A radial shaft seal such as the DBH 6078 keeps oil where it belongs and keeps contaminants out of any assembly with a turning shaft. The unit is pressed into the housing bore, while its flexible lip rides against the shaft and absorbs minor alignment error. Because the lip is a wearing element, it should be swapped out as soon as it stiffens or starts marking the shaft surface, before lubricant loss reaches the bearings and gears behind it.
The three figures that identify this seal are shaft 133.35 mm, housing 155.60 mm and width 14.28 mm, matched to the Lz design, which pairs a sealing lip with a reinforced body for continuous duty. Reading them in order tells you what the part does: the bore diameter of the seal grips the shaft, its outer diameter seats in the housing, and the width has to clear whatever space the housing leaves free.
Typical homes for a seal of this size are gearboxes, pumps, electric motors, rollers and other power transmission assemblies in which a shaft turns inside an oil-filled cavity. The same part shows up on process equipment, conveyors and general plant machinery, where grit and moisture from outside are what actually cut bearing life short. Whatever the machine, the job does not change: retain the lubricant, exclude the contamination.
Selection comes down to matching all three dimensions to the shaft and bore, then confirming that the lip style suits the running speed and the lubricant in use. On installation, coat the lip, keep tools away from the sealing edge, and seat the seal squarely with a press or a suitable tube. Inspect the shaft first; burrs, grooves or a worn contact band will destroy a new seal in a short time.
If you would rather not measure, send the shaft, housing and width figures along with a photo of the removed seal and its bore. From that we can identify a match in the DBH line or elsewhere in our range, and confirm whether the Lz configuration suits the application.
DBH is one of the brands MR Industrial Accessories supplies. To ask about an alternative, send part number 6078 or the dimensions by WhatsApp or email and our team will come back with the option that fits your equipment.

Frequently asked questions
- What are the dimensions of the DBH 6078 oil seal?
- Shaft 133.35 mm, housing 155.60 mm, width 14.28 mm, Lz design. Compare all three against your shaft and bore before fitting; a mismatch on any one of them means the seal either will not seat or will not seal.
- How do I request an equivalent if I cannot find part number 6078?
- Send the shaft, housing and width dimensions on WhatsApp, together with a photo of the old seal. With that information we look for a match in DBH or in another brand we carry and confirm the option.
- How often should a radial shaft seal be replaced?
- There is no fixed interval; speed, temperature and contamination all affect service life. Replace it when leakage appears, when the lip feels hard, or when the shaft shows wear at the contact area. Inspecting at each scheduled shutdown avoids larger damage.
