The DBH 5445Sil is a radial shaft seal built to keep oil and grease where they belong while keeping dust and water out of rotating assemblies. Its Lx configuration is a single lip with spring, oriented to hold lubricant on one side and block contaminants on the other. The seal presses into crankcases, covers and gearboxes. MR Industrial Accessories supplies this brand and can help you confirm the reference fits your equipment.

Reading the code is straightforward. The DBH 5445Sil carries a commercial designation, and the three figures that follow describe the bore it seals: shaft 17.50 mm, housing 28.50 mm, width 7.00 mm. The Lx suffix tells you the lip style, which is a spring-loaded single lip. With those numbers on hand you can match the seal against other options from the same brand without guesswork.

Seals in this size range turn up in small electric motors, centrifugal pumps, speed reducers, compressors, machine tools and general power transmission equipment. You will also find them on fan, mixer and conveyor shafts that run continuously in the presence of oil or grease. Because the lip wears against the shaft, it belongs on your preventive maintenance checklist; catching it early avoids lubricant loss and the bearing and gear damage that follows.

Installation matters as much as selection. Inspect the shaft for burrs or wear and make sure the lip contact surface is clean and lightly lubricated. The housing bore should be free of nicks or impact damage. Press the seal in with a tube sized to the outer diameter rather than striking the lip directly. If the application runs hot or with heavy vibration, a different lip compound or profile may suit you better. Shaft speed, lubricant type and working pressure all feed into the final choice.

Looking for a replacement? Send the code 5445Sil or the three dimensions of the seal you are pulling out. We can search the same brand or the other lines we carry, keeping the lip type and design in mind. We will also tell you whether the cavity allows a different height or whether a version with extra dust protection is the smarter move.
