🎯 Product Introduction & Core Features
PHS, POS, PHSA, POSA, SAT/K, SIT/K series rod end bearings (also called rose joints, ball joint bearings, articulated rod ends) consist of outer housing + spherical plain bearing insert, with external thread and internal thread two main structures. The self-lubricating composite sliding surface provides low friction, strong self-aligning ability, can bear radial + bidirectional axial composite loads, absorb assembly deflection and equipment vibration. Available standard short body / extended long body / tapered bore SAT/K variants, widely stocked for industrial hydraulic cylinders, automation equipment, farm machinery, construction vehicles and packaging lines. Multiple thread sizes from 3mm to 30mm in full specifications.

Frequently Asked Questions About Rod End Rose Joint Bearings
1. Difference between PHS and POS rod end?
PHS is external thread rod bearing, used to screw into mounting base; POS is internal thread, install on threaded straight shaft. Both standard short housing for regular swing stroke equipment.
(Español: PHS rosca exterior, POS rosca interior, versión corta estándar.)
2. What is PHSA / POSA long type used for?
PHSA & POSA adopt extended longer housing, larger maximum swing angle ±10~13°, suitable for hydraulic cylinders with long travel stroke and equipment needing big deflection space.
3. What does suffix K mean on SAT/K SIT/K bearings?
K stands for 1:12 tapered inner bore, tightly lock the mounting shaft under frequent vibration, prevent inner ring slipping, ideal for mining, tractor and construction machinery with continuous shock load.
4. Are these rod ends self-lubricating?
All PHS/POS/PHSA/POSA/SAT/K series are equipped composite self-lubricating sliding liner, no frequent grease filling required, save maintenance cost for outdoor farm & construction equipment.
5. Can I mix different series & sizes in one wholesale order?
Yes, mixed batch order supported, small quantity sample orders acceptable. All thread sizes M3-M30 full stock for fast shipment within 3-7 working days.
