F-86677 Needle Roller Loader Gearbox Bearing 75x83x16mm

Product Name: F-86677 Needle Roller Loader Gearbox Bearing 75×83×16 mm

Product Description

The F-86677 is a high‑performance needle roller bearing designed specifically for heavy‑duty gearbox applications, particularly in construction machinery and loaders. With a compact outer dimension of 75 mm (bore) × 83 mm (O.D.) × 16 mm (width), this bearing offers a single‑row, open‑type configuration without an inner ring. The absence of an inner ring allows the shaft itself to serve as the raceway, enabling a more compact design and higher load‑carrying capacity within limited radial space.

This full‑complement needle roller bearing (no cage) maximizes the number of rollers, providing exceptional radial rigidity and shock load resistance – ideal for automotive gearboxes and industrial transmission systems where space is constrained but reliability is critical

Key Features

• Inner‑ring‑less design – allows direct mounting on the hardened shaft, reducing overall assembly size and weight.

• Full complement of rollers – no cage means more rolling elements, significantly increasing radial load capacity and stiffness.

• C3 internal clearance – accommodates thermal expansion and ensures stable operation under varying temperature and load conditions.

• P0 precision class – meets standard industrial requirements for general gearbox applications.

• Compact dimensions – 75×83×16 mm, ideal for space‑limited gearbox layouts.

• Open construction – compatible with oil or grease lubrication systems, easy to maintain.

• High shock resistance – specially suited for loaders and off‑highway vehicles that experience frequent impact loads.
