SQD Series Single Rod Ball Joint Rod End Bearings
The SQD Series single rod ball joint rod end bearings feature an external male thread with a single straight rod body and spherical plain bearing construction. These open-type bearings are manufactured from carbon steel with zinc plating for corrosion resistance and are designed for applications requiring angular movement and force transmission. The inner ball is made from bearing steel with a hard chrome-plated spherical surface. Available in metric thread sizes from M5 to M16, with fine-thread variants ("-1" suffix) for precise adjustment needs. Left-hand thread versions are available by adding an "L" suffix to the bearing number.
