The DBH 5749 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering rotating equipment. Its dimensions of 101.60 mm shaft, 130.17 mm housing and 14.28 mm height place it in large-shaft applications, where sealing is critical to protect bearings and extend the service life of the assembly. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right seal for your equipment.

This item is a radial shaft seal from the DBH line, identified by part number 5749. Its nominal dimensions are 101.60 mm shaft diameter, 130.17 mm housing diameter and 14.28 mm height. The Lz design corresponds to a single lip configuration with spring, intended to retain oil or grease on rotating shafts. The 5749 designation is the reference you will find on the manufacturer's product page and the one you should quote when asking about equivalents or replacements.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, mills, mixers and power transmission equipment in general. In all cases it performs the same function: keeping lubricant inside the assembly and blocking dust, water or particles that could accelerate bearing wear. It is a wear part, so it should be checked at every preventive maintenance interval and replaced at any sign of leakage or lip hardening.

To correctly select a radial shaft seal, take into account the shaft rotation speed, working temperature, type of lubricant and the surface condition of the shaft. The shaft diameter must be within the recommended tolerance and free of deep marks, because the lip seals against that surface. The housing must also be clean and free of burrs. During installation, lubricate the lip and use a suitable installation tool to avoid damaging it. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.

If you need an equivalent or a different size, the most practical approach is to send us part number 5749 together with the dimensions of your shaft and housing, and a photo of the old part if you have one. With that data we can look for an alternative within the same DBH line or from another brand we supply. We can also advise you if the Lz design is not the most suitable for your application and it is better to move to another lip type or material.
