The PHS Series Rod End Bearing (also known as a Heim joint or rose joint) is an articulating mechanical articulating joint. It consists of a spherical inner ring with a cylindrical bore for shaft mounting, housed within an eye-shaped head that features an internal (female) threaded shank. This design allows for angular misalignment between connected parts, making it ideal for mechanisms that require smooth transmission of static and dynamic forces under oscillating or tilting conditions.
We supply the complete PHS metric range from PHS5 to PHS30. Below are the precise technical dimensions for our most popular sizes, PHS6 and PHS14:
Specification | PHS6 (6 mm) | PHS14 (14 mm) |
Bore Diameter (d) | 6 mm | 14 mm |
Female Thread (d3) | M6 × 1.0 | M14 × 2.0 |
Housing Head OD (d2max) | 20 mm | 36 mm |
Inner Ring Width (B) | 9 mm | 19 mm |
Housing Width (C1) | 6.75 mm | 13.5 mm |
Thread Length (L3min) | 14 mm | 27 mm |
Center to End Length (h1) | 30 mm | 57 mm |
Weight | 26 g | 161 g |
(Note: Data derived from standard PHS series engineering tables. Please contact us for dimensions of other sizes like PHS8, PHS10, PHS20, etc.)
To meet the diverse demands of different operating environments, we offer deep customization:
Housing & Ball Materials: Choose from economical Carbon Steel, high-durability Chrome Steel (GCr15), or anti-corrosive Stainless Steel for marine/food-grade applications.
Precision Ratings: Available from standard P0 (ABEC-1) up to ultra-high precision P2 (ABEC-9).
Lubrication: Factory packed with your required grease (e.g., SRL, PS2, Alvania R12) to match your machine's temperature and speed profiles.
Clearance & Vibration: Internal clearances from C0 to C5, and vibration grades Z1V1 to Z3V3 available upon request.
Because they efficiently handle angular misalignment, PHS rod ends are heavily utilized across various B2B sectors:
Automotive: Steering linkages, tie rods, and suspension control arms.
Automation & CNC: Robotic arms, pneumatic cylinders, and linear actuator mounts.
Heavy Machinery: Agricultural tractors, textile machinery, and water pump linkages.
We are an ISO-compliant, CE/ROHS/SGS certified manufacturer dedicated to global supply chain excellence.
OEM / ODM Service: We offer complete Buyer Label services and can manufacture non-standard threads or sizes based on your technical drawings.
Packaging: Highly flexible. Choose from bulk plastic tubes, industrial cartons, or heavy-duty wooden cases for large ocean freight shipments.
Delivery: Fast turnaround of 5–15 days.
Payment Terms: 100% T/T, 30% deposit with balance before shipping, L/C at sight, PayPal, and Western Union.
Q1: What does "PHS" stand for?
A: "PHS" is the standard industry designation for a metric rod end bearing with a Female (internal) right-hand thread. If you require a Male (external) thread, please ask for our POS series catalog.
Q2: Does the PHS14 use a standard or fine thread?
A: The standard PHS14 features an M14 × 2.0 thread. If your application requires a fine thread pitch (e.g., M14 × 1.5), we can manufacture this via our OEM/ODM service.
Q3: Are these rod ends maintenance-free?
A: We offer both maintenance-requiring types (steel-on-steel or steel-on-bronze, which feature a grease zerk fitting) and maintenance-free types (using PTFE/Nylon composite liners). Please specify your preference when requesting a quote.
