🆕 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.

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

🔧 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.

❓ Frequently Asked Questions

▶ What bearing insert does the GK/GF/GIHR/GIHN housing use?

GK..DO, GF..DO, GIHR..DO, and GIHN-K..LO housings incorporate a radial spherical plain bearing (GE..ES or GE..ES 2RS) as the insert element. The housing provides the structural mounting interface while the spherical plain bearing provides the self-aligning sliding contact.

▶ What does the DO suffix mean?

DO indicates a weldable or weld-base housing design. The housing body has a weldable base plate or weld preparation that allows direct welding to a structural frame or clevis bracket, eliminating fastener holes and reducing installation complexity for heavy structural applications.

▶ Can GK/GF housings be sealed?

Yes. GK..DO and GF..DO housings can be manufactured with 2RS lip seals. Sealed designs are recommended for contaminated or outdoor environments. The standard open design is used where contamination risk is low and re-lubrication access is easy.

▶ What is the re-lubrication method for these housings?

A lubrication hole and grease nipple are provided on the housing body. Apply NLGI-2 EP grease through the nipple at regular intervals depending on load and contamination level. Asterisk sizes indicate re-lubrication is not possible for that size.

▶ How is the GIHN-K..LO series different from GIHR..DO?

GIHN-K..LO is the long design (LO) locking-nut housing. It has an extended body length that increases the moment load capacity significantly compared to GIHR..DO for the same bore. It uses the GE..LO long spherical plain bearing insert.
