These high-quality rod end bearings are designed to handle heavy loads with precision and durability. Featuring a 1/4" bore and 0.039" thread pitch, each bearing utilizes a self-lubricating joint to provide smooth rotation under stress. The stainless steel construction and threaded ball bearing interior allow full rotation in all directions, while resisting corrosion. Installing with the included jam nuts allows quick assembly and adjustment without tools. Ideal for applications requiring a robust spherical bearing that withstands vibration and impact. Each package contains two precision bearings that maintain close tolerances for consistent performance rep after rep.
