  • MR105ZZ Miniature Single Row Deep Groove Ball Bearing. It is a 5x10x4 Millimeters Mini Ball bearing.
  • These bearings are pre-lubricated with grease.
  • This size is used in several designs of Reprap direct drive extruder because it can fit the end of a 5mm stepper motor shaft.
  • Its chrome steel construction makes it durable and resistant to deformity under heavy loads. 

MR105ZZ Double Shielded Miniature Ball Bearing (5x10x4 mm)

This a a MR105ZZ Double Shielded Miniature Ball Bearings has deep groove geometry for high speeds and supporting both radial and axial loads.

This deep-groove shielded ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed.

The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

Each bearing has a HIGH load carrying capacity, which is around 250 kg to 500 kg.

What is the purpose of a MR105ZZ bearing?

  • The MR105ZZ bearing is a type of miniature ball bearing that is used to support and guide rotary or linear motion in a variety of applications. It is typically used in small and compact mechanical assemblies, such as hobby projects, toys, and other devices that require low-friction movement.

What are the dimensions of a MR105ZZ bearing?

  • The MR105ZZ bearing has an outer diameter of 10 mm, an inner diameter of 5 mm, and a width of 4 mm. These dimensions make it suitable for use in compact mechanical assemblies where space is limited.

What is the maximum load capacity of a MR105ZZ bearing?

  • The maximum load capacity of a MR105ZZ bearing depends on several factors, including the size, material, and design of the bearing, as well as the speed and direction of the load. In general, miniature ball bearings have lower load capacities compared to larger bearings, and it is important to choose a bearing that is capable of handling the expected loads for a given application.
