The MR128 is a compact miniature ball bearing with an 8mm bore and 12mm outer diameter, measuring just 2.5mm in width. Made from chrome steel, it’s built to handle radial loads up to 104 lbf while spinning smoothly at speeds up to 40,000 RPM.
Its open design and stainless steel cage make it easy to maintain, though regular lubrication is needed for optimal performance. The bearing operates well in temperatures ranging from -30°C to 110°C.
With a lightweight design at only 0.7g, it’s ideal for small, precision applications like hobby motors or delicate instruments. Compliant with RoHS and REACH standards, it’s a reliable choice for various lightweight mechanical needs.
The ABEC1 tolerance ensures decent precision, while the MC3 radial clearance provides smooth operation. Its simple, single-row construction makes it easy to install and replace in tight spaces.
