INA Thrust Roller Bearing Washer 110mm ID x 145mm OD, 7mm Width

Description

Product Overview

The INA LS110145 thrust roller bearing washer is a precision‑engineered component designed to meet the demanding requirements of modern industrial power transmission systems. Constructed from through‑hardened chromium steel, the washer delivers exceptional resistance to wear, deformation, and fatigue, ensuring long‑term reliability even under heavy axial loads. Its dimensions—110 mm inner diameter, 145 mm outer diameter, and a 7 mm width—provide a robust load‑bearing surface that integrates seamlessly with INA axial needle or cylindrical roller assemblies.

Each washer features a ground raceway that enhances rotational accuracy and reduces vibration, delivering smoother operation compared with unground alternatives. The material selection and heat‑treatment processes are optimized to maintain dimensional stability across a wide temperature range, making the product suitable for environments that experience temperature fluctuations and high‑stress cycles. The washer’s design eliminates the need for adjacent components to serve as raceways, simplifying installation and reducing the risk of misalignment.

Usage

Designed for a broad spectrum of axial bearing applications, this thrust roller bearing washer excels in machinery where precise centering is not a critical requirement but durability and load‑carrying capacity are paramount. Typical installations include heavy‑duty conveyors, gearboxes, industrial presses, and large‑scale manufacturing equipment that demand consistent thrust support. The washer’s robust construction makes it ideal for use in high‑speed rotating equipment, where the ground raceway contributes to reduced friction and extended service intervals.

In addition to traditional industrial settings, the LS110145 is well‑suited for renewable energy installations such as wind turbine gearboxes, where axial loads can be significant and reliability is essential. Its corrosion‑resistant chromium steel composition also makes it a viable choice for marine and offshore applications, where exposure to moisture and salt can accelerate wear on lesser‑quality components.
