When a shaft spins inside a housing, the DBH 5133 oil seal keeps lubricant where it belongs and keeps dust and water out. This radial shaft seal has a single lip with a spring and is sized for a 20 mm shaft, a 30 mm bore and a 7.00 mm height. MR Industrial Accessories supplies this brand and helps you match the right seal to your equipment.
The designation 5133 identifies a DBH radial shaft seal. Its dimensions are shaft (d) 20 mm, housing (D) 30 mm and height (h) 7.00 mm. The Lz design means a sealing lip with a spring, made for rotating shafts. MR Industrial Accessories carries the DBH brand, so you can request this reference or ask about equivalent options we supply.
You will find seals like this wherever a shaft turns inside a housing and lubricant must stay in while contaminants stay out. Common locations include gearboxes, centrifugal pumps, electric motors, reducers, mixers and machine tools, as well as rollers and transmission shafts working in dirty conditions.
Before installing, confirm the shaft measures 20 mm and the bore measures 30 mm, with enough housing width for the 7.00 mm height. The shaft surface should be ground and free of burrs, and the lip should be lubricated before you slide the seal into place. If your equipment runs at high speed or under heavy pressure, ask us about reinforced versions or alternative materials. Speed, temperature and the type of lubricant all affect the choice.
If your shaft or bore is different — say a 19.05 mm shaft or a 32 mm housing — we can search for a cross-reference among the brands we carry. Just send the shaft diameter, the housing diameter and the height, or the original part code. We can also quote the same seal in another material when your application calls for it.
To order the DBH 5133 oil seal or ask about a replacement, message us on WhatsApp or by email with the code. Our team replies promptly with a quote and alternatives, and can help you confirm the right seal for your equipment.
