Sealing a rotating shaft comes down to matching three measurements and one design style. The DBH 5261 radial shaft seal answers that need: it keeps lubricant where it belongs and blocks dirt, dust and moisture from reaching the bearing. Its Lz lip configuration keeps drag low, which matters on equipment with tight axial room. MR Industrial Accessories supplies this DBH seal and helps buyers confirm the fit before they order.

The code breaks down simply. The 5261 designation identifies the seal itself, while the numbers that follow describe the seat it fills: shaft 25.4 mm, housing 38.07 mm, height 6.35 mm. Get those three figures off the old part or the drawing and the match is straightforward. The Lz design refers to the lip geometry, a style chosen where friction and heat buildup need to stay controlled. Seals in this series leave the factory within the tolerance range set for the line.

Where does a seal this size show up? Pumps, electric motors, gearboxes and compressors are common hosts, along with power transmission drives. Because the cross section is compact, it fits small-diameter shafts where there is little room to work with. Agricultural and industrial machinery running in dusty or damp conditions also uses it, as long as shaft speed and temperature stay within what the lip compound can handle.

Installation rewards a little patience. Wipe the shaft and bore until they are clean and free of nicks or burrs, then coat the lip with the lubricant it will see in service before pressing it in squarely. When selecting a replacement, weigh peripheral speed, running temperature and how the fluid reacts with the elastomer. The Lz profile balances sealing against drag, but the shaft itself needs the right hardness and surface finish or the lip will wear early.

Working from a code or from measurements, either approach works. Send the 5261 reference, or just your shaft and housing dimensions, and the team can cross to alternatives in the same brand or elsewhere in the lines we carry, keeping the critical dimensions intact. Tell us the lubricant and the operating conditions and we can point you toward the design that suits them best.
