Clock Pendulums

The clock pendulums on this page are for post 1960 mechanical German clock movements only. To get the proper clock pendulums for your clocks, you would need the movement numbers off of the back plate of the movement itself. Not off of the paperwork, not off of the wood case, but off of the clock engine itself. Then with this information we can determine what the CM length of your clock is and the manufacturer of it. There is in fact a few things we need, who the manufacturer is, the CM length, how wide the inside of the clock case is so we can get the right bob size. The manufacturer for German movements will most likely be one of the four listed below. The CM length is stamped on the back plate and represents the length of the pendulum from tip to tip, the leader it hangs on, and the suspension spring that the leader hangs on, all added together in centimeter measurement. Then to figure out the bob diameter, this is the round disk at the bottom of the pendulum and it needs about 2 inches on each side to swing around in the case without bonking the sides of the clock case.

Clock Pendulums

German Seth Thomas and Mason Sullivan did not make their own movements or clock pendulums. You would need to follow the link and find out the true manufacturer. CM lengths on German movements are the clock pendulums length from the suspension post all the way down to the bottom of the pendulum. This includes the suspension spring, the leader that hangs on it and the pendulum itself from tip to tip. This means the actual clock pendulums length itself will be much shorter than this measurement.. Below are just a few examples of actual numbers that exist so you can see the pattern and determine who made your clock movement.

Clock PendulumsClock Pendulums

We offer the above clock pendulums bobs with various patterns. These are for mantle movements with the F-S regulator that you can adjust the timing.

Clock Pendulums #PD10


Adjustable Bob

Clock PendulumsClock Pendulums

This pendulum bob is threaded on the bottom with a rating nut for easy timing of the clock. This can be used on mantle clocks as well as certain wall clocks such as a banjo. Measurement is the diameter of the bob.

Clock Pendulums #PD5


Grape Leaf

Clock PendulumsClock Pendulums

Gold tone brass pendulum with leaf decorations on the top of the pendulum bob. This pendulum measures seven inches in length and has a 2 1/2 inch diameter bob that weighs 3.5 ounces. Used with some modern wall clocks and 31 day clocks.

Clock Pendulums #PD28


Adjustable Pendulum

Clock PendulumsClock Pendulums

Bob is 35mm in diameter and weighs two ounces.

Clock Pendulums #PD22


Adjustable Mantle Bob

Clock PendulumsClock Pendulums

This is a 1 5/8 diameter 2.8oz adjustable mantle clock pendulum bob. This is the bob needed if there is no F / S regulator on the front of the clock dial that takes the skinny end of the key. This can be used in place of a F / S regulator as well if finding the right key is not easy. This is on a slider to regulate the time, up with the bob is faster time and opposite for slow.

Clock Pendulums #PD20


R + A Style

Clock PendulumsClock Pendulums

R and A style clock pendulum with a hook top and the rating assembly on the bottom to regulate the time.

Universal Pendulum

Clock PendulumClock Pendulum Parts

This pendulum can be used for many clocks. The clock pendulum parts rating nut can be removed completely if needed and it can just be adjusted shorter with the set screw on the back. Just cut the rod shorter to what is needed.

Item #PD18

To get the CM length manually, measure from the top of the movement all the way down to the bottom of the pendulum rating nut threads. This measurement will include the suspension spring, the leader, and the pendulum tip to tip.

One Inch = 2.54 CM

The below chart is to get the approximate pendulum length tip to tip when its off of the clock, this is the pendulum only no leader or suspension. The smaller the bob, the shorter the pendulum will be.
