DBH 1136 radial shaft seal — 49 x 68 x 8

DBH 1136 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 1136 and any equivalents.

The DBH 1136 is a radial shaft seal built to keep oil or grease where it belongs on a turning shaft and to shut out dust and water. Gearboxes, pumps, electric motors and power transmission drives are the usual homes for this type of lip seal. With a 49 mm shaft, 68 mm housing and 8 mm height, it sits in the middle of the size range. MR supplies this brand and can help you confirm the right seal for the job.

Reading the code is the fastest way to check a replacement. The dimensions come in the order shaft, housing and height, so this seal fits a 49 mm shaft in a 68 mm bore with an 8.00 mm width. The Lx-R H designation points to a single lip with a spring, which holds lubricant back in one direction. The elastomeric lip rides on the shaft while the metal case stays press-fitted in the housing. Like any wear part, it earns replacement once grease starts escaping or contamination gets past it.

You will run into this seal in gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. Machine tools, conveyors and agro-industrial machinery also use it wherever a rotating shaft needs separation from its surroundings. Its job is to hold the lubricant in and keep the bearing or bushing beside it working properly. In dirty or wet conditions, it pays to check whether the lip style suits the environment.

Fitting matters as much as the part. Confirm the shaft matches the stated dimension and shows no scratches or burrs, since even a light score on the sealing track will speed up leakage. Coat the lip with lubricant before pressing the seal in, and drive it with a tube that contacts the case rather than the lip. Keep the housing clean and burr-free. A worn shaft can be handled with a repair sleeve. Speed, temperature and the fluid being retained all feed into the final selection.

For an equivalent, send the code DBH 1136 together with the shaft, housing and height figures. A photo of the removed seal or the housing drawing works just as well. With those details we check options in the same seals and oil seals category. MR can also point you toward the lip design that best matches your equipment.

Just send DBH 1136 over WhatsApp and we take it from there, looking for a matching size or another brand in the same category. The more you share about dimensions, fluid, temperature and speed, the closer the proposal will be. We can also walk you through installation and the tools that keep the lip intact during fitting.
