When a rotating shaft needs to hold lubricant in and keep dust and water out, the DBH 5492 oil seal is the part that does that job. It is a single-lip radial seal that presses into a fixed housing and rides against the shaft. The size falls in the medium range, which makes it a common replacement item in pumps, motors and gear drives. MR Industrial Accessories supplies this seal and quotes it from the part number.
The three values that define this seal are shaft 43.80 mm, housing 69.30 mm and width 12.70 mm. The Lz design means a sealing lip with a spring and an outer metal case, built for shafts that turn under permanent lubrication. The number 5492 pins down one exact size in the DBH line, so it pays to measure the old seal in all three directions before ordering a replacement.
Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, compressors and other power transmission equipment, as well as in agricultural machinery and process lines. In every case the seal sits between a moving shaft and a stationary housing, holding oil or grease in place while blocking contaminants that would otherwise shorten bearing and gear life.
Before pressing a new seal in, check the shaft for burrs, nicks or deep wear marks and make sure the housing bore is clean and round. Coat the lip with the same lubricant used in the unit, then seat the seal square so the spring is not disturbed. A grooved shaft may call for a repair sleeve. Speed, temperature and lubricant type all affect seal selection, so those details are worth confirming.
To get a quote on code 5492, send the shaft, housing and width measurements, plus a photo of the old seal if you have one. From there we can look at other options in the DBH line or in the other brands we carry, and we can help if the housing is damaged or the shaft measures differently from the original.

Frequently asked questions
- What size is the DBH 5492 oil seal?
- It fits a 43.80 mm shaft in a 69.30 mm housing and is 12.70 mm wide. All three measurements need to match the equipment so the seal seats correctly and does not leak.
- What does the Lz design indicate?
- Lz identifies a radial shaft seal with a spring-loaded lip and an outer metal case, made for rotating shafts with permanent lubrication. If the lip orientation is unclear, ask us before installing.
- How can I find an equivalent seal?
- Send code 5492 along with the shaft, housing and width dimensions of the seal you are replacing. We will check alternatives in the DBH line and in other brands we supply, then quote them.
