INA LS3552 Thrust Roller Bearing Washer Metric 35mm ID 52mm OD

Description

Product Overview

The INA LS3552 thrust roller bearing washer is a precision‑engineered component that fills a critical gap in axial bearing assemblies. Designed for metric applications, it measures 35 mm inner diameter, 52 mm outer diameter, and 3.5 mm width, providing a compact yet robust solution for a wide range of industrial machinery. The washer is fabricated from through‑hardened chromium steel, a material choice that delivers exceptional resistance to wear, deformation, and corrosion under heavy load conditions. Its ground raceway surface ensures smoother operation at higher speeds, reducing friction and extending the service life of the bearing system.

Unlike generic washers, this product does not rely on adjacent components to act as raceways, making it ideal for installations where precise centering is not required but reliable load distribution is essential. The through‑hardened chromium steel construction offers a hardness level that maintains dimensional stability even in demanding environments, such as high‑temperature factories or heavy‑duty power transmission setups. The ground raceway is finished to tight tolerances, delivering consistent rotational accuracy and minimizing vibration throughout the operational lifespan.

Manufactured by INA, a reputable brand known for its rigorous quality standards, the LS3552 washer undergoes comprehensive testing to verify compliance with industry specifications. Each unit is inspected for surface integrity, dimensional accuracy, and material composition, ensuring that every washer meets the exacting demands of modern industrial applications. The product’s compact form factor and robust material properties make it a versatile choice for a variety of equipment, from conveyor systems to heavy‑duty gearboxes.

In addition to its mechanical advantages, the washer’s design incorporates a simple yet effective geometry that facilitates easy installation and removal. The flat, concentric surfaces allow for straightforward alignment with other bearing components, reducing assembly time and minimizing the risk of misalignment. This user‑friendly design is especially valuable in maintenance scenarios where downtime must be kept to a minimum.

Overall, the INA LS3552 thrust roller bearing washer combines high‑grade materials, precise machining, and thoughtful engineering to deliver a product that meets the rigorous performance expectations of industrial users. Its durability, accuracy, and ease of use make it a reliable choice for anyone seeking to enhance the longevity and efficiency of axial bearing systems.

Usage

This washer is ideally suited for applications where axial loads are transmitted through needle or cylindrical roller assemblies, and where adjacent parts cannot serve as raceways. Typical environments include heavy‑duty industrial machinery, power transmission equipment, and high‑speed conveyor systems that demand consistent performance under continuous operation.

Engineers often select the LS3552 for installations that require a durable, low‑maintenance solution. Its hardened chromium steel composition ensures that the washer can withstand the abrasive forces generated by rotating rollers, making it an excellent choice for equipment that operates in dusty or corrosive atmospheres. The ground raceway further enhances its suitability for high‑speed applications, where reduced friction translates into smoother operation and lower energy consumption.

In addition to industrial settings, the washer can be employed in specialized equipment such as aerospace testing rigs, automotive manufacturing lines, and heavy‑equipment repair stations. Its metric dimensions align with international standards, facilitating seamless integration into globally sourced assemblies. The washer’s ability to function without relying on adjacent components for raceway support simplifies design considerations and reduces the need for additional machining or custom parts.

Maintenance personnel appreciate the washer’s straightforward installation process. Because the component does not require precise centering, it can be fitted quickly using standard tools, allowing for rapid turnaround during scheduled maintenance or unexpected repairs. The robust material properties also mean that the washer can endure repeated installation cycles without compromising its structural integrity.

FAQ

What size bearing assemblies is the LS3552 compatible with?

The LS3552 is engineered for metric axial assemblies that require a 35 mm inner diameter, 52 mm outer diameter, and a 3.5 mm width. It works well with both needle and cylindrical roller configurations where the surrounding components cannot act as raceways.

Can the washer be used in high‑temperature environments?

Yes. The through‑hardened chromium steel material retains its hardness and dimensional stability at elevated temperatures, making the LS3552 suitable for applications that experience significant heat buildup during operation.

Is the ground raceway necessary for all installations?

While the ground raceway enhances performance at higher speeds, the washer can still function effectively in lower‑speed applications. The ground surface simply provides an added level of smoothness and precision when needed.

What warranty does INA provide for this product?

INA offers a standard limited warranty that covers material defects and workmanship for a period of one year from the date of purchase. Additional support options are available through our technical service team.

How do I install the LS3552 washer correctly?

Installation is straightforward: align the flat surfaces with the corresponding bearing components, press the washer into place using standard hand tools, and verify that it sits evenly without gaps. No special centering equipment is required, and the design tolerates minor misalignments.
