Thanks for that mercury, nicely explained it's an interesting concept with the ball bearings and have never heard of it before, cheers,

Yes is it 1001DA for six pins The first time was thinking as five pins by using five pins key blank but found out the first one was a no cut "0" with five cut 9-0-9-0-9. Need to feel your pins by using the pick tool to be sure using six pins key blank.

They do have them in Corbin cylinder lock, Russwin lock also have it. Don't know of any other lock manufactured use it ..Timothy.....

Thanks Timothy, can't recall seeing them over here or mention of the ball bearings combined between the pins before, it's an interesting one, cheers.

From Corbin Russwin Cylinder/Keying Parts & Service Manual, earlier versions originally edited by the late Anthony "A.J." Hoffman, pg. 55:
You will find a ball bearing at the bottom of pin stacks in some or all chambers of Corbin and Russwin cylinders manufactured from about 1902 until the mid 1960s. The oldest cylinders have a ball in every chamber. The number of balls was gradually reduced until only the front two chambers had them. The purpose of the balls was to reduce wear on the pins. As harder brass became available, wear became less of a factor, so usage of the balls was eventually phased out.

In my personal experience, I have found that after heavy usage over a period of many years; that the balls often developed a "flat" at the point where they met the top pin. This slight amount of wear could make the key more difficult to turn since the pin was then a tad below the shear line due to the slightly reduced diameter of the ball.

This is the Corbin Cabinet Lock (now CCL Security Products) "BR" keyway, not to be confused with the similarly lettered "BR" keyway (Ilco 1001GB) used by its former sister company P & F Corbin (now Corbin Russwin). The three iterations of the CCL "BR" section were:

• 4-pin 4192C-BR (1001DB Old Ilco)
• 5-pin 4193C-BR (1001D Ilco)
• 6-pin S4195C-BR (1001DA Ilco)

Only the 5-pin blank is still available in an OEM version from CCL Security Products.

Some mogul cylinders for prison locks also use them.

Here Picture of the Corbin Padlock with ball bearig. I also took picture of Russwin pins. Yes this as five ball bearing....Timothy.....

Here another information only the size of ball bearing: 1902-1960's .116" ballbearings were inserted to reduce wear until harder brass was available for keyblanks. All five chambers of Corbin and Russwin used to contain ball bearingsuntil 'lock combing' became an issue. Ball bearings wear gradually reduceduntil only the first two chambers contained them. The older the lock, the morethe bearings....Timothy......

Gents, this is interesting stuff indeed, the use of the term 'ball bearings' has got me extremely curious.
Were they actually ball bearings, as in extremely hard, case-hardened balls intended for bearing races, or were they just steel balls made for the purpose? A simple 'file test' would obviously be a very quick way to reveal what's what.

[Timothy]

Good question that what I try to find out. I have no answer of what they call for the lock but I'm sure everyone know it ball bearing or steel ball, Just maybe someone may come up with answer...Timothy....
