MR148-2RS Bearings

Pack of 10 MR148-2RS miniature ball bearings for compact motion builds. These are 8 mm ID × 14 mm OD × 4 mm wide deep-groove radial bearings with rubber seals on both sides, sized for BOMs that call out MR148-2RS / MR148RS.

Why use the 2RS sealed version?

• Double rubber seals help keep dust and debris out while retaining grease inside the bearing.
• 8x14x4 mm metric size fits compact idlers, small rollers, robotics, RC, and 3D-printer motion assemblies where a thin 8 mm-bore bearing is specified.
• Ready-to-install pack of 10 gives you enough bearings for spares, rebuilds, or multi-bearing printed mechanisms.

Specifications

• Bearing code: MR148-2RS / MR148RS
• Type: miniature deep-groove radial ball bearing
• Inner diameter: 8 mm
• Outer diameter: 14 mm
• Width: 4 mm
• Closure: rubber sealed on both sides (2RS)
• Quantity: 10 bearings

Fitment notes

• Use these when your BOM, mod, or printed part specifically calls for MR148-2RS, MR148RS, or an 8x14x4 mm sealed bearing.
• This is a non-flanged bearing. If your design needs a flange, check the called-out part number rather than substituting by bore size alone.
• Not a substitute for 608, 688, 695, 623, or F-series flanged bearings; those are different outside diameters, widths, or flange geometries.

Need a different bearing size? We also stock MR95-2RS bearings, 623-2RS bearings, F695-2RS flanged bearings, and other small motion hardware.
