The DBH 1273Vit is a single-lip radial shaft seal built to the A 109-R AH pattern. It fits a 95 mm shaft running in a 115 mm housing bore, and its 9.50/14.50 mm height covers both the mounting section and an auxiliary lip. That second lip is what makes this seal useful where grit, dust or washdown water is present, since it keeps the main lip working on a cleaner surface.
Reading the code helps when you are matching a seal to an open machine. The 1273Vit number identifies the size and construction within the DBH line, while A 109-R AH describes the geometry: a radial shaft seal with a primary sealing lip and a secondary exclusion lip, both carried on a metal outer ring. The three figures you need for the bore and shaft are 95 mm, 115 mm and 9.50/14.50 mm.
You will find this seal in gearboxes and speed reducers, centrifugal pumps, electric motors and conveyor rollers, and in power transmission equipment running at moderate peripheral speed under permanent lubrication. In every case it sits between a turning shaft and a stationary housing, holding oil or grease in and keeping dust, water and particles out.
Before pressing one in, confirm the shaft surface is hard enough and finished to suit a seal lip, and that the bore is clean with no burrs or nicks. Put a film of lubricant on the lip, then drive the seal in with a tube that bears on the outer ring only. Never load the lip. The 9.50/14.50 mm height tells you the auxiliary lip is there, and it has to face the dirty side of the assembly. A worn shaft can often be brought back with a repair sleeve.
If you are unsure of the size, send a photo of the old seal along with your shaft and housing measurements. We can cross the 1273Vit code to other options in the DBH line or to other brands we supply, as long as the mounting geometry stays the same, and we can tell you whether a different original design means the cavity needs work.

Frequently asked questions
- What size is the DBH 1273Vit oil seal?
- It takes a 95 mm shaft and a 115 mm housing bore, with a height of 9.50/14.50 mm. The design is A 109-R AH, meaning a main lip plus an auxiliary exclusion lip. Those are the figures given for code 1273Vit.
- How do I check whether it replaces the seal I pulled out?
- Measure the shaft, the bore and the height. If you get 95, 115 and 9.50/14.50 mm, it will fit. A different height usually means a different design. Send the measurements and we will confirm.
- Which direction does the auxiliary lip go in?
- On the A 109-R AH design the auxiliary lip faces the dust or dirt side, and the main lip faces the lubricant. Getting that orientation right is what lets the seal do both jobs.
