Axial Bearing Washer INA Chromium Steel Ground Raceway

Description

Product Overview

The INA axial bearing washer is engineered for demanding industrial applications where precision and durability are paramount. Crafted from through‑hardened chromium steel, the washer offers exceptional resistance to wear, deformation, and corrosion, ensuring a long service life even under heavy axial loads. A ground raceway provides a smooth, low‑friction surface that supports higher rotational speeds and improves running accuracy compared with unground counterparts. The design eliminates the need for adjacent components to act as raceways, making it ideal for assemblies where space constraints or component geometry prevent traditional bearing configurations. Dimensions of 4.33 x 2.36 x 14.96 inches and a lightweight profile of 0.32 ounces allow for easy integration into compact machinery while maintaining structural integrity. Manufactured in the United States, each washer undergoes rigorous quality control to meet INA’s exacting standards, delivering consistent performance across a wide range of industrial and scientific equipment.

Usage

This axial bearing washer excels in environments where precise centering is not required but reliable load support is essential. Typical applications include needle bearing assemblies, cylindrical roller cages, and thrust roller systems found in automation equipment, robotics, and material handling machinery. The washer’s robust construction tolerates shock loads and vibration, making it suitable for high‑speed conveyors, CNC machines, and aerospace test rigs. Because the washer does not rely on adjacent parts for raceway function, it can be installed in retrofit projects where existing housings lack dedicated bearing seats. Engineers appreciate the ease of installation—simply place the washer between the bearing and housing, apply the specified preload, and the system operates smoothly. The product’s versatility also extends to custom prototype builds, where designers need a dependable bearing solution without committing to a full custom raceway.

FAQ

Can this washer be used with standard ball bearings?

While the washer is optimized for axial needle and cylindrical roller assemblies, it can be paired with standard ball bearings when the design does not require a dedicated raceway. The ground raceway provides a smooth surface that supports ball bearing operation, but users should verify load ratings and clearance requirements to ensure compatibility.

What is the maximum operating speed for this washer?

The ground raceway allows for higher rotational speeds compared to unground washers. In typical industrial applications, the washer can safely operate up to 10,000 RPM, provided that proper lubrication and preload are maintained. Exceeding this speed may reduce bearing life, so consult the equipment specifications for exact limits.

Is the washer suitable for corrosive environments?

Yes. The chromium steel material offers excellent corrosion resistance, making the washer appropriate for use in humid or chemically exposed settings. For extremely aggressive environments, additional protective coatings can be applied to further extend service life.

How do I determine the correct preload for installation?

Preload should be set according to the manufacturer’s guidelines for the specific bearing assembly. Generally, a light to moderate preload ensures optimal performance without excessive friction. Use calibrated torque tools and follow the recommended torque values to achieve consistent results across multiple installations.
