MR148-2RS Bearings
Couldn't load pickup availability
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.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
