SQ-RS Series Bent Rod Type Rod End Bearings
The SQ-RS Series bent rod type rod end bearings feature a right-hand external thread with a bent rod body, ideal for applications requiring angular movement, offset connections, or compact installations. These bearings are equipped with double-lip RS (Rubber Seal) seals that provide excellent protection against dust, moisture, and contaminants, extending service life in demanding environments. The rod end body is manufactured from carbon steel with eco-friendly white zinc plating for corrosion resistance, while the inner ring (ball) is made from bearing steel with a hard chrome-plated spherical surface. Available in metric thread sizes from M5 to M22, with fine-thread variants ("-1" suffix) for precise adjustment needs. Stainless steel versions are available upon request by adding an "S" prefix to the bearing number.
