When a rotating shaft needs a dependable barrier between lubricant and the outside environment, the DBH 5350Sil radial shaft seal is a direct replacement option. It fits a 55 mm shaft, a 70 mm housing bore and an 8 mm width, and its Lz lip design keeps constant contact on the shaft. This seal helps retain oil and keeps dust, water and particles away from bearings and bushings in pumps, gearboxes and similar equipment.

The DBH 5350Sil is identified by the code 5350Sil and the dimensions shaft 55 mm, housing 70 mm, width 8.00 mm. Its Lz designation refers to a spring-loaded sealing lip that presses against the shaft for consistent sealing. As a DBH part supplied by MR, it carries the original factory markings for traceability. Typical installation points include bearing housings, pumps, gearboxes and electric motors.

Seals in this size range are common in centrifugal pumps, gear reducers, drive shafts, mixers and process machinery. The seal's job is to keep lubricant in and contaminants out, protecting the bearings or bushings from premature wear. It also suits splash-oil systems, dusty environments and assemblies where axial space is tight and the 8 mm width is an advantage.

For correct selection, compare the shaft and housing diameters with those of the seal being replaced. The Lz design calls for a housing with a fillet radius and a shaft surface with suitable hardness and roughness to avoid lip damage. During installation, apply lubricant to the lip and use a proper installation sleeve so the lip does not twist or tear. If the application runs at high peripheral speed or temperature, check the manufacturer's data for the lip material.

If you need an equivalent, send the full seal code, the shaft, housing and width dimensions, and a photo of the part. With that information we can check the DBH line or other options that perform the same function. We can also advise if the Lz design is not the best fit and another lip type or material would work better.
