MR104ZZ 4x10x4mm Shielded, Low-Runout Bearing Built for Note-Counting Machines Miniature Ball Bearing

Low-Runout Design for Sensitive Counting Mechanisms
The MR104ZZ (4x10x4mm) is built with tightened radial clearance control, targeting the precision demanded by note-counting and cash-processing machinery where even small bearing play can cause misreads.

Engineered for Financial Equipment
Beyond note counters, this size is equally suited to compact printers and 3D-printer feed systems, giving buyers a single SKU that can cover several adjacent product lines.

Shielded for Continuous-Duty Reliability
Double-side metal shields keep paper dust and fine debris away from the balls and raceway, supporting the long unattended runtimes typical of high-throughput banking and retail cash equipment.

Manufactured to Consistent Standards
Each lot is verified for bore/OD tolerance and shield fit, so machine builders can standardize on this part across multiple models without redesigning the housing or re-qualifying suppliers.

Built for Financial-Sector Qualification
Documentation covering material, hardness, and runout is available to support the supplier qualification processes typical of banking and financial equipment manufacturers before a production order is placed.
