MR62ZZ 2x6x2 Metal Shielded Precision Mini Ball Bearings 10pc

Keep your builds running smoothly with the MR62ZZ 2x6x2 Metal Shielded Precision Mini Ball Bearings. These compact steel bearings measure just 2mm inner diameter × 6mm outer diameter × 2mm width, making them an ideal solution for tight-tolerance applications in RC models, hobby motors, miniature machinery, 3D printers, and small mechanical assemblies.

Constructed from high-grade steel with dual metal shields (ZZ designation), these precision bearings keep contaminants out while retaining lubrication — delivering consistent, low-friction rotation in even the most demanding compact applications.

Key Features

• Precision MR62ZZ Standard: Manufactured to tight tolerances for smooth, reliable rotation cycle after cycle.
• Dual Metal Shields: ZZ-rated steel shields on both sides protect internal components from dust and debris.
• Compact Dimensions: 2mm bore × 6mm OD × 2mm width — ideal for space-constrained mechanical designs.

Frequently Asked Questions

Q: What does "MR62ZZ" mean in the bearing designation?

A: The "MR62" identifies the bearing series and dimensions (2mm inner diameter × 6mm outer diameter × 2mm wide), while "ZZ" indicates that the bearing is fitted with dual metal shields on both sides to protect the internal balls and races from dust and debris.

Q: How many bearings come in a pack?

A: Each order includes 10 pieces of MR62ZZ 2x6x2 metal shielded precision mini ball bearings, giving you ample stock for repairs or multiple projects.

Q: What applications are these MR62ZZ mini bearings suitable for?

A: These precision mini ball bearings are widely used in RC cars, drones, 3D printers, hobby motors, miniature robots, fidget spinners, and any compact mechanical assembly requiring a 2mm bore bearing with a 6mm outer diameter.

Q: Are the MR62ZZ bearings pre-lubricated?

A: Yes — these bearings come pre-lubricated and are ready to install immediately. The dual metal shields help retain the internal lubricant and keep out contaminants for long service life.
