Kubota U17 Mini Excavator Front Idler - 35MnB Roll Forged OEM Replacement with HRC45-55 Hardness for Mining Undercarriage

This professional OEM replacement front idler for Kubota U17 mini excavators is engineered to withstand the rigorous demands of harsh mining, construction, and heavy-duty working environments. As a critical undercarriage component for the Kubota U17—renowned for its compact design, zero-tail swing, boom offset function, and telescopic track variable frame—this front idler delivers exceptional performance in small-scale mining, narrow space operations, and earthmoving tasks.

Crafted from high-grade 35MnB alloy steel and processed via precision roll forging technology, this component offers superior structural density, enhanced tensile strength, and exceptional wear resistance. It effectively overcomes challenges from rock impact, gravel abrasion, and uneven terrain that often cause premature damage to conventional casting or simple forging parts.

Strictly adhering to Kubota U17 OEM dimensional specifications and undercarriage geometry, this front idler enables direct, modification-free installation, ensuring stable track tension, smooth guiding performance, and reliable undercarriage operation. Perfectly adapted to the Kubota U17's working characteristics—including telescopic variable frame (990mm contracted width, 1240mm expanded width), 1805kg operating weight, 230mm track width, and 12.1kW (16.4PS) D902-E4 engine with H*M*S three-pump hydraulic system—this front idler provides long-lasting durability while reducing downtime and maintenance costs.

Includes 12-month warranty and online after-sales support for worry-free operation.
