available test certificates to facilitate customs clearance in the destination country.
