The DBH 6744 radial shaft seal is a lip seal that stops lubricant from escaping and blocks dust and water from entering rotating shafts. With its dimensions of 17.50 mm shaft, 35.00 mm housing and 7.00 mm height, in Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales sells it as part of its seals and oil seals line for maintenance and replacement.

The DBH 6744 is a single-lip radial shaft seal with a spring, identified with the Lx design. Its nominal dimensions are 17.50 mm shaft diameter (d), 35.00 mm housing diameter (D) and 7.00 mm height (h). The flexible lip, supported by a steel spring, keeps contact against the rotating shaft and compensates for small misalignments. The rigid outer body is press-fitted into the housing and seals the static part. It is a wear part: over time the lip hardens or wears and starts to leak oil.

It is used in equipment where a shaft rotates inside a housing with lubricant. It appears in gearboxes, centrifugal pumps, electric motors, compressors, mixers and machine tools. Also in power transmission applications where grease or oil must be retained and contaminants kept out. Because of its compact size, it is common in low and medium power equipment, and in replacements for imported machinery where mounting space is limited.

To choose the correct seal, check that the shaft diameter is within the recommended tolerance and that the contact surface is ground and free of grooves. The housing must have the right diameter and depth to accommodate the 7.00 mm height. During installation, lubricate the lip with the same service oil or grease, avoid hitting it and use a support tube to insert it perpendicular. If the shaft shows wear, consider a repair sleeve or a nearby size.

If you need a seal equivalent to the 6744 or a close size, send us the part number, the shaft, housing and height dimensions, and a photo of the part. With that data we look for alternatives in the same series or in other brands we carry. We can also advise you on the most suitable lip design according to the type of lubricant, speed and working temperature. The idea is that you don't have your equipment down for a wear part.
