PHS Series Internal Thread Rod End Bearings
The PHS Series internal thread (female) rod end bearings are the counterpart to the POS Series, featuring a right-hand internal thread for direct mounting onto threaded shafts or studs. Like the POS Series, these bearings utilize a steel-on-bronze sliding contact surface with an embedded bronze liner for smooth articulation and reliable wear resistance. The rod end body is manufactured from carbon steel with an eco-friendly white zinc plating, while the inner ring (ball) is made from bearing steel with a hard chrome-plated spherical surface. These bearings can be lubricated through a grease nipple or via the rod end eye, and offer good radial load capacity. Available in bore sizes from 5mm to 30mm with metric internal threads, the PHS Series is ideal for linkages, control systems, agricultural equipment, and general machinery where a female rod end connection is required. Stainless steel versions are available upon request by adding an "S" prefix to the bearing number.
