Heavy Duty Bearing Gate Hinge suits 40mm Tube - 1 Set

Heavy‑Duty Knock‑In Bearing Hinges — Fits 40mm x 40mm Steel Tube | Up to 300kg, Sealed Bearings

Simple to install and engineered for longevity, this pair of heavy‑duty Knock‑In Bearing Hinges will instantly improve your gate’s movement and extend your gate motor’s service life. Designed to press into 40mm × 40mm steel tubing, these hinges suit gates up to 300kg and 2 metres wide, delivering smooth, low‑friction rotation through 180° for reliable everyday operation.

What are the benefits of our Knock‑In Bearing Hinges? 

• Easy DIY installation — simply knock the insert into both ends of the gate frame for a secure fit.
• Ultra‑smooth gate action — sealed ball bearings eliminate binding and reduce start‑up drag on motors.
• Durable construction — zinc‑plated forged A3 steel hinge body resists corrosion and mechanical wear.
• Motor protection — reduces torque load on gate operators, prolonging motor life and lowering maintenance.
• Heavy‑duty capacity — rated for gates up to 300kgs and approximately 2m long.
• Low maintenance — sealed bearings with dust caps and oil seals keep contaminants out and service intervals long.

Why choose our Knock‑In Bearing Hinges? 
Bearing hinges are a simple, high‑impact upgrade for any swing gate setup. Replacing plain‑bore pivots with sealed bearing inserts removes friction points that cause premature motor wear, noisy operation and uneven gate movement. These knock‑in inserts are ideal for new builds and retrofits where a clean, internal hinge solution is required.

Key specifications 

• Fits: 40mm x 40mm steel tubing (confirm internal bore/wall thickness before ordering)
• Capacity: Up to 300 kg (per pair, installation dependent)
• Material: Zinc‑plated forged A3 steel hinge body
• Bearings: Sealed ball bearings with dust cap and oil seal
• Operation: Smooth 180° rotation; ideal for residential and light commercial gates

Installation tips 

• Check tube internal dimensions and wall thickness for correct press fit.
• Fit one hinge at the top and one at the bottom; align gates before final tightening to avoid bearing preload.
• Use appropriate locking hardware and re‑check torque after initial use.
• For heavy or high‑cycle gates, consider periodic bearing inspection and re‑greasing where applicable.
