The DBH 1159 oil seal is a single lip radial seal with Mx design, intended for rotating shafts of 85 mm diameter. It mounts in 105 mm housings and has a 10 mm height. Its function is to retain lubricant and prevent the entry of dust, water or particles in gearboxes, pumps and industrial equipment. It is a wear part that should be replaced when oil leakage appears or play or roughness is detected on the shaft raceway.

The DBH 1159 is a radial shaft seal with Mx design, with the following dimensions: shaft diameter 85 mm, housing diameter 105 mm and height 10.00 mm. The Mx design corresponds to a sealing lip with spring, suitable for rotating shafts with lubrication. The DBH brand is an official brand that MR carries, so the replacement is available with the exact designation 1159 or its dimensional equivalent. The manufacturer's nomenclature may vary by batch, but the dimensions are what define interchangeability.

This type of seal is used in gearboxes, centrifugal pumps, electric motors, conveyor rollers and transmission equipment. It also appears in road, agricultural and process line machinery where shafts rotate inside a lubricated housing. As a sealing component, its service life depends on rotation speed, temperature, pressure and the surface condition of the shaft. Therefore, it should be checked every time the equipment is disassembled.

For installation, verify that the shaft has no burrs or deep marks in the contact area: a scratched raceway wears the lip prematurely. Lubricate the lip with the same oil used in the equipment before inserting it and place the seal perpendicular to the shaft, without hitting it unevenly. If the housing is damaged, consider using a seal with a sleeve or a repaired seat. Selection is defined by the d, D and h dimensions, plus the type of elastomer and spring.

If you need a nearby size or an equivalent from another brand, send us the code 1159 and the shaft, housing and height dimensions. With that data we can look for an alternative with the same Mx design or suggest a seal with similar characteristics. We can also guide you if space is limited or if the equipment operates at high temperatures. You do not need the manufacturer's data sheet: the dimensions are enough to identify the replacement.

MR Accesorios Industriales carries DBH seals and other brands in the industry. If you want to request a quote, send the code 1159 via WhatsApp along with a photo of the old seal or the dimensions taken with a caliper. That way we will respond with the option that best fits your equipment.
