Detailed Description

The 13F-Z27-2260 BEARING KOMATSU plays a crucial role in enabling rotational and oscillating motion between two moving parts in heavy-duty excavators and wheel loaders. Bearings like this are vital for maintaining alignment and reducing metal-to-metal contact under high pressure and uneven loads—ensuring smooth articulation of boom arms, buckets, and steering joints.

This particular model is manufactured from premium-grade alloy steel and finished with precision grinding techniques to offer maximum dimensional stability. Its spherical contour supports angular movement without compromising structural integrity, making it perfect for use in Komatsu machinery where both axial and radial loads are applied.

The spherical geometry enhances its load-carrying capability, while also distributing force evenly across its contact surface—minimizing localized stress and wear. This results in extended maintenance intervals, reduced vibration, and greater operational safety.

Machined to exacting OEM tolerances, the 13F-Z27-2260 BEARING KOMATSU guarantees a seamless fit in replacement scenarios, minimizing installation time and eliminating unnecessary field modifications.

Role in KOMATSU Equipment

In high-performance hydraulic systems, the bearing supports linear and rotary motion in structural joints and connections. Without reliable bearings, heavy machinery suffers from excessive vibration, premature joint wear, and mechanical inefficiency. The 13F-Z27-2260 BEARING KOMATSU helps maintain alignment between connected parts—protecting shafts and pins from metal-to-metal abrasion and ensuring smooth pivoting action in hydraulic cylinders and swing arms.

Its resistance to extreme loading and environmental wear also makes it indispensable for operations involving repetitive motion, heavy impact, or long duty cycles such as mining, construction, and quarrying.

Maintenance and Replacement

• Inspection Interval: Every 500–1000 operating hours (depending on application)

• Signs of Wear: Looseness, abnormal vibration, excess noise, or leakage at the joint

• Replacement Tip: Always clean housing surfaces thoroughly before pressing in the new bearing

• Lubrication Advice: Apply grease through designated fittings; avoid contamination during servicing

• Installation Method: Press-fit recommended for best seating; do not hammer into position

3GEN Export stocks the 13F-Z27-2260 in bulk quantities, making same-day processing and dispatch available for most orders. We also provide support for installation and maintenance best practices.
