The DBH 6249 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering rotating shafts. Its dimensions of 18.80 mm shaft diameter, 25.80 mm housing bore and 7.00 mm height place it in compact low- and medium-speed applications. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for minor misalignment. It is a common replacement part in pumps, electric motors and gearboxes.

This item is a radial shaft seal from the DBH brand, identified by code 6249. Its dimensions are 18.80 mm shaft diameter (d), 25.80 mm housing bore diameter (D) and 7.00 mm height (h). The Lt design corresponds to a single-lip configuration with spring, suitable for retaining oil or grease on rotating shafts. The 6249 nomenclature follows the manufacturer's size-based designation system and should not be confused with bearings of the 62 series: this is a seal, not a bearing.

Typical applications for this seal include small centrifugal pumps, low-power electric motors, speed reducers, gearboxes and transmission equipment. It is also found in machine tools, compressors and lubrication systems where radial space is limited. Its main function is to keep lubricant inside the assembly and block dust, water or particles that could damage nearby bearings or gears.

To correctly select a seal such as the 6249, verify that the shaft diameter is within the recommended tolerance and that the contact surface is polished and free of grooves. The housing must have the proper diameter and depth to accommodate the 7.00 mm height without deforming the lip. During installation, lubricate the lip with the same service oil or grease, avoid striking it and make sure the spring is on the fluid side to be retained. If the shaft shows wear, consider a repair sleeve.

If you need a nearby size or an equivalent to the 6249, the most practical approach is to send us the complete code and the dimensions of the original seal. You can also provide the shaft and housing dimensions and the available height. With that data, at MR Accesorios Industriales we review alternatives within the same seal category and confirm compatible options. If the original seal has no visible brand, a photo and a caliper are usually enough to identify it.
