A radial shaft seal like the DBH 5233 keeps lubricant where it belongs and keeps dust, water and particles out. It sits between a turning shaft and a stationary housing, which makes it a common sight in gearboxes, pumps, motors and power transmission assemblies. The size callout is straightforward: 75 mm at the shaft, 100 mm at the housing bore and 12 mm of height.
The 5233 follows the Lz pattern, meaning a metal case with a spring-loaded single lip. The three figures that matter when you read the designation are shaft 75 mm, housing 100 mm and height 12.00 mm. The elastomer holds up against mineral oils and the temperatures you would normally see in rotating equipment, which is why this style of seal is so widely used.
Where you will find it: gearboxes, centrifugal pumps, electric motors, conveyor rollers, and belt or chain drives. In each of those spots it does two jobs at once, holding oil or grease in and keeping contamination away from bearings and bushings. Treat it as a wear item. Check it during every preventive maintenance round and swap it out once you see weeping or hear unusual noise around the seal.
Before pressing in a new 5233, confirm the shaft matches the stated dimension and that the surface is free of burrs or deep scratches. A suitable roughness helps the lip last. Put a film of lubricant on the lip, then drive the seal in with a tube or press that contacts the outer diameter only, never the elastomer. The bore itself needs to be clean and undistorted. If the equipment runs with heavy vibration or elevated temperature, ask about compound or design options built for those conditions.
Looking for an equivalent to the DBH 5233? Send the complete part number, the shaft, housing and height measurements, and a photo of the old seal if you have one. That is enough for us to search within the same brand or across the other brands we supply. We can also tell you whether the mounting space accepts a different height or whether the lip style should change based on the lubricant in use.

Frequently asked questions
- What are the dimensions of the DBH 5233 oil seal?
- Shaft 75 mm, housing 100 mm, height 12.00 mm. The Lz design uses a sealing lip with a spring. Always confirm these figures against the housing before installation.
- How do I know if this oil seal replaces the one I have installed?
- Match the three dimensions: shaft diameter, housing diameter and height. If they line up and the lip design suits your lubricant and operating speed, it drops in directly. If something differs, ask us about a nearby size or an alternative from another brand we carry.
- What care should I take when installing a radial shaft seal?
- Clean the housing and inspect the shaft for burrs or marks. Lubricate the lip, then use a tube that presses on the outer diameter, never on the elastomer. Avoid impacts and make sure the seal seats square. Careful installation extends service life.
