This item is a DBH radial shaft seal, identified with the designation 8577Pol. Its main attributes are: shaft diameter (d) of 51 mm, housing diameter (D) of 70 mm and height (h) of 11.00 mm. The Lx-H-H design indicates a single-lip configuration with spring, suitable for retaining lubricant on rotating shafts. The DBH brand is a brand that MR carries, which technically supports your projects.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the seal prevents oil loss and protects bearings and gears from dust and moisture. It is a critical part in industrial maintenance, since its failure can cause unplanned downtime and costly machinery damage.

For installation, verify that the shaft and housing are clean and free of burrs. Lubricate the seal lip with the same oil or grease it seals before installation. Insert the seal perpendicularly, using a suitable mounting tube that presses on the outer diameter, never on the lip. Make sure the 11 mm height matches the housing depth to prevent leaks or displacement.
