The DBH 6887 is a radial shaft seal built for rotating shafts in industrial equipment. It keeps lubricant in and contaminants out, with a metal case and a spring-loaded lip that maintains contact even under slight misalignment. The listed dimensions are 48.70 mm for the shaft, 58.00 mm for the housing, and a height of 5.50/8.50 mm.

This seal follows the A 131 design: a single lip, a metal outer case, and a garter spring. The dual height value (5.50/8.50 mm) reflects the lip's ability to flex while staying sealed, which helps when the shaft has minor runout or eccentricity. It is a direct replacement for worn seals in gearboxes, pumps, motors, compressors, and conveyor rollers.

When installing, first clean the shaft and housing bore to remove burrs or old seal material. Apply a thin film of the system's lubricant to the lip before pressing the seal in place. Use a tool that contacts only the outer case—never the lip—to avoid damage. If the shaft surface is grooved, consider repositioning the seal or using a wear sleeve.

To request a quote, send the part number 6887 or the three dimensions via WhatsApp or email. If you have the old seal, a photo helps confirm the profile. Our team can suggest equivalents from the same series or other brands, as long as the mounting dimensions match.

This seal is a maintenance item: check it when you notice leaks, increased bearing temperature, or after a set number of operating hours. Replacing it before failure protects adjacent bearings and reduces downtime.
