When a gearbox, pump or motor starts weeping oil around the shaft, the first thing to check is usually the radial shaft seal. The DBH 5151Sil is a lip seal with a 38 mm shaft bore, a 52 mm housing bore and an 8 mm height, built in the Lx design. MR Industrial Accessories supplies this brand and can help you match the seal to the assembly before you order.
Reading the code is straightforward once you know the layout. The 5151Sil number identifies the item within the DBH oil seal line, and the dimensions follow the usual order: d for the shaft, D for the housing bore, h for the height. Here that means 38.00 mm, 52.00 mm and 8.00 mm. The Lx designation describes how the lip and the metal case are put together, following the manufacturer's own naming system.
In service, the seal is pressed into the housing with the lip turned toward the lubricant. It is a single-lip type intended for rotating shafts that run with permanent lubrication, so its job is to hold oil or grease in place and keep dust, water and particles out. That protection matters most for the bearings and gears sitting behind it.
You will run into this size in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment, and also as a secondary closure where splashing or a dusty environment is present.
Selection is not only about the three numbers. Check that the shaft and housing bores match the values above, that the 8 mm height fits the housing depth, and that the lip will run on a surface free of grooves or burrs. A worn shaft may call for a wear sleeve. Speed, temperature and the lubricant in use also affect the lip material, so dimensions alone do not settle the choice.
For a quote on the 5151Sil, send the shaft, housing and height dimensions, and a photo of the old seal if you have one. We can look for the same size in another brand or for an alternative within the DBH line, and we can tell you whether a different lip or case type is needed instead of the Lx.

Frequently asked questions
- What size is the DBH 5151Sil oil seal?
- It fits a 38.00 mm shaft and a 52.00 mm housing bore, with a height of 8.00 mm. The design is Lx. Compare these three values with your assembly before requesting a quote.
- How can I tell whether the Lx design suits my equipment?
- The Lx code describes the lip and case configuration. Put the old seal next to the product data, or send us a photo with the dimensions on WhatsApp. If the lip or case does not match, we look for another variant in the same line.
- Can you source an equivalent from a different brand?
- Yes. Send the code 5151Sil along with the shaft, housing and height dimensions. With that information we search for an equivalent seal in another brand or an alternative within the DBH line, keeping the dimensions and design type your equipment requires.
