The DBH 5317Sil is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a fixed housing. Its Lx design uses a single lip with a spring, and it measures 30.00 mm at the shaft, 42.00 mm at the housing and 8.00 mm in height. MR Industrial Accessories includes it in its line of seals and oil seals for maintenance and repair work.

You will find this seal identified by the code 5317Sil under the DBH brand. The three dimensions to match against your equipment are shaft diameter (d) 30.00 mm, housing bore (D) 42.00 mm and height (h) 8.00 mm. In the Lx design, a spring-loaded single lip runs against the rotating shaft while the metal outer case presses into the housing bore. Because the lip is a wear part, it is normally replaced once leakage or contamination shows up.

Typical service includes gearboxes, reducers, centrifugal pumps, electric motors, compressors and other power transmission equipment. In each case the seal holds oil or grease inside the assembly and blocks dust, water and particles that would otherwise shorten bearing and gear life. Machine tools and process equipment with a rotating shaft in a fixed housing also use this type of seal.

Before ordering, confirm that the shaft and housing dimensions match the equipment. The Lx designation tells you the lip style and how it should face. Put a little of the same oil or grease on the lip during installation, keep the seal square to the shaft, and avoid impacts that could deform it. A nicked lip or a scored shaft will leak early; if the shaft is worn, a repair sleeve or a seal with the lip in a different position may be the better route.

If you need an equivalent to the 5317Sil, send the complete code, the shaft, housing and height measurements, and a photo or sample of the old seal. With that information we can search for an alternative in the DBH line or in other brands we carry. We can also tell you whether the Lx design fits your application or whether another lip type or material should be considered.
