DBH 6603Sil belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 6603Sil and any equivalents.

The DBH 6603Sil is a radial shaft seal built to sit in a housing bore and run against a rotating shaft, holding lubricant in and keeping dust, water and particles out. Reading its code gives you the three key measurements: 120 mm at the shaft, 150 mm at the housing and 12 mm of height. Gearboxes, pumps and other shaft-driven equipment in that size range commonly use this seal as a replacement item.

Shaft 120 mm, housing 150 mm, height 12.00 mm. The Lx designation refers to a single lip with a spring, a configuration meant for rotating shafts under permanent lubrication. The outer body presses into the housing with an interference fit and stays put, while the flexible lip tracks the turning shaft. This item belongs to the seals and radial shaft seals category and carries the DBH brand, which MR supplies.

Seals in this size range turn up in gearboxes, centrifugal pumps, large electric motors, rollers, and belt or chain driven equipment. The job is the same everywhere: hold oil or grease inside the housing and stop the outside environment from reaching the lubricant. In washdown areas or dusty conditions, the seal also acts as a barrier alongside a bearing or bushing.

When matching a seal, confirm the shaft and housing diameters against the designation and check that the height fits the housing depth. Look at the shaft surface as well, since scratches or wear shorten lip life. Lubricate the lip before fitting, drive the seal in with a tool that contacts the outer edge rather than the lip, and remove any burrs from the shaft before sliding the seal into place.

For a quote, share the code stamped on the old seal plus caliper readings for shaft, housing and height. That is usually enough for us to find the equivalent designation in the same series or suggest a compatible option. If the code has worn off, a photo of the housing and shaft helps us confirm the lip configuration and material.

Send the DBH 6603Sil code by WhatsApp to MR Industrial Accessories and our technical team will review it and come back with the option that fits your equipment. Assembly drawings or housing measurements are also welcome if you want help narrowing down the right seal.
