GIHN-K...LO Series — Rod End Housing with Locking Nuts Long Design Maintenance Required
14 bore sizes · d 12–125 mm · Long design · Locking nuts · GE..LO insert
🆕 Series Overview
The GIHN-K..LO series is the long-design (LO) locking-nut rod end housing, providing a longer housing body than GIHR..DO to accommodate the extended GE..LO spherical plain bearing insert. The greater bearing span significantly increases the moment load capacity compared to the standard-length GIHR for the same bore.
Available in 14 bore sizes from 12 mm to 125 mm. The locking slot nut and locking screw clamp the GE..LO insert outer ring for positive retention under high load and vibration. Left-hand thread suffix L.

⚙ Key Design Features
Long Design LO
Extended housing length accommodates the GE..LO long spherical plain insert — significantly higher moment load capacity than standard GIHR for the same bore.
Locking Slot Nut
Slot nut and locking screw provide positive outer ring retention under high load and vibration.
GE..LO Long Insert
Extended-length spherical plain bearing for maximum load distribution along the housing bore.
Grease Nipple
Lubrication hole and nipple for in-situ insert re-lubrication.
14 Bore Sizes
12 mm to 125 mm — widest bore range in the GBC locking nut housing programme.
Insert Replaceable
Locking nut allows insert replacement without housing replacement — lower lifecycle cost.

🔭 Materials & Construction
Housing body: structural steel, machined, long-body design. Locking slot nut: steel. Insert: GE..LO extended-length radial spherical plain bearing — 100Cr6, phosphate-treated, lubrication grooves.
Long Steel Housing
Extended body. Slot nut bore and locking screw. Machined structural steel.
GE..LO Long Insert
Extended contact length for higher moment load capacity.
Locking Slot Nut
Positive outer ring retention in extended housing bore.
🏭 Typical Applications
Heavy Crane and Hoist
Long-design pivot housings for crane hook block connections and hoist drum end pivot frames.
Offshore Riser Systems
Extended-length housings for riser tensioner pivot connections and subsea equipment handling frames.
Heavy Press Frames
Long bearing span pivot housings for eccentric drive and toggle press pivots under high moment loads.
Steel Mill Rolling Stands
Long-design housing for mill roll chock pivot connections and side guide arm pivots.
Ship Propulsion Equipment
Long pivot housing for stabiliser fin actuator connections and azimuth thruster support pivots.
Heavy-Duty Automation
Long bearing span rod end housings for large industrial robot base pivots and heavy transfer mechanism arms.

🔧 Installation & Maintenance
🔎 Insert Seating
GE..LO insert must be fully seated to housing shoulder before tightening locking nut.
🔧 Locking Nut Torque
Tighten slot nut with hook spanner to specified torque. Engage locking screw fully.
📈 Alignment
Long bearing span requires careful shaft alignment — misalignment loads are amplified by the longer moment arm.
⚙ Lubrication Before Use
Apply NLGI-2 EP grease through nipple before first use.
🌡 Temperature
-30 to +110 C with mineral EP grease and standard GE..LO insert.
✅ Insert Replacement
Remove locking nut and press out worn GE..LO insert. Re-install new insert.
