The DBH 5270Sil is a single-lip radial shaft seal with a spring, built for rotating shafts. It keeps lubricant in and contaminants out, protecting bearings and mechanisms. With a 30 mm shaft, 40 mm housing and 7 mm height, and an Lz design, it handles tough industrial conditions.
The part number 5270Sil tells you the main dimensions: 30 mm shaft (d), 40 mm housing (D) and 7 mm height (h). The Lz designation means the sealing lip has a spring that maintains steady contact on the shaft. The seal uses a high-resistance elastomer and a metal case for a firm fit in the housing.
You will find this oil seal in gearboxes, pumps, electric motors, reducers and power transmission equipment. In food, chemical or process plants where washdowns and external agents are common, it prevents lubricant loss and helps bearings last. It also suits agricultural and road machinery where dust and dirt are constant concerns.
When installing, clean the shaft and housing and remove any burrs or scratches. Lubricate the lip with the same oil or grease used in the equipment. Press the seal in perpendicularly, applying force on the metal case, not the lip. Confirm the spring faces the lubricant side. If the shaft is worn, look into a seal with an auxiliary lip or a repair sleeve.
Need a cross-reference? Send the original part number, exact dimensions or a photo via WhatsApp or email. We can suggest equivalents with the same shaft diameter but a different housing or height, or with another lip design. Our team responds quickly and helps you choose the right seal.

Frequently asked questions
- What does the Lz design mean on this oil seal?
- The Lz design indicates a sealing lip with a spring, which maintains constant contact on the shaft and compensates for small misalignments or wear.
- Can I install an oil seal with different dimensions?
- It is not advisable to use an oil seal with dimensions other than the original, as it may not seal properly. If you cannot find the exact size, contact us and we will look for a suitable alternative.
- What should I watch for during installation?
- Clean the shaft and housing, lubricate the lip, and install the seal perpendicularly. Avoid hitting the lip and make sure the spring is on the lubricant side.
