The DBH 8730 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 25.5 mm shaft diameter, 58.7 mm housing diameter and 7 mm height, and design A 146, it is press-fitted into the housing and runs against the shaft. It is a key component in pumps, electric motors, gearboxes and power transmission equipment, where it prevents leaks and protects bearings. At MR Accesorios Industriales we sell it as an official brand.

This item is a radial shaft seal from the DBH brand, identified by code 8730. Its dimensions are 25.5 mm shaft diameter (d), 58.7 mm housing diameter (D) and 7.00 mm height (h). Design A 146 corresponds to a specific construction configuration from the manufacturer. The sealing lip, generally made of elastomer, runs on the rotating shaft, while the outer diameter fits into the housing. It is a standard replacement part in equipment with rotary motion.

Typical applications for this seal include centrifugal pumps, electric motors, gear reducers and gearboxes, compressors, and power transmission equipment in general. In all these cases, the seal retains the lubricating oil or grease and prevents the entry of dust, water or particles that accelerate wear on bearings and gears. It is also used on fan, mixer and conveyor shafts, where sealing reliability is critical to avoid unplanned downtime.

To correctly select a seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. Design A 146 may have variants in lip type and material, so it is important to confirm the application and working conditions (speed, temperature, fluid). During installation, lubricate the lip with the same lubricant used in the equipment, insert it perpendicular to the shaft and avoid striking it. If the shaft shows wear or grooves, consider repairing it or using a seal with an auxiliary lip.
