HD Switch 3-Pack Concave Belleville Washers for ExMark Fork Bearings

Description

Product Overview

HD Switch delivers a 3‑Pack of concave Belleville spring washers designed specifically for ExMark caster fork bearings. The washers feature a precision‑engineered concave shape that provides consistent preload and reliable tension across a wide range of operating conditions. Built with hardened steel, each washer offers superior resistance to fatigue, ensuring long‑term performance in demanding applications such as lawn mowers and industrial equipment.

The material selection focuses on high‑grade alloy steel that meets ASTM standards for hardness and tensile strength. Heat‑treated to a Rockwell hardness of 55‑60, the washers maintain their spring characteristics even after repeated compression cycles. This durability reduces the need for frequent replacements, saving both time and maintenance costs for professional users.

Package dimensions measure 1.5 x 1.5 x 1.5 inches and weigh just 0.96 ounces, making the set lightweight yet robust. The compact packaging includes three identical washers, each stamped with the model number 1‑633508, ensuring easy identification and inventory management for service technicians and parts distributors.

Compatibility is extensive, covering a broad spectrum of Lazer Z, CT, LC, S‑Series, DS, E‑Series, HP, and X‑Series models. The washers fit part numbers such as LZ18KC523, LCT21BV523, LZDS902K605, LZE20KA484, LHP19KA465, and LZX23KC486, among many others. This wide fit range eliminates the need to stock multiple part numbers, streamlining supply chains for retailers and repair shops.

Performance testing shows that the concave design delivers up to 15% higher load‑carrying capacity compared to flat washers, while maintaining a low profile that fits within tight bearing housings. The washers also provide excellent vibration damping, reducing noise and wear on adjacent components during operation.

Overall, the HD Switch 3‑Pack offers a reliable, high‑quality solution for anyone needing to restore or upgrade caster fork bearings. Its combination of material strength, precise geometry, and broad compatibility makes it a preferred choice for both OEMs and aftermarket service providers.

Usage

These washers are ideal for routine maintenance of ExMark lawn mower caster forks, where precise tension is critical to wheel alignment and steering stability. Technicians can quickly replace worn washers to restore proper bearing preload, ensuring smooth operation and extending the life of the mower’s drivetrain.

In industrial settings, the washers serve as reliable tensioning components for conveyor rollers, material handling equipment, and other machinery that utilizes caster forks. Their hardened steel construction tolerates heavy loads and harsh environments, making them suitable for factories, warehouses, and outdoor applications.

When installing, the concave shape allows the washer to compress evenly, providing a uniform load distribution that minimizes point stress on the bearing race. This results in reduced wear on both the bearing and the shaft, contributing to longer service intervals and lower total cost of ownership.

For DIY enthusiasts and professional mechanics alike, the 3‑Pack offers a convenient solution for multiple bearing repairs in a single purchase. The washers can be used in both new assemblies and retrofits, offering flexibility for a variety of repair scenarios.

Because the washers are lightweight yet robust, they can be handled easily without special tools, speeding up the installation process. Their compact size also allows for storage in standard parts bins, keeping workstations organized and efficient.
