SQZ...RS Series — Sealed Straight Ball Joint with Female Thread
14 bore sizes · d 5–35 mm · Female thread · Zinc-base alloy housing · Rubber dust seal
🆕 Series Overview
The SQZ...RS series is a straight-joint ball joint with an internal female thread on the zinc-base alloy housing. The ball element allows angular and oscillating motion in control rod, throttle, and linkage applications. RS suffix indicates rubber dust seal construction.
Available in 14 bore sizes from 5 mm to 35 mm. Unsealed variant designated SQZ (no RS suffix). Left-hand thread suffix L (e.g., SQL 6RS). Zinc-base alloy housing provides corrosion resistance and lower weight than steel housing rod ends.
⚙ Key Design Features
Ball Joint Construction
Ball element in zinc-base alloy housing allows angular and oscillating motion in multiple planes.
Rubber Dust Seal
RS designation: rubber dust seal excludes contamination from ball contact surface.
Zinc-Base Alloy Housing
Corrosion-resistant and lighter than steel housings.
Female Thread
Internal thread for connection to male-threaded control rods and cable ends.
14 Bore Sizes
5 mm to 35 mm for light to medium control linkage applications.
Left/Right Thread
Standard right-hand thread. Left-hand with suffix L.

🔭 Materials & Construction
Housing: zinc-base alloy (Zamak-type). Ball: hardened steel. Dust seal: rubber NBR. Direct ball-in-socket construction against zinc housing bore.
Zinc-Base Alloy Housing
Corrosion-resistant, lightweight. Direct ball contact against housing bore.
Hardened Steel Ball
Provides the angular motion element.
Rubber Dust Seal
Excludes contamination from ball contact surface.
🏭 Typical Applications
Throttle and Brake Cables
Barrel-end connections and cable rod ends in motorcycle and small engine control systems.
HVAC Damper Controls
Straight-joint ball joints for damper actuator rod connections in building services.
Agricultural Control Linkages
PTO clutch engagement and implement depth control linkages on tractors.
Automotive Trim Mechanisms
Gear selector cable ends, bonnet latch rods, and convertible roof linkage connections.
Industrial Control Rods
Valve actuator and gate control rod end connections in water treatment and process piping.
Fitness Equipment
Cable adjustment and resistance linkage ball joints in exercise machines.
🔧 Installation & Maintenance
🔎 Thread Engagement
Minimum 1.0x nominal diameter. Thread-lock under vibration.
🔧 No Re-lubrication
SQZ ball joints have no lubrication hole. Zinc-alloy and steel contact is self-lubricating for normal oscillating conditions.
📈 Load Limit
Do not exceed rated radial load. Contact GBC for combined load cases.
⚙ Seal Inspection
Inspect rubber dust seal at maintenance intervals. Replace bearing if seal is damaged.
🌡 Temperature
-20 to +80 C for NBR rubber seal.
✅ Replace on Wear
Replace when detectable play or stiff movement develops. Not field-serviceable.
