Metric Size Standard Miniature Ball Bearings MR104zz

Metric Size Standard Miniature Ball Bearings MR104zz

The MR104zz is a compact metric ball bearing, measuring just 4mm by 10mm by 4mm, with a shielded design for added protection. Made from chrome steel, it handles radial loads up to 136 lbf and spins smoothly at speeds up to 48,000 RPM.

Its stainless steel cage and shields keep dirt out while maintaining low friction. The bearing requires lubrication for optimal performance and works in temperatures from -30°C to 110°C.

With a 4mm bore and ABEC1 tolerance, it’s a reliable choice for small machinery or precision tools. The lightweight design (1.33g) makes it ideal for applications like drones or small motors where space is limited.

Compliant with RoHS and REACH standards, it’s a safe and durable option for various industrial uses.
