Title:
NUT (KU-1J54292500)
Description:
The Kubota nut (KU-1J54292500) is a precision-engineered flange hex nut (M8 x 1.25) designed to deliver secure and reliable fastening across a wide range of Kubota machinery. Its integrated flange distributes load evenly across the mounting surface, which reduces the risk of loosening under vibration and eliminates the need for a separate washer.
Because this nut operates in high-stress environments, Kubota manufactures it from durable, high-strength steel to ensure long-term resistance to wear, deformation, and corrosion. As a result, it maintains consistent clamping force even under heavy-duty applications such as construction, agricultural, and industrial operations.
Moreover, this component plays a critical role in maintaining the structural integrity of assemblies. It secures essential parts such as engine components, chassis fittings, loader linkages, and hydraulic mounts. Consequently, replacing worn or damaged nuts with the genuine KU-1J54292500 helps prevent component failure, improves safety, and ensures optimal machine performance.
Additionally, its OEM design guarantees precise thread engagement and proper torque retention, which simplifies installation and ensures compatibility with factory specifications.
Model Fitment:
The KU-1J54292500 flange nut fits an extensive range of Kubota machinery across multiple equipment categories, making it a widely used fastening component.
Compact & Mini Excavators
Commonly used in structural joints, engine mounts, and attachment assemblies:
- Kubota KX Series: KX040-4, KX057-4/5, KX080-4/5
- Kubota U Series: U48-5, U55-5
These machines rely on flange nuts to maintain secure connections in high-vibration digging and lifting operations.
Compact Track Loaders & Skid Steers
Used in frame assemblies, hydraulic systems, and loader linkages:
- SVL Series: SVL65-2, SVL75-2/3, SVL90-2, SVL95-2, SVL97-2/3
- SSV Series: SSV65 (multiple serial ranges)
These applications demand strong fastening to withstand continuous shock loads and heavy-duty cycles.
Compact & Utility Tractors (BX, L, LX, MX Series)
Installed across chassis, engine, and attachment mounting points:
- L Series: L3301, L3560, L3901, L4060, L4701, L6060
- LX Series: LX3310, LX3520, LX4020
- MX Series: MX4800, MX5200, MX5400, MX6000
These tractors use flange nuts extensively in both structural and serviceable assemblies.
Agricultural & Heavy-Duty Tractors (M Series)
Suitable for high-horsepower applications requiring durable fastening:
- M Series: M6040, M7060, M8540, M8560, M9540, M9960
- M5 / M6 / M7 Series tractors
These models require consistent clamping force to handle high torque and load conditions in field operations.
5. Engines & Power Units
Also used in Kubota diesel engines and industrial power units:
- V Series Engines: V2403, V2607, V3307, V3600
- Other industrial engine variants
This ensures secure mounting of engine components and ancillary systems.
