Description
DBH 5053Sil belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 5053Sil and any equivalents.
A radial shaft seal from the DBH line, the 5053Sil keeps oil and grease where they belong while blocking dust and water from reaching the bearing cavity. Its dimensions are 25 mm at the shaft, 40 mm at the housing and 8 mm in height. Gearboxes, pumps, motors and other power transmission equipment are the usual homes for this size. MR Industrial Accessories supplies this brand and can help you match the seal to your lubricant, shaft speed and surface finish.
The 5053Sil carries the Lx designation, which means a single lip with a spring. The elastomeric lip rides against the shaft, and the spring holds steady contact pressure against it, while the outer body stays press-fitted in the bore. Shaft diameter is 25 mm, housing diameter 40 mm and height 8.00 mm. Because it is a wear part, it gets replaced once lubricant starts escaping or contaminants find their way in.
You will find a seal this size on gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt or chain driven equipment, as well as machine tools, washing equipment and irrigation systems. Any time a rotating shaft passes through a housing with lubricant behind it, a seal of this type holds the oil in and keeps outside dust out.
Before installing, confirm the shaft is clean and free of burrs or marks, with suitable hardness and roughness, and that the bore has the right diameter and chamfer. Lubricate the lip, then drive the seal in with a tube that presses on the outer edge rather than the lip. For high speed, elevated pressure or extreme temperature service, contact us and we will review whether a different material or geometry fits better.
When you ask for a quote, include the code 5053Sil along with the shaft and housing diameters. That is enough for us to search the DBH line or a compatible alternative. If space permits, the same seal can also be supplied in another height or with a different design. The more detail you share about the equipment, the faster we can give you a useful answer.

Frequently asked questions
- What are the dimensions of the DBH 5053Sil oil seal?
- Shaft 25 mm, housing 40 mm and height 8.00 mm, in the Lx design with a single lip and spring. Compare those three figures against your equipment before ordering.
- How can I tell whether this seal replaces the one on my machine?
- Use a caliper on the old seal: shaft, housing and height. If you read 25, 40 and 8 mm and the design is similar, it drops in. If any figure differs, send us the measurements and we will look for the correct variant.
- What should I watch for during installation?
- Keep the shaft clean and free of burrs, with the proper finish. Lubricate the lip, press on the outer edge with a suitable tube and keep the seal straight so the lip is not damaged.
