DBH 8415 radial shaft seal — 42 x 58 x 7

DBH 8415 belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 8415 and any equivalents.

The DBH 8415 is a radial shaft seal built around a 42 mm shaft, a 58 mm housing bore and a 7 mm height, supplied in LMz design. Its lip rides against the rotating shaft while the metal case stays fixed in the bore, so lubricant stays inside the assembly and outside contamination stays out. Because the lip wears against the shaft over time, the seal is treated as a replacement item: once oil starts weeping or grit works its way in, it gets swapped out. We supply this seal as a brand and help you confirm the size before you order.

The part carries the designation 8415, and the numbers behind it describe the fit: shaft side 42 mm, housing side 58 mm, overall height 7.00 mm. LMz refers to the lip and case geometry, which in this case is a single-lip layout for a lubricated rotating shaft. Should you need to check tolerances, lip hardness or the elastomer used, we go back to the manufacturer's data sheet and confirm the details before sending a quote.

Seals in this size range show up in gear reducer housings, centrifugal pumps, electric motors, rollers and transmission equipment. The usual setup is a shaft turning inside a stationary bore, with the seal keeping oil or grease contained and blocking dust and water from reaching the bearing cavity. In continuous-process machinery, this is a consumable pulled and replaced during planned shutdowns. Where dirt is heavy or operating temperatures run high, it pays to review the lip profile and the elastomer before committing to a replacement.

Three checks matter when you select and fit a seal like this one: shaft and housing diameters against the part, height against the space available, and lip condition during installation. Lubricate the lip first, drive the seal with a tool that never crosses splines or keyways, and inspect the shaft for burrs or scoring. A shaft with visible wear marks may not let a new lip seat properly, in which case the shaft condition needs attention or another approach has to be considered.

For code 8415, we can search for an equivalent with the same shaft, bore and height figures. The most useful things to send are the original code, a photo of the part and caliper measurements if you have them, plus details on the equipment it came out of. With that on hand, we review options across the DBH line and the other brands we supply, then quote.

If you need the DBH 8415, or want us to hunt down a matching equivalent, send the code over WhatsApp or email and we will get back to you with a quote. We can also walk you through installation or tell you which measurements are worth having ready before you place the order.
