A rotary shaft needs a seal that holds lubricant in and keeps contaminants out, and the DBH 6261 does exactly that. It is a lip seal with a spring-loaded sealing lip, sized for a 20.00 mm shaft, a 41.30 mm housing bore and a 6.70 mm height. The seal sits pressed in the housing and rides against the rotating shaft, so it wears over time and is normally replaced once leakage or noise shows up.

The reference 6261 belongs to the DBH line of radial shaft seals. Reading the dimensions in order: shaft 20.00 mm, housing 41.30 mm, height 6.70 mm. The Lz execution means one sealing lip with a spring, a common choice for lubricated rotating shafts. When you look up the replacement, the number 6261 is what identifies the exact part on the manufacturer's data sheet.

Typical installations include gearboxes, pumps, electric motors, transmission shafts and bearing arrangements. The lip keeps oil or grease where it belongs and blocks dust, chips and water from reaching the bearing. In dirty or wet surroundings this protection matters for bearing and shaft life. The design also suits cases where only a small pressure difference exists across the seal.

Before pressing the seal in, check that the shaft surface is clean and free of burrs or scratches, and put a little lubricant on the lip. The housing bore must be machined to the stated diameter, and the 6.70 mm height tells you how much axial room the seal needs. A worn shaft may call for a seal with an auxiliary lip. Speed, temperature and lubricant type all influence the final selection.

If you are looking for a cross-reference to the DBH 6261, send the full part number along with the shaft, housing and height measurements, plus a photo of the old seal. That information lets us search other brands and series for a match. We can also tell you whether the Lz design fits your operating conditions or whether another lip configuration is worth considering.
