The DBH 5374 is a radial lip seal that keeps lubricant where it belongs while blocking dust, water and other contaminants from reaching a rotating shaft. Its dimensions are 65 mm at the shaft, 85 mm at the housing and 12.00 mm in height, and it carries the Lz designation. MR Industrial Accessories supplies this brand and can confirm the size or an equivalent before you commit to an order.

Reading the reference is straightforward. The 5374 identifies the item within the DBH line, while the three figures describe where it fits: 65 mm shaft (d), 85 mm housing (D) and 12.00 mm height (h). The Lz design points to a single sealing lip combined with an outer metal case, giving the seal a compact cross section that suits standard bores and shafts finished to a proper surface quality.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, rollers and other power transmission assemblies. The job is always the same: hold the oil or grease in and keep outside contamination out. You will also find them used as a secondary barrier in bearing housings and bushings that see continuous rotation.

Installation rewards a little care. Confirm the shaft diameter and finish, make sure the bore is clean and free of burrs, and lubricate the lip before the shaft passes through it. Press on the outer diameter with a proper installation tube rather than on the lip. On equipment that runs with strong vibration or elevated temperature, review the elastomer hardness and spring type before selecting the replacement.

For a cross-reference, send part number 5374 together with the shaft, housing and height measurements. With those three values we can work through the DBH series and propose alternatives that match. We can also look at the Lz configuration and discuss lip or material options based on the fluid and the operating conditions of your equipment.
