The DBH 5267 is a radial shaft seal built for rotating shafts where lubricant retention and contaminant exclusion are required. It measures 20.00 mm at the shaft, 40.00 mm at the housing and 4.00 mm in height, and its Lt design uses a single lip with spring. You will find this seal in gearboxes, pumps, electric motors and power transmission equipment, where it keeps oil or grease in and dust, water or particles out.

This seal carries the DBH designation 5267 and the Lt configuration: one lip with a spring, intended for lubricated rotating shafts. The elastomer lip runs against the shaft while the metal case presses into the housing bore. As a wear part, it is replaced when leakage or dirt ingress shows up during maintenance.

Reading the size is straightforward. Shaft diameter is 20.00 mm, housing diameter is 40.00 mm and height is 4.00 mm. Those three values are what you confirm before ordering, since the housing bore and shaft condition determine whether the seal seats correctly.

Typical uses for this size include small gearboxes, centrifugal pumps, electric motors, reducers, fan shafts, mixer shafts and conveyor shafts. In every case the job is the same: hold the lubricant inside the bearing or gear area and block outside contamination.

During installation, verify the shaft is within tolerance and free of burrs or marks. Lubricate the lip before sliding it on, and press on the metal edge with a support tube rather than on the elastomer. The seal should sit perpendicular to the shaft. When selecting a replacement, consider rotation speed, working temperature and the fluid involved. A worn shaft may call for a repair sleeve or a different size.

For a quote, send the part number 5267 or the dimensions 20x40x4 mm by WhatsApp or email. The team can suggest equivalents in other brands or with different heights and diameters, always checking the manufacturer's data sheet first. If your original seal carries another designation, or the housing accepts variants, that can be reviewed as well.
