More Than a Supplier — Your Reliable Bearing Partner.
The SQZ..RS Series is a straight 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 to effectively prevent dust and moisture ingress. The ball and housing feature high fit precision, enabling flexible multi-angle swinging. Specifically designed for straight linkage, light-medium load connection scenarios in equipment, it has a simple structure, easy assembly, and moderate cost. Compatible with a wide range of metric threads, it is a basic connector for straight linkages in general machinery and light industrial equipment.

Tips:
If the spherical head housing has a left-hand thread, the bearing designation must include the letter "L", e.g., SQZL 6RS.
For products without a seal cover, the model designation is SQZ...
