Female rod end bearings are rod ends featuring female, or internal, threads, that can be left or right hand. Rod end bearings
comprise an eye-shaped head with integral shank, forming a spherical plain bearing housing unit; they are commonly used in applications where an articulating joint is required, such as aircraft control systems, steering links, and track rollers. Some rod ends may include the bearing, or just the inner ring with or without a sliding layer between the head and the ring. Female or internal threads are used in specific applications such as helicopter blade adjustments. These bearings are available in a variety of material combinations for the sliding contact surface, such as steel-on-steel, steel-on-bronze, and steel-on-PTFE fabric or composite material. steel-on-steel and steel-on-bronze rod ends require regular republication, however they are wear-resistant and perform well under lubricant starvation conditions. Steel types include low carbon, heat treated alloy and stainless steel. They are highly suitable for applications with heavy alternating loads. Rod ends featuring PTFE are no maintenance bearings and do not require lubrication
; this offers extended operating life, and is suitable for applications with heavy loads in a constant direction. Contact our experts at MRO Supply for information about which female rod end bearing suits your application.
