Key Features
Overview
The Mirka AOS054 Spacer 17 x 21.8 x 0.05 mm for AOS 130NV is a replacement spacer made for Mirka’s AOS 130NV. This is a spacer designed for fitment and service use within the AOS 130NV tool setup. Model Number: AOS054. If you are maintaining or repairing that specific Mirka unit, using the correct spacer size helps avoid stack-up issues that can come from using generic shims or mismatched parts.
What matters here is precision. The listed dimensions of 17 x 21.8 x 0.05 mm tell you this is not a general-purpose hardware-store part. It is a thin, application-specific component intended to match the original design of the tool. On service parts like this, the exact thickness is usually the difference between proper assembly and a tool that does not sit, align, or operate the way it should.
Because this is a Mirka replacement part, it makes the most sense for owners, repair techs, and serious users who want to keep an AOS 130NV in proper working order rather than guessing with a substitute. That is especially important on compact sanding equipment and precision air tools, where small internal parts can affect spacing, movement, and long-term wear.
The straightforward value of the Mirka AOS054 Spacer 17 x 21.8 x 0.05 mm for AOS 130NV is that it solves a very specific problem: replacing a missing, worn, or damaged spacer with the correct part number. There is no fluff here. If your service work calls for AOS054, this is the part you want.
