Komatsu genuine tapered roller bearing-14X-27-11231

Core Features

Composite Load Bearing: Simultaneously withstands radial and bidirectional axial loads, adaptable to torque and axial movement conditions in transmission systems.

Positioning and Anti-Axis Movement: Axial displacement of the shaft is limited by the contact of inner and outer conical surfaces, ensuring transmission accuracy and component coaxiality.

Low-Resistance Transmission: Rolling friction replaces sliding friction, reducing energy consumption and adapting to low-speed, high-torque output under heavy loads.

Impact Buffering: The roller and cage structure disperses impact loads, resisting vibration and impact during bulldozer operation.

product Superiority

Original factory precision matching: Dimensions and mounting slots, shaft diameter tolerances are perfectly matched, allowing for direct replacement without adjustment, eliminating abnormal noise/wear caused by excessive clearance.

Materials and processes: Bearing steel (chromium steel) is quenched and tempered, with a surface hardness of HRC58–62. The cage is made of stamped steel plate/nylon, wear-resistant and deformation-resistant.

High load-bearing capacity: Rated dynamic load ≥120 kN, static load ≥150 kN, suitable for heavy-duty complex working conditions.

Maintenance-friendly: The detachable structure facilitates installation/disassembly; normal operating life ≥3000 hours, reducing downtime frequency.

High compatibility: Compatible with high-quality aftermarket parts, allowing for more flexible procurement and inventory.

Installation and Maintenance Points

Clean the shaft surface and bearing housing before installation to remove burrs, oil, and impurities to avoid scratching the raceways and rollers.

Install in pairs and apply appropriate preload to eliminate clearance and prevent movement and abnormal noise during operation.

The shaft surface roughness Ra ≤ 0.8 μm, free of scratches/rust, ensuring close contact between the rollers and the shaft surface.

Check for temperature rise/abnormal noise/clearance every 1000 hours, and replace the bearings every 3000 hours to prevent fatigue failure.

Fit scenarios and value

Suitable for: Rotating parts subjected to complex loads, such as final drives, gearboxes, and steering mechanisms; suitable for heavy-duty, dusty environments in mines and infrastructure projects.

Core benefits: Reduces transmission losses by approximately 10%, reduces component wear due to bearing failure, extends system life by approximately 25%, and lowers maintenance costs.
