The MR105ZZ Deep Groove Ball Bearing is a compact stainless steel bearing designed for smooth and reliable rotational movement in small mechanical systems. With a 5mm inner diameter, 10mm outer diameter and 4mm width, BDTronics offers this miniature bearing for robotics, 3D printers, RC models, motors, small machinery and DIY mechanical projects.

Manufactured from stainless steel, the MR105ZZ provides good corrosion resistance and durability for applications where compact size and dependable rotation are required. The ZZ double metal shields help protect the internal bearing components from dust and debris while retaining the bearing's lubrication.

Applications:

The MR105ZZ is suitable for 3D printers, robotics, RC cars, RC airplanes, small motors, miniature gearboxes, wheels, rollers, CNC mechanisms, electronic equipment, model making and DIY mechanical projects.

Its small 5 × 10 × 4mm dimensions make it particularly useful for compact mechanisms where installation space is limited.

Installation:

Install the bearing into a properly sized shaft and housing. Apply even pressure to the appropriate bearing ring during installation to avoid damaging the balls, shields or raceways. Ensure the shaft and housing are correctly aligned for smooth rotation.

Important Notes:

• Verify the 5mm × 10mm × 4mm bearing dimensions before ordering.

• ZZ shields are designed primarily for protection against dust and contaminants and are not intended as a completely sealed waterproof barrier.

• Avoid excessive impact or side loading during installation.

• Use the bearing within the mechanical and speed requirements of your application.
