Hinges for Heavy Doors: What Carries 100kg, 150kg and 200kg

Updated 2026-11-08 · RAYEN 雷茵

What should you measure?

• Door weight in kg, with cladding, glass and hardware. Weigh one door if you can.
• Height and width.
• Thickness at the hinge edge.
• How often it opens, and whether a closer pulls on it.
• Frame material, because it has to carry the hinge screws.

Which hinges carry a printed load?

Three kinds do, and each counts the hinges differently. Read the count before you compare figures.

• Concealed hinges are rated on two hinges. R-CC200 carries 200kg on a pair, not on each.
• The RY8001–RY8004 hydraulic hinges are rated per set. RY8001 carries 60kg on two hydraulic, 80kg on two hydraulic and one plain leaf, and 90kg on three hydraulic.
• The EDA hydraulic hinges are rated on three: EDA-20 carries 80kg on three hinges.

Concealed hinges: 100kg and up

At 100kg you can choose R-CS100, RY100 or RY150. At 120kg you can choose R-CC120J, R-CF120, RY120, RY140 or RY177. At 200kg the door must be thick: 45mm for R-CC200, 48mm for R-CC200J and 62mm for R-CC300. All of these stop at a door width of 1000mm. The EDA series reaches 200kg with EDA-40, 240mm long in 304 stainless, with no minimum door thickness printed.

Where is the number of hinges stated?

Only on RY8005 and RY8006 is the count tied to door size. Both read the same:

• One plain barrel and one hydraulic: door up to 2000mm high and 800mm wide.
• Two hydraulic: up to 2200mm high and 900mm wide.
• Three hydraulic: up to 2400mm high and 1200mm wide.

RY8006 carries 75kg on two and 100kg on three. RY8005 carries 55kg on two and 75kg on three. For other hinges no count is printed. Do not add a share per hinge yourself. Send us the door, and we confirm it.

What about ball bearing hinges?

No load is printed for them. What the range does show is how the hinges grow: a bigger leaf, a thicker leaf, a larger knuckle and more bearings.

Sorted by knuckle, the largest hinges gather at the end. 6x4x3.5-4BB is 152.4 × 101.6mm, 3.5mm, Ø16.2mm with four bearings. 8x4x3.5-6BB is 203.2 × 101.6mm, 3.5mm, Ø16.2mm with six. 4.5x4.5x3.5-2BB US pairs a 3.5mm leaf with a Ø15.2mm knuckle. On a heavy door, start from these and from four bearings or more. The ball bearing guide explains why the bearing count alone is not a rating.

When should you stop using hinges?

Past 200kg, or past 1000mm wide on a concealed hinge, look at floor springs. They carry the door from below. RAYEN's run from 50kg to 600kg, and some reach ≤1500mm from spindle to edge. See the floor spring size chart.

A worked example

A meeting-room door is 50mm timber, 150kg, 2400mm high and 1000mm wide, and it must hide its hinges. R-CC200 fits: 200kg on two hinges, a door of 45mm or more, and 1000mm wide. R-CC200J fits too, at 48mm. R-CC300 needs 62mm, so it does not fit. No height is printed for these hinges. At 2400mm, send us the door so we confirm whether a third hinge is needed, and where it goes.

If the same door should close by itself, it is beyond the hydraulic hinges. RY8006 stops at 100kg. A floor spring such as D-5063.150, rated 150kg at ≤1200mm, is the route to look at.

What should you write on the order?

• Model, and hinges per door.
• Door weight, height, width and thickness.
• Frame material.
• Material grade and finish.
• For hydraulic models, the set: how many hydraulic and how many plain.
