The DBH 1025 is a radial shaft seal from the DBH line, built in the Mx configuration: one lip with a spring, meant for rotating shafts that run with lubrication. Its three working dimensions are shaft 42.98 mm, housing 54.10 mm and width 7.49 mm, a combination that fits equipment where axial room is tight. MR Industrial Accessories supplies this brand to plants and workshops throughout the United States and Latin America. Send the part number by WhatsApp or email and the team will come back with a quote.

Reading the size callout is the fastest way to confirm a match. The first value, 42.98 mm, is the shaft diameter the lip rides on. The second, 54.10 mm, is the bore in the housing that holds the outer case. The third, 7.49 mm, is the overall width, which sets how much axial space the seal occupies. Check all three with a caliper before ordering, since a worn shaft can measure slightly under nominal.

Seals in this family show up in gearboxes, pumps, electric motors, drive shafts and general process equipment. They do two jobs at once: they keep oil or grease inside the housing, and they keep dust, water and particles out. In food plants, chemical operations and water treatment, that barrier is often what decides how long a bearing or gear set lasts between service intervals.

Installation is straightforward when the bore and shaft are prepared. Lubricate the lip before sliding the seal into place, and inspect the shaft for burrs, scratches or a visible wear groove that could cut the lip. The 7.49 mm width is the axial limit, so seat the part against its shoulder rather than forcing it into a deeper pocket. If the application runs at high shaft speed or elevated temperature, share those details and the team can review whether the standard Mx configuration is the right choice.

When the old seal carries no readable marking, the measurements are enough to work from. Send the shaft diameter, housing diameter and width, along with the equipment type and the service conditions. From there the team can identify a match in the same brand or suggest an equivalent from another line carried, and can help sort out a replacement when the original identification is missing.

To move forward, send the DBH 1025 part number by WhatsApp or email. A photo of the removed seal or the caliper readings helps confirm the selection. The response includes the option that fits the equipment, and the team can also point you to the right alternative if the exact configuration is not what the application needs.
