INA AS150190 Thrust Roller Bearing Washer Chromium Steel 150mm ID

Description

Product Overview

The INA AS150190 thrust roller bearing washer is engineered to meet the demanding requirements of modern industrial power transmission systems. As part of INA’s extensive portfolio of high‑performance bearings, this washer offers a precise fit for axial needle and cylindrical roller assemblies, delivering consistent load distribution and reduced wear over extended service periods.

Manufactured from through‑hardened chromium steel, the washer benefits from exceptional hardness and resistance to deformation under heavy radial and axial loads. The material selection ensures that the component maintains its structural integrity even in environments with fluctuating temperatures and aggressive contaminants.

One of the defining design features of the AS150190 is its ground raceway. The precision‑ground surface reduces friction, enables higher rotational speeds, and improves overall running accuracy compared with unground raceways. This design choice translates directly into smoother operation and lower energy consumption for the end user.

Dimensionally, the washer measures 150 mm inner diameter, 190 mm outer diameter, and a width of 1 mm, providing a compact profile that can be integrated into tight mechanical assemblies without sacrificing load‑carrying capacity. The lightweight construction, weighing just 2.96 ounces, facilitates easier handling during installation and maintenance.

Compatibility is a key consideration for engineers selecting thrust washers. The AS150190 is specifically compatible with INA axial needle and cylindrical roller cage assemblies, making it an ideal choice when adjacent components cannot serve as raceways and precise centering is not a critical requirement.

Performance testing conducted by INA demonstrates that the washer can sustain high‑speed operation while maintaining dimensional stability. The combination of chromium steel hardness and ground raceway geometry results in a low wear rate, extending the service interval and reducing total cost of ownership for industrial applications.

Quality assurance processes at INA include rigorous heat‑treatment cycles, dimensional inspections, and surface finish verification. Each washer undergoes a comprehensive series of checks to confirm compliance with ISO 9001 standards, ensuring that every unit delivered meets the exacting specifications required by demanding industrial environments.

Packaging is designed for both protection and convenience. Washers are individually wrapped in anti‑static material and placed within a sturdy cardboard box that bears clear labeling, including part number, dimensions, and handling instructions. This approach minimizes the risk of damage during transit and simplifies inventory management for distributors and end users.

Usage

The AS150190 washer excels in applications where axial loads dominate, such as gearboxes, motor shafts, and conveyor drive systems. Its ability to function without the need for precise centering makes it suitable for installations where alignment tolerances are broader, reducing the need for costly precision machining of adjoining components.

In heavy‑duty manufacturing plants, the washer can be employed within high‑torque couplings that transmit power between motor and driven equipment. The chromium steel construction provides the necessary resilience to withstand shock loads and vibration, while the ground raceway ensures quiet operation even at elevated speeds.

For marine and offshore equipment, the corrosion‑resistant properties of chromium steel help protect the washer from saltwater exposure, extending its service life in harsh environments. The washer’s compact width also allows it to be used in confined spaces where larger bearing components would be impractical.

In the renewable energy sector, particularly wind turbine gearboxes, the AS150190 can be integrated into thrust bearing stacks to manage axial forces generated by blade loading. Its reliable performance under fluctuating loads contributes to the overall efficiency and reliability of the turbine system.

Maintenance crews benefit from the washer’s straightforward installation process. Because the component does not require precise centering, it can be fitted quickly using standard tools, reducing downtime during routine inspections or equipment overhauls.

When retrofitting older machinery, the AS150190 offers a cost‑effective upgrade path. Its compatibility with existing INA axial needle and cylindrical roller assemblies means that plant operators can replace worn washers without redesigning the entire bearing system.

FAQ

What load capacities can the INA AS150190 handle?

The AS150190 is rated for axial loads typical of medium‑size industrial gearboxes and motor shafts. Its chromium steel construction and ground raceway allow it to sustain high static and dynamic loads while maintaining dimensional stability. Specific load ratings are provided in the technical data sheet and should be matched to the application’s design requirements.

Can this washer be used with non‑INA bearing assemblies?

While the washer is optimized for INA axial needle and cylindrical roller cage assemblies, it can be compatible with other manufacturers’ components provided the dimensions and raceway geometry match. It is essential to verify that the inner and outer diameters, as well as the width, align with the partner bearing’s specifications to avoid premature wear.

How does the ground raceway improve performance?

The ground raceway creates a smoother surface that reduces friction between the washer and the rolling elements. This results in lower heat generation, higher rotational speeds, and improved accuracy of the bearing’s motion. The smoother interface also contributes to longer service intervals and reduced lubrication requirements.

What maintenance practices are recommended for this washer?

Regular inspection for signs of wear, corrosion, or debris accumulation is advised. Lubrication should follow the manufacturer’s guidelines, using compatible grease or oil types. Because the washer does not require precise centering, re‑installation is straightforward; however, care should be taken to avoid contaminating the raceway during handling.

Is the washer suitable for high‑temperature environments?

Chromium steel retains its hardness up to temperatures of approximately 300 °C (572 °F). For applications that exceed this range, additional cooling measures or alternative materials may be required. Always consult the technical data sheet and consider the operating temperature when selecting a bearing component.
