Part number 8177 belongs to the DBH line of radial shaft seals. It measures 93.64 mm at the shaft, 142.88 mm at the housing bore and 12.70 mm in height, which puts it on medium and large rotating equipment. The Mx configuration pairs a primary sealing lip with a second lip that keeps dirt out, a useful trait where dust is present. The seal seats in the housing bore and rides the shaft with light radial interference.

Reading the code is straightforward: 8177 is the item number, DBH is the line, and the three figures follow the usual d, D and h order — shaft 93.64 mm, housing 142.88 mm, width 12.70 mm. Mx tells you the lip arrangement: one lip holds the lubricant in, the other blocks incoming contamination. A metal case carries the elastomer, and the elastic element supplies the contact pressure that keeps the lip against the shaft. The compound handles the oils and greases found in most plant equipment; for aggressive media or unusual temperatures, check the manufacturer's data sheet.

Seals in this size range turn up in gearboxes, centrifugal pumps, mixers, belt conveyors and other power transmission drives. Whatever the machine, the job is the same: keep lubricant inside and keep dust, water and particles outside. You will usually find it on a shaft near 94 mm running at moderate speed, where a barrier that needs little attention is what the application calls for.

Before ordering, confirm three things on the equipment: shaft diameter, housing bore and height. Also note the lubricant type and the operating temperature. During installation, lubricate the lip and press on the outer ring only, never on the lip itself. Shaft runout and the finish of the running track both affect how long the seal lasts, since a rough or scored track wears the lip faster. If the seal you are replacing has a different design, compare the section and lip style first.

When you need an equivalent, send part number 8177 together with the measurements you took — shaft, bore and height. A photo of the old seal showing its markings also helps. With that information we can search within the same family or propose a seal with nearby standard dimensions and confirm compatibility against the manufacturer's data.
