Key specifications

Available sizes

Model codes are the Seagull size codes; the SKU is the AIMS part number.

Selecting the right option

Choose the size from the options list. The first number is the shaft diameter and the second is the housing bore, both in millimetres. Width is 15 mm for every size on this page.

Match the shaft diameter, the housing bore and the width. Go by the shaft and bore rather than the lip of the old seal, as the lip sits slightly smaller than the shaft it seals on. Width is usually the least critical of the three, provided the housing has the depth.

Type TC is the double lip version, with a second lip on the outer side that helps keep dust and dirt off the main lip; type SC is single lip, suited to cleaner conditions.

NBR suits mineral oils and greases in general machinery. If the seal runs hot or meets aggressive fluids, look at the Viton version of the same size range.

If the size you need is not listed, send AIMS the shaft diameter, housing bore and width and we will check what is available.

Fitting and use

Fit the seal with the main lip facing the fluid you are keeping in, press it in square using a tool that bears on the outer face of the seal, and avoid hammering directly on the seal.

Lubricate the lip with the system oil or grease before assembly, and cover keyways, splines, threads or sharp shoulders with a sleeve or tape so they cannot cut the lip as it passes over.

Run the seal on a clean, smooth shaft with a lead-in chamfer and no burrs. A shaft finished to ISO h11 is the usual guide for rotary shaft seals.
