5X11MM Ceramic Ball Bearing | MR115 Ball Bearing by ACER Racing

Made from our World Champion Ceramic Nitride Pro Series Bearing Material. 5x11mm CERAMIC BALL BEARING size MR115. This 5x11x4mm bearing is intended for high speed use.

For 5x11mm clutch bearings use part C053
For 5x11x4mm ceramic ball bearing for brushless motors use part C069

This is the equivalent of a Tamiya size 1150 ball bearing

Our MR115 bearing has an inner diameter of 5 millimeters, an outer diameter of 11 millimeters, and a width of 4 millimeters. Its compact size makes it suitable for applications where space is limited and precise motion control is required.

One of the key advantages of the MR115 ceramic ball bearing is its construction material. The balls are made from ceramic, specifically silicon nitride. Ceramic bearings offer several advantages over traditional steel bearings. They have superior hardness, low density, and excellent corrosion resistance, making them ideal for demanding applications.

The ceramic balls in the MR115 bearing provide several benefits. Firstly, they have reduced friction compared to steel balls, resulting in improved efficiency and reduced energy loss during rotation. This leads to enhanced performance and reduced wear on the bearing and surrounding components.

Moreover, ceramic balls have exceptional wear resistance, allowing the MR115 bearing to have a longer service life compared to steel bearings. This translates to reduced maintenance requirements and cost savings for the user.

The MR115 ceramic ball bearing also exhibits excellent temperature stability. Ceramic materials can withstand high temperatures without losing their performance, making them suitable for applications involving high-speed rotation or exposure to extreme heat.

Our MR115 ceramic ball bearing is a high-performance miniature component known for its compact size, reduced friction, wear resistance, temperature stability, and non-magnetic properties. Its ceramic construction offers superior hardness, low density, and excellent corrosion resistance, making it suitable for a wide range of applications. Whether used in precision instruments, RC car applications, robotics, or other high-performance systems, the MR115 ceramic ball bearing continues to deliver reliability, efficiency, and durability.
