Mirka AOS033 Arbor Bearing Cap
The Mirka AOS033 is a replacement arbor bearing cap designed specifically for the 130NV model. It serves technicians and workshops maintaining Mirka pneumatic tools who need to restore original spindle function. This component ensures the correct fit for the designated tool series.
Thermals noise and power draw
As a passive mechanical part the cap generates no heat noise or electrical draw during operation. It simply seats onto the arbor to retain the bearing assembly within the 130NV housing. Normal use places no thermal or acoustic load on the surrounding tool.
Build quality and mounting
The cap is manufactured to Mirka specifications for direct installation onto the 130NV arbor. Its mounting geometry matches the original equipment so reassembly follows the standard service procedure. Proper seating maintains bearing alignment and protects internal components from contamination.

Questions about this item
How is the AOS033 arbor bearing cap installed on the 130NV, and what step is often missed?
Thread the cap onto the 130NV arbor by hand until the bearing seats fully, then tighten with the correct spanner; the step often missed is confirming the bearing sits square before final torque.
What maintenance or replacement will the AOS033 cap need over time?
Inspect the cap threads and bearing surface during routine 130NV service; replace the AOS033 if thread wear, bearing play or corrosion appears.
What limit appears first on the AOS033 cap during sustained 130NV operation?
Heat buildup in the bearing race is the first limit; prolonged high-speed runs can degrade the cap's bearing lubrication faster than the threads wear.
