SQZ...-RS Series

SQZ...-RS Series Ball Joint Rod End Bearings - Low Maintenance, High Load Capacity

Product Features

• Self-Lubricating Design: Incorporates a PTFE liner between the ball and housing, eliminating the need for external lubrication and reducing maintenance frequency. This feature is particularly relevant for applications in inaccessible locations.
• High Static and Dynamic Load Ratings: Engineered to handle significant axial and radial loads, providing reliable performance in demanding mechanical systems. This design factor contributes to extended service life under continuous operation.
• Corrosion Resistance: The bearing housing is constructed from steel with a protective zinc coating, and the ball is made of bearing steel, offering resistance to common environmental corrosion.
• Precision Machining: The internal and external threads are manufactured to specific dimensional tolerances, ensuring a secure and precise fit with mating components.

Product Description

The SQZ...-RS series ball joint rod end bearings are manufactured in accordance with established industry standards. These components are designed for connecting moving parts in mechanical linkages and control systems, accommodating angular misalignment between a rod and a housing. They are characterized by a threaded male shank and a spherical ball with an integral bore. The bearings are suitable for applications requiring high reliability and minimal upkeep, such as in control levers, hydraulic cylinders, and steering mechanisms.

Application Areas

This product is suited for use in the following applications:

• Agricultural Machinery: Used in linkages for steering and implement control systems.
• Packaging Equipment: Integrates into automated machinery to manage motion and alignment.
• Industrial Robotics: Serves as a connection point in robotic arms to allow for complex movement.
• Automotive Suspension Components: Functions as a pivot point in suspension systems where angular motion and load transfer are critical.
• Construction Equipment: Applied in control linkages for excavators and loaders.

FAQ

1. How does the self-lubricating PTFE liner in SQZ-RS bearings compare to maintenance-intensive designs?

The integrated PTFE liner in the SQZ-RS series provides a low-friction interface, significantly reducing the need for continuous manual lubrication. In contrast, non-lined rod ends require periodic grease application to prevent wear and seizure, which can be a significant maintenance burden. For applications in difficult-to-access areas or environments where contamination from lubricants is a concern, the self-lubricating design offers a more reliable and streamlined solution. The choice between designs should be based on your specific operational environment and maintenance protocols. For a detailed comparative analysis, our technical team can provide a consultation.

2. Can these rod end bearings handle high-frequency vibrations without premature failure?

The SQZ-RS series is designed with robust materials and a tight-tolerance fit to manage operational vibrations and shock loads effectively. The strength of the housing and the precision of the spherical ball's fit ensure that the bearing maintains its integrity and prevents excessive play, which is a common cause of premature failure under high-vibration conditions. The bearings' static and dynamic load ratings provide a quantifiable measure of their capacity to withstand these forces. To ensure a long service life, it is crucial to select a bearing with load ratings that exceed the anticipated peak loads and vibrational stresses of your application. Our engineers are available to review your application's specific load and vibration profiles to recommend the most suitable product.
