Shanghai Yongxing Bearing Co., Ltd, a trusted professional manufacturer of high-precision rod end spherical plain bearings, provides customized rod end bearings with both right-hand (standard) and left-hand (reverse) external threads to meet diverse mechanical assembly and adjustment demands across automation, construction machinery, aerospace auxiliary equipment and hydraulic systems.
 
Right-hand (positive) external thread is our default mainstream specification. When observing the vertically placed thread, its thread ridge shows a higher profile on the right side. Following the right-hand grip rule, operators can rotate the bearing clockwise to screw it into matching mounting holes smoothly during installation. This standard thread suits most general scenarios, with universal interchangeability and abundant inventory support for fast delivery.
 
Left-hand (reverse) external thread features a left-higher thread ridge, which needs counter-clockwise rotation for screwing in. It is widely adopted in paired bidirectional tension structures, such as adjustable pull rod assemblies, to synchronously adjust pre-tightening force on both ends without dismantling components.
 
All our threaded rod ends are processed with strict CNC turning and surface anti-corrosion treatment, achieving precise thread tolerance and stable locking performance. Our engineering team can tailor thread pitch, diameter and length parameters, offering full technical guidance for thread identification and mounting to ensure optimal service life for your equipment
