The DBH 8008Pol is a radial shaft seal sized for a 40.00 mm shaft, a 52.00 mm housing bore and a 9.00 mm width, built in the Lx-Bidi configuration. Its job is to hold lubricant inside rotating equipment while keeping dust, water and particles out, and its lip seals in both directions of rotation. Because it is a wear part, leakage or contamination at the seal area is the signal to replace it. MR supplies this brand and can help confirm the correct seal for the application.

Reading the designation: 8008Pol identifies the size and construction within the DBH line, while Lx-Bidi describes a sealing lip that works in either direction of rotation. The seal combines a metal body with an elastomer element. Shaft 40.00 mm, housing 52.00 mm, width 9.00 mm: these three values are what you check against the shaft and bore before ordering.

Typical locations include gearboxes, pumps, electric motors, transmission shafts and process equipment where oil or grease has to stay contained. It also suits shafts that reverse direction or move back and forth, since the lip seals both ways. Maintenance teams run into this size often when repairing machinery built around 40 mm shafts.

Before installation, confirm the shaft is clean and free of burrs or marks and that the housing bore is not deformed. Apply lubricant to the lip, then press the seal in squarely, using a driver that will not cut the elastomer. If the shaft surface is worn, an extra-lip version may be worth considering. Speed, temperature and the lubricant in use all influence the final selection.

For an equivalent, send the code 8008Pol or the three dimensions. The equipment part number or a photo of the old seal works too. The team compares the options and confirms the one that fits your application.

Catching lubricant leakage or contaminant ingress early protects bearings and gears from further damage. Send the code 8008Pol by WhatsApp or email and the team will get back to you with a quote.
