Product Details
HARMONY Liner: Durable Mobility Solutions from China Suppliers & Factory - Wear-Resistant and Secure Locking Mechanism
Special Description
HARMONY Liner (Standard)
Germany UHMWPE
- 180° femoral head coverage maximizes range of motion
- The liner and cup surfaces match with tapered locking and high dome support to ensure maximum liner-to-cup contact, effectively transmitting force and reducing postoperative wear and debris
HARMONY Liner (10°)
Germany UHMWPE
- 180° femoral head coverage with a 10° liner matching 28 or 32 femoral heads increases the range of motion
- Maximized contact area with the femoral head effectively reduces postoperative wear
- Tapered locking between the liner and cup effectively transmits force while reducing wear
HARMONY Liner (10°)
Germany Highly Cross-linked PE
- Germany highly cross-linked polyethylene material with a 10-year clinical history
- Perfect cross-linking and anti-oxidation processes balance for high wear resistance and anti-aging, ensuring low postoperative wear
- Tapered locking between the liner and cup effectively transmits force while reducing wear
HARMONY Liner (Constrained)
Germany Highly Cross-linked PE
- Excellent head capture;
- Anti-rotation tap-scallop design between liner and shell.
- A chamfered titanium locking ring locks the liner into the HARMONY shell ;
- A titanium constraining ring locks the femoral head into the liner;

Frequently Asked Questions
Q: What materials are used to manufacture the HARMONY Liners?
HARMONY Liners are manufactured using premium Germany UHMWPE (Ultra-High-Molecular-Weight Polyethylene) and Germany Highly Cross-linked PE to ensure high wear resistance and anti-aging properties.
Q: How does the HARMONY Liner design maximize the range of motion?
The liners feature a 180° femoral head coverage design (with standard or 10° options) which optimizes head-to-liner contact and significantly increases the joint's range of motion.
Q: What mechanism is used to secure the liner inside the cup shell?
The system utilizes tapered locking and high dome support matching between the liner and cup surfaces to ensure maximum contact, effectively transmitting force and reducing postoperative wear.
Q: What makes the Constrained HARMONY Liner option unique?
The Constrained liner features excellent head capture, an anti-rotation tap-scallop design between the liner and shell, a titanium constraining ring to lock the femoral head, and a chamfered titanium locking ring to lock the liner into the shell.
Q: What sizes and femoral head diameters are compatible with these liners?
Depending on the specific liner model, they support femoral head diameters of 22mm, 28mm, 32mm, and 36mm with specifications ranging from outer diameters of 40mm up to 66mm.
