The DBH 5027Sil is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It seats in the housing and rides on the shaft with a flexible lip that absorbs minor misalignment, protecting the bearings and bushings behind it. You will find it in pumps, motors, gearboxes and other power transmission assemblies where dust, water or splashes are present.

The dimensions to check against your equipment are shaft 48.42 mm, housing 81 mm and overall height 11.90 mm. The 5027Sil code identifies the size and construction within the DBH line, while the Lz design tells you the seal carries both a sealing lip and a dust lip: one holds the oil or grease, the other keeps external contaminants off the sealing edge. Confirm shaft and housing tolerances before fitting.

Common installations include centrifugal pumps, electric motors, speed reducers, transmission shafts and process equipment. In each case the seal sits next to a bearing or bushing, retaining lubricant and blocking dirt ingress. Agricultural machinery, material handling equipment and hydraulic systems with continuous shaft rotation are also typical. The compact cross-section suits housings where axial space is limited.

Selection depends on shaft speed, operating temperature and the lubricant in use. The Lz design fits applications with moderate dust or splash exposure. During installation, coat the lip with the same oil or grease used in the machine, press the seal in perpendicular to the shaft and avoid striking the lip. If the shaft surface is worn or rough, replace the shaft or fit a wear sleeve to keep the sealing edge working properly.

If you need an equivalent or a close variant, send part number 5027Sil or the three dimensions of your current seal by WhatsApp or email. The team compares that data against manufacturer product pages and suggests the closest match, including other DBH line seals when your application calls for different temperature or speed characteristics.
