DBH 8523Vit radial shaft seal — 120 x 150 x 14

DBH 8523Vit belongs to radial shaft seal, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 8523Vit and any equivalents.

The DBH 8523Vit is a radial shaft seal that keeps lubricant inside the housing and blocks dust, water, and other particles from entering equipment with a rotating shaft. It is installed by pressing it into the housing bore, and its flexible lip rides on the shaft to accommodate slight misalignment. As a wear component, it should be replaced when leakage or contamination becomes evident. MR supplies this brand and can help you confirm the correct size for your application.

This oil seal is designated 8523Vit and fits a 120 mm shaft, a 150 mm housing bore, and a 14.00 mm width. The Lx-H-AH configuration includes a metal case and an auxiliary exclusion lip, which helps retain lubricant while keeping contaminants away from the exposed side. Always verify these three dimensions against your existing part or drawing before ordering.

Typical applications include gearboxes, pumps, electric motors, rollers, and transmission equipment where a shaft rotates within a stationary housing. It is also found in agricultural machinery, conveyors, and process equipment operating in dusty or washdown environments. In such conditions, the auxiliary lip of the Lx-H-AH design supports lubricant retention and contaminant exclusion, assuming the shaft surface is in good shape and the speed is appropriate for an elastomeric lip seal.

When selecting a replacement, check the shaft diameter and surface condition—a scratched or worn shaft can destroy the lip quickly. The housing should be clean, without burrs, and deep enough to accept the 14.00 mm width. During installation, lubricate the lip, keep the seal square to the bore, and press on the case using a tube or spacer, never on the lip. If the shaft has excessive play or runout, a different sealing approach may be required.

To request a quote for part number 8523Vit, send the shaft, housing, and width dimensions along with a photo of the part or drawing. We will review the radial shaft seal line and advise whether the Lx-H-AH design fits your needs or if another configuration would be better. We can also help assess shaft and housing condition to prevent repeat failures.

MR supplies the DBH brand within its seals and oil seals line. If you have the part number ready, message us on WhatsApp with the designation 8523Vit and the dimensions, and we will send you a quote. If you are unsure between two sizes, send both and we will help determine which one matches your equipment's housing and shaft.
