HARFINGTON Thrust Ball Bearings 8mm Bore 22mm OD Chrome Steel Washers

Description

Product Overview

HARFINGTON delivers a precision‑engineered miniature thrust ball bearing series designed for demanding industrial applications. Each bearing features an 8 mm bore, a 22 mm outer diameter, and a 7 mm thickness, providing a compact footprint while maintaining robust load‑carrying capacity. Constructed from AISI 52100 chrome steel, the rolling elements exhibit exceptional wear resistance, high hardness, and superior performance at elevated temperatures. The bearing incorporates a brass cage that securely positions the balls, reducing friction and extending service life. Included with each unit are matching steel washers that simplify installation and ensure proper alignment within the assembly.

The design focuses on axial load handling, offering a static load rating of 2.8 kN and a limiting speed of up to 3 500 rpm when lubricated with oil, or 2 000 rpm with grease. This makes the bearings ideal for low‑speed, high‑torque environments where axial forces dominate. The compact geometry enables integration into tight spaces such as conveyor rollers, packaging equipment shafts, and machine tool spindles without compromising performance.

Material selection and heat treatment processes are optimized to deliver consistent dimensional stability and dimensional tolerance across the entire batch. The chrome steel balls are precision‑ground to achieve a smooth surface finish, minimizing vibration and noise during operation. The brass cage provides corrosion resistance and reduces the risk of galling, especially in applications where the bearing may be exposed to moisture or chemical contaminants.

To further enhance reliability, each bearing is supplied with a set of stainless‑steel washers that distribute load evenly across the housing surfaces. This reduces localized stress concentrations and helps prevent premature wear of the mating components. The washers also simplify the assembly process, allowing technicians to install the bearing quickly and securely, which is especially valuable in high‑volume manufacturing settings.

Usage

These thrust ball bearings excel in conveyor system applications where axial loads are prevalent, such as belt drives, roller conveyors, and chain drives. Their compact size allows them to be mounted directly onto shafts or within bearing housings, providing smooth rotation and reliable load support. The high static load capacity ensures that the bearing can handle sudden load spikes without deformation, making it suitable for heavy‑duty material handling equipment.

In packaging equipment, the bearings are frequently used in rotary tables, turntables, and feed rollers that require precise positioning and consistent speed control. The low friction characteristics of the chrome steel balls, combined with the brass cage, enable smooth operation at the moderate speeds typical of packaging lines, reducing wear on adjacent components and extending overall system lifespan.

Machine tools benefit from the bearing’s ability to sustain axial loads in applications such as spindle mounts, tool changers, and auxiliary shafts. The bearing’s high hardness and temperature resistance allow it to operate reliably in environments where heat generation is a concern, such as during high‑speed machining or when cutting fluids are present. The included washers facilitate easy retrofitting into existing equipment, minimizing downtime during maintenance or upgrades.

Beyond these primary uses, the bearings are also suitable for specialized applications like oven turntables, pump shafts, and rotating platforms where axial forces dominate and space constraints demand a compact solution. Proper lubrication—whether grease or oil—combined with regular inspection ensures optimal performance and longevity across all these diverse use cases.
