The DBH 5701 is a radial shaft lip seal built to keep lubricant inside a housing and keep dust, water and other contaminants out. It fits a 44.45 mm shaft in a 68.22 mm bore, with a 12.70 mm height, and uses the Lz lip design. Seals like this one sit at the point where a shaft leaves a housing, so they carry much of the responsibility for protecting the bearings and bushings behind them. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

Reading the code is straightforward. The 5701 identifies the item within the DBH line, and the three numbers that follow describe the geometry: shaft 44.45 mm, housing bore 68.22 mm, overall width 12.70 mm. The Lz designation refers to the lip configuration, which is matched to rotating service. When you compare a seal against a housing drawing, these are the three values to check first, since a mismatch on any one of them will prevent a proper fit.

You will find seals in this size range on gearboxes, centrifugal pumps, speed reducers, electric motors and other power transmission equipment. In every case the job is the same: hold oil or grease in, keep particles out, and reduce the wear that reaches the bearings and bushings. Because a failed seal often shows up as a leak or as premature bearing noise, it belongs on any preventive maintenance schedule for industrial and agricultural machinery.

Installation decides how long the seal lasts. Confirm the shaft is at 44.45 mm and the bore at 68.22 mm, check that the surface is smooth and free of burrs or nicks, and make sure the 12.70 mm width matches the housing depth. Apply lubricant to the lip before pressing the seal in, and use an installation sleeve so the lip is not rolled or cut on the shaft edge. If the shaft itself shows a wear groove, an auxiliary lip may be the better choice.

If you are replacing an original part, send the code 5701 or the dimensions of the seal you removed. The team compares them against the matching options in the DBH line and the other seal lines we carry, and can point you toward a lip design suited to your lubricant and shaft speed. Quotes are handled by WhatsApp or email with the part number, and we reply promptly.

Seals, bearings and power transmission components are what we do, so a seal inquiry usually turns into a short conversation about the surrounding assembly. If you are unsure whether the 5701 is the correct replacement, the dimensions and a photo of the housing are usually enough for us to confirm it.
