HIRINTOL Cylinder Liner for Kubota D722 D722EBH D772B Wear Resistant

Description

Product Overview

The HIRINTOL cylinder liner is a precision‑engineered component designed specifically for Kubota D722, D722EBH and D772B engine families. Constructed from a high‑strength alloy that combines wear‑resistant and corrosion‑resistant properties, the liner provides a stable platform for piston movement while maintaining optimal compression ratios. The manufacturing process incorporates advanced casting techniques and rigorous quality control to ensure dimensional accuracy within micrometer tolerances, which translates into consistent performance across a wide range of operating conditions. The liner’s internal surface is finished to a fine texture that promotes efficient oil film formation, reducing friction and heat buildup during prolonged operation. In addition, the design includes optimized sealing grooves that enhance air and oil sealing, helping to preserve engine efficiency and extend service intervals. With a weight of approximately 6.6 pounds, the component is lightweight enough for easy handling yet robust enough to withstand the demanding forces encountered in heavy‑duty excavation and agricultural applications.

Usage

This cylinder liner is ideally suited for use in construction equipment such as the Kubota K008 mini‑excavator, Bobcat 316‑323 series, as well as a variety of Kubota tractors including the B7300HSD, B7400HSD, BX1800D, BX1850D, BX1860D, TG1860‑54, G1900, F1900, GF1800E and ZD18F models. The component excels in environments where engines are subjected to high loads, frequent start‑stop cycles, and exposure to dust, mud, and moisture. Whether operating on a job site, in a farm field, or in a remote construction zone, the liner’s wear‑resistant composition helps maintain engine power and fuel efficiency. Installation is straightforward thanks to the standardized dimensions that match OEM specifications, allowing technicians to replace the liner without extensive machine downtime. The product’s compatibility with a broad range of Kubota platforms also means that inventory management is simplified for dealers and service centers, reducing the need for multiple part numbers.
