When a shaft seal starts weeping oil or letting grit past the lip, the replacement has to match the bore and the journal exactly. The DBH 5433 is a radial shaft seal built for that job, sized at 12.70 mm on the shaft, 25.37 mm in the housing and 9.52 mm in height. Those compact dimensions suit small pumps, motors and gear units where there is little room to work with.
Reading the number is straightforward: DBH identifies the seal line and 5433 is the size reference for this particular bore and journal combination. The three figures to confirm before ordering are the shaft diameter of 12.70 mm, the housing diameter of 25.37 mm and the 9.52 mm height. The Lz designation describes a single lip with a spring, which is intended for shafts turning in one direction only. Lip and case materials are checked against the manufacturer's data sheet.
You will find this seal in water and oil pumps, small electric motors, gearboxes and gear cases, transmission shafts and handling equipment. Its role is to hold lubricant inside the assembly and keep dust, water and particles out, which protects the bearings and bushings around it. That makes it a routine item on preventive maintenance schedules and repair work.
Fitting goes better when the shaft surface is hard enough and smooth enough, and when the housing is clean with no burrs left behind. Put a film of lubricant on the lip before pressing it in, and keep the spring facing the fluid you want to hold back. A worn shaft may call for a seal with an auxiliary lip or a wear sleeve instead. Speed, temperature and lubricant type all belong in the selection.
