NHS Series — Female Thread Rod End Bearing Maintenance Free Pressed Body
17 bore sizes · d 3–40 mm · Pressed steel body · Female thread · PTFE composite liner
🆕 Series Overview
The NHS series is a compact maintenance-free rod end bearing with a pressed steel body and internal female thread. Pressed-body construction is lighter and more compact than a machined-body rod end for the same bore size, suited for light-to-medium duty linkages where space and weight are constrained.
Available in 17 bore sizes from 3 mm to 40 mm — covering miniature instrument linkages through medium industrial pivot applications. PTFE composite liner provides dry-running lubrication. Left-hand thread suffix L (e.g., NHS 18 L).
⚙ Key Design Features
Pressed Steel Body
Pressed construction: compact, lightweight envelope compared to machined-body SI series.
Maintenance-Free PTFE
PTFE composite liner. No re-lubrication required.
3 mm Minimum Bore
Smallest bore in the GBC rod end range for miniature linkage applications.
17 Bore Sizes
3 mm to 40 mm.
Compact Dimensions
Smaller overall length than equivalent-bore machined SI series.
Zinc-Plated Body
Electroplated zinc on pressed steel body.

🔭 Materials & Construction
Body: pressed carbon steel, zinc-plated. Inner ring: 100Cr6 hardened. Outer race: integral with pressed body; PTFE composite liner bonded to inner bore.
Pressed Steel Body
Formed from carbon steel sheet. Zinc-plated. Integral outer race.
PTFE Composite Liner
Bonded to inner bore. Dry-running.
100Cr6 Inner Ring
Hardened, ground spherical OD.
🏭 Typical Applications
Instrument Linkages
Control linkages in measuring instruments and laboratory equipment using 3–8 mm bore rod ends.
Light Actuators
Pneumatic cylinder rod ends and valve links in process control.
Consumer Products
Linkages in sports equipment, fitness machines, and consumer product assemblies.
Medical Devices
Positioning linkages in medical examination tables and rehabilitation equipment.
Electronics Equipment
Small-bore rod ends in PCB handling machines and inspection fixture links.
Automotive Control
Clutch and brake cable rod ends in motorcycles and light vehicles.
🔧 Installation & Maintenance
🔎 Thread Engagement
Minimum 1.0x nominal thread diameter engagement.
🔧 Load Limit
Do not exceed rated load for pressed-body design. Machined SI series provides higher ratings for same bore.
📈 Alignment
Align carefully — pressed body has lower stiffness under moment loads than machined body.
⚙ No Lubrication
PTFE liner provides dry running.
🌡 Temperature
PTFE -50 to +200 C. Zinc-plated pressed body +120 C practical limit.
✅ Replace on Wear
Replace when play develops.
