Antique Clock Suspension Spring

Most round antique clock movements use this spring. These clocks were popular prior to 1950 and goes way back from there. It is known as a suspension because it suspends the pendulum in the air.

The second part of the name is spring because it flexes back and forth. It would be a good idea to order a spare spring . One can be put on the bottom of the weight section of the clock for next time the spring breaks. That way you will have a spare and will not be without the use of your clock.

Clock Pendulum Suspension-Spring Information

The following is a discussion on clock pendulum suspension-spring information. Naturally, suspension springs do not have to be exact in length. If the clock runs slow, simply raise the pendulum bob with the rating nut at the bottom.

Likewise, if the clock is running fast then turn the rating nut to lower the pendulum bob.

Most common springs

By and large, suspension spring A is the most common style suspension spring. Of course, it is most likely the one by default.

If the old suspension spring looks similar to this one then it is right. As a general rule of thumb, small mantle clocks take suspension A1, wall clocks and small grandmother units will take suspension A2.

The A3 size is for grandfather clock units with a larger pendulum bob diameter.

This size can also be seen on Grandmother clocks with larger bob diameters. Use the larger A3 with large bob diameters so the bob will not wobble front to back.

If using a pendulum with a bob of 8 1/2 inch diameter or larger please order Suspension A3 for this reason.

Not as common

Urgos uses the single hook style as seen in picture suspension B. However suspension A was the very most common to use.

Very old antique round movements mainly use Suspension C and Suspension D. These are mainly French clocks and US made units made prior to 1945.

I recently ordered an Antique Clock Suspension Spring Type C2 (French 1 1/8″ x 3/16″) from you. I had to cut and seal the bottom of the suspension assembly because the pendulum would not hook over the bottom pins. The modified assembly is working fine.

The dimensions of the suspension spring I replaced are as follows: the distance from the center of the pins where the pendulum hooks over to the bottom of the suspension assembly is 0.085″ or roughly 3/32″. I have 2 questions:

  1. What do the dimensions in the description refer to (1 1/8″ x 3/16″)?
  2. Which suspension spring should I order in the future to avoid having to cut and seal?

Thank you

Hi. I have a Japy Freres with a number 3083 and a 41 below it on the back of the movement, and I need a suspension spring. Would one of yours work?

I have a P. Japy movement that needs a suspension spring. Looks like G7433 on the back of the movement. Any idea which suspension spring I need? thanks

Hello. I’ve a clock that was dropped during a move some time ago and I am only just repairing it. Fortunately, aside from some of the marble being broken, the clock, itself, seems in good shape excepting the broken spring, so I was very excited when spring ‘C’ arrived. It seemed to be the right fit. The mechanism is the same as in the first picture at the attached link. A Silk suspension, I think. HOWEVER!! The pin is graduated in size and prevents the spring from being centred. Can I just switch it out for a thinner pin? Or have I the wrong spring? The clock is marked BB 569 on the rim; Hy. Map. ‘C’ or ‘G’, Paris. 56569. Could be Mar, but I don’t think so.
Thank you.

I need a suspension spring like item ‘D’ shown in your most common suspension spring diagram.

I have a 4 glass French mantle clock with mercury filled pendulum. The suspension spring looks like the one in figure “C”, however it is too long as the pendulum fitted with its finial touches the bottom of the case preventing it from swinging. The suspension spring has nylon parts and is probably not original, what length is the spring in figure “C”?
