🆕 Series Overview

The GK..DO series is a rod end housing with a weldable base plate and dowel pin location for direct welding to a structural frame or bracket. The housing incorporates a radial spherical plain bearing (GE..ES or GE..ES 2RS) and a female thread on the housing body for connection to a male-threaded rod or actuator.

Available in 14 bore sizes from 10 mm to 80 mm. Sealed design (2RS) available — e.g., GK 50DO 2RS. Lubrication hole and nipple provided. Sizes marked with asterisk cannot be re-lubricated. Dowel pin hole provides precise positioning before welding.

🔧 Installation & Maintenance

🔎 Pre-Weld Positioning

Use dowel pin for accurate positioning. Tack-weld before final welding to verify alignment.

🔧 Weld Procedure

Use compatible electrode. Do not weld within 50 mm of the bearing insert — heat damages the bearing.

📈 Insert Protection

Remove or shield insert with heat-resistant material before welding.

⚙ Post-Weld Lubrication

Apply NLGI-2 EP grease through nipple after welding and before commissioning.

🌡 Temperature

-30 to +110 C with standard GE..ES insert, mineral EP grease, and NBR seals.

✅ Re-lubrication Interval

Every 200–500 hours. Asterisk sizes cannot be re-lubricated — replace when worn.

❓ 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.
