When a rotating shaft needs its lubricant kept in and dirt kept out, a radial shaft seal like the DBH 5141 does that job. The code 5141 covers a seal built for a 50 mm shaft, a 72 mm housing bore and a 10 mm height, in the Lz design. MR Industrial Accessories supplies this brand and can help you match the seal to your equipment.

Reading the number is the first step. The 5141 code identifies this radial shaft seal; the three figures that matter on the bench are d = 50 mm for the shaft, D = 72 mm for the housing and h = 10.00 mm for the height. The Lz design means a sealing lip backed by a spring, so the lip stays in contact with the shaft as it turns. The elastomer compound handles oils and greases, while the metal case holds its shape when pressed into the bore.

You will find seals of this type on gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment. In each case the goal is the same: keep the lubricant where it belongs and stop dust, water or particles from reaching bearings and gears. Agricultural machinery, food processing lines and general power transmission drives are common places to run into it.

Choosing the right seal comes down to a few checks: shaft and housing dimensions, the lubricant in use, the temperature the seal will see and the peripheral speed of the shaft. The Lz design fits moderate-speed duties where dust or dirt is present. At installation, inspect the shaft for burrs or marks, coat the lip with the same oil used in the equipment, and press the seal in square to the shaft instead of hammering on it.

If the exact seal is not what you need, the code 5141 or the size 50x72x10 is enough for us to look for a close match in another brand or lip configuration from our seal line. We can also point you to the lip design that suits your operating conditions. Send the part number on WhatsApp or by email and our team replies with the information you need to move ahead.

Beyond seals, MR Industrial Accessories covers bearings, mounted units and housings, power transmission components such as chains, sprockets, sheaves, belts and couplings, plus lubrication and maintenance tools, serving customers in the United States and several Latin American countries.
