The DBH 1139 oil seal is a radial lip seal, with dimensions of 35 mm shaft, 63 mm housing and a height of 10.00/16.00 mm. Its A 103 Bidi design indicates that it has two lips, one main and one secondary, to improve sealing in applications with greater contamination or demand. It is used in equipment where lubricant must be retained and the entry of dust or water prevented, such as pumps, electric motors, gearboxes and bearings. MR Accesorios Industriales supplies this official brand and advises you to choose the correct oil seal.

This item is a DBH radial shaft seal, code 1139, with the following dimensions: shaft diameter 35 mm, housing diameter 63 mm and height 10.00/16.00 mm. The A 103 Bidi design corresponds to a double-lip oil seal, with a main sealing lip and a secondary lip that acts as a wiper or additional barrier. The variable height (10 to 16 mm) allows the oil seal to adapt to housings with different mounting depths, as long as the nominal dimension is respected. It is a common replacement part in rotating equipment.

Typical applications of this oil seal include centrifugal pumps, electric motors, gearboxes, gear cases, rollers and transmission shafts. In all these cases, the oil seal fulfills the function of retaining the oil or grease inside the assembly and preventing external particles from entering. The double lip is especially useful in environments with dust, chips or water, where a single oil seal would not achieve the same level of protection. It is also used in equipment in the food, chemical and process industries, as long as the lip material is compatible with the fluid.

To correctly select this oil seal, take into account the shaft dimension, the housing diameter and the width of the available space. Verify that the shaft surface is in good condition, without scratches or wear, and that the housing has the proper chamfer so the lip is not damaged during installation. Lubricate the lip with the same grease or oil as the equipment before inserting it. If the equipment operates at high speed or temperature, consult MR to evaluate the lip material and the spring type.
