When a small shaft needs a reliable barrier between the lubricant and the outside world, the DBH 5140 radial shaft seal is the part to look at. It measures 16.50 mm at the shaft, 30.00 mm at the housing and 7.00 mm in height, which puts it in compact assemblies such as electric motors, pumps and small gearboxes. MR Industrial Accessories supplies this line and can help you confirm the right seal for the job.

The 5140 designation belongs to the DBH line of radial shaft seals. Four values tell you whether it will fit: d = 16.5 mm (shaft), D = 30 mm (housing) and h = 7.00 mm (height), plus the Lz design, which sets how the lip and outer body are shaped. Check all four against your bore and shaft before ordering.

Seals in this size range turn up in small electric motors, centrifugal pumps, gear reducers, compressors, fans and power transmission equipment. The job is always the same: hold oil or grease in and keep dust, water and particles out. Machine tools, washing equipment and irrigation systems also use them where shaft speed is moderate and temperature stays steady.

Getting the fit right matters more than the brand on the box. The shaft, housing and height must match the seal, and the Lz design affects both the lip profile and how the seal seats. If you are swapping out a seal from another maker, compare the data sheet first. Lubricate the lip before pressing it in, use an installation tool rather than a hammer, and check that the shaft is not scratched and the housing is not oval, since either will cut the seal's working life.

From there we compare options in the same seal category and confirm the one that matches your equipment without giving up sealing performance or assembly tolerance.
