Part number 1313 belongs to the DBH line of radial shaft seals. This one fits a 92 mm housing bore and measures 10 mm in height, and it carries the A 378 design, a single-lip layout with a metal case built for rotating shafts. Seals like this one are wear items: once lubricant starts seeping out or grit works its way in, replacement is the fix. MR supplies this brand and helps you match the seal to your equipment.

Reading the reference is straightforward. The 1313 code identifies the item within the DBH series, while the two figures that matter for fit are the 92 mm housing diameter and the 10 mm height. The A 378 designation describes the geometry: one lip, metal outer case. The shaft diameter is verified against the manufacturer's data sheet before any quote is issued, so it is worth having that measurement on hand.

Seals in this category show up in centrifugal pumps, electric motors, gearboxes, conveyor rollers and other power transmission assemblies. Their job is always the same: hold the lubricant in and keep dust, water and particles away from the bearings. You will also find them in agricultural machinery, industrial washing equipment and ventilation systems running continuous shafts.

Installation rewards care. Inspect shaft roughness and condition, check that the housing is concentric and keep every component clean. Lubricate the lip before pressing the seal in, and apply force on the case only, never on the lip. A worn shaft can often be brought back into tolerance with a wear sleeve or repair sleeve. Speed, temperature and the fluid being sealed all influence selection, and those values are checked against the data sheet.

Looking for an equivalent? Send part number 1313 together with the housing and shaft dimensions, a photo of the seal and the equipment it serves. That is enough to search within the same series or across other brands. Mentioning the fluid and the operating temperature also helps narrow down the lip material.

Quotes are handled by WhatsApp or email at MR. Send the part number and the team will review the request and come back with the options. If your shaft diameter differs from the one listed, say so in your message so the seal is right the first time.
