The DBH 8399Pol is a radial shaft seal sized for a 38 mm shaft, a 50 mm housing bore and a 6 mm width. It keeps lubricant where it belongs and keeps dust, water and other contaminants out of the assembly. The Lx-R design uses a spring-loaded lip and a metal outer case bonded to the elastomeric element, which makes it a practical choice where axial space is tight.
Reading the size callout is straightforward: shaft 38 mm, housing 50 mm, width 6.00 mm. The Lx-R configuration refers to the sealing lip with a spring and the combination of a metallic outer body with the elastomeric sealing element. This is a radial-section seal, so it is intended for rotating shafts that run with internal lubrication.
Typical installations include gearboxes, pumps, electric motors, rollers and other transmission equipment where oil or grease has to stay contained. You will also find this size used as a closure on split plummer block housings and in assemblies built around bearings. It suits moderate-speed operation and shafts that do not show significant runout.
When selecting a replacement, confirm that the shaft diameter falls within the tolerance recommended for radial shaft seals and that the contact surface is ground and free of marks. The housing needs the correct diameter and depth so the seal seats without deforming. If the shaft is worn, a repair sleeve is worth considering. Coating the lip with lubricant before installation helps avoid damage at start-up.
If you need an equivalent or a different size, send the part number 8399Pol or the shaft, housing and width dimensions. We can also source a seal with the same Lx-R design in another brand or with a different elastomer when the working environment calls for it, and we can help you choose based on the application.
