The DBH 5310Sil is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 20 mm shaft, a 42 mm housing and has a 7.00 mm overall height. The Lz profile features a single lip with a spring, making it suitable for oil or grease retention in gearboxes, pumps, motors and similar power transmission assemblies where space is tight.
This seal is identified by the code 5310Sil from the DBH line. The dimensions are shaft 20 mm, housing 42 mm and height 7.00 mm. The Lz designation indicates a single-lip, spring-loaded profile for rotating shafts. DBH is one of the sealing brands MR supplies, so you can check the part number directly against your equipment’s documentation.
Radial shaft seals of this size are common in gear reducers, centrifugal pumps, electric motors and conveyor, fan or mixer shafts. Their job is to retain oil or grease and block dust, water or particles from reaching the bearings. As a wear component, the seal should be replaced when leakage appears or when the lip feels stiff or shows damage.
When selecting a replacement, confirm the shaft diameter, housing bore and width match the original. The shaft surface must be clean, free of burrs and deep scratches, and the housing chamfer should be intact. Lubricate the lip with the same lubricant used in the equipment before installation and press it in evenly without impact. Misalignment or a damaged lip will reduce seal life.
For an equivalent, send the part number 5310Sil or the three dimensions by WhatsApp or email. The team can locate the corresponding DBH reference or suggest an alternative with the same shaft, housing and height. Providing the lubricant type, operating temperature and shaft speed helps narrow the choice within the radial shaft seal range.
