Import Genuine Cummins Kta19 Main Bearing Set Ar12270 — Buy in Bulk from Supplier in China

The Genuine Cummins KTA19 Main Bearing Set AR12270 is a factory‑made component designed for heavy‑duty diesel engines. It is produced by the CCEC Chongqing Cummins Engine Company and carries the Cummins part number AR12270. The set fits engine families KTA19, KTA38, M11 and NTA855, offering precise dimensional tolerances for reliable fitment. High‑grade alloy steel and exact bearing dimensions give the set superior load‑bearing capability.

In the engine‑parts market the bearing set follows typical specifications such as an inner diameter around 120 mm, outer diameter near 150 mm and a width of about 30 mm, which match standard KTA19 designs. The alloy‑steel construction is recognised for its wear resistance and ability to sustain loads up to roughly 250 kN, a figure common to OEM‑grade bearings. Each unit undergoes ISO‑9001‑based testing to verify dimensional accuracy and load performance, ensuring consistency across production batches.

The bearing set is most often installed in construction equipment, mining trucks and long‑haul transport vehicles, where engine reliability directly impacts operational uptime. Procurement agents for OEMs, fleet maintainers and aftermarket distributors typically request flexible MOQ and secure packaging, usually a sealed steel crate, with shipping terms such as FOB or CIF from the Chongqing port. The supplier states ISO certification and offers to provide test reports on request; buyers should confirm exact lead time, payment conditions and any additional documentation before placing an order.
