SQ..RS Series Angled Ball Joint Description

The SQ..RS Series is an angular ball joint bearing. The ball housing is made of zinc-based alloy through die-casting, equipped with left-hand or right-hand threads and built-in rubber seals. Adopting an angular structure design, it is specifically designed for angular linkage, light-medium load connection scenarios in equipment. The angular structure enables precise connection of equipment linkages at different angles without additional angle adapters. The ball allows flexible multi-angle swinging, and the rubber seal effectively protects against dust and moisture. With a simple structure, easy assembly, it is the preferred connector for angular linkages in general machinery and light industrial equipment.

Core Advantages

1. Angular structure eliminating the need for adapters

2. Zinc-based alloy housing for high wear resistance

3. Rubber seal for dust and water protection

4. Multi-angle swinging for flexible linkage

5. Cost-effectiveness with full specification coverage

Tips:
If the thread is left-hand (LH), the letter "L" must be appended to the bearing designation, e.g., SQL 6RS.
For products without a seal cover, the model designation is SQ...
