MG elastomer bellows seals
MG1, MG12, MG13, MG1S20 and MG912 equivalents. Dimensions and limits for the MG1 family are on the MG1 / MG12 / MG13 page.
Replacement seals built to Burgmann and EagleBurgmann designs: elastomer bellows seals, spring seals and double seals, made in-house at manufacturer-direct pricing.
We build most Burgmann seals, not only the types named on this page. Send the seal part number, a drawing or the old seal.
At a glance
We are the manufacturer, not a reseller — we build in-house and supply at quantities that work for a distributor, an OEM or a maintenance department.
Range
Equivalents across the Burgmann range, OEM-compatible or fully custom.
MG1, MG12, MG13, MG1S20 and MG912 equivalents. Dimensions and limits for the MG1 family are on the MG1 / MG12 / MG13 page.
M3, M7N, H7N, H12N, HJ92N and M74D equivalents, listed with their limits in our catalog.
Discontinued or non-standard Burgmann seals machined from a drawing or a sample of the old seal.

Drawings & dimensions
The catalog models in the table above, with their section drawings. Dimensions in mm unless a table says inches. Inch sizes are named by the nominal shaft size in inches; d1 gives the same size in mm. Letters match the section drawing. Standard sizes shown; other sizes are built from a drawing or the old seal.
