About this item

  • MR115-2RS — 5x11x4mm, Not 5x11x5mm: 5mm inner bore x 11mm outer diameter x 4mm width. The MR115 is a specific miniature bearing size — confirm your shaft is 5mm, your housing takes 11mm OD, and your bearing pocket is 4mm wide before ordering. Often found in RC car wheel hubs, electric motors, and small hobby gearboxes.
  • Chrome Steel, Pre-Lubricated, Ready to Run: GCr15 chrome steel races and precision balls, factory packed with grease. Double rubber seals (2RS) press against the inner ring on both sides, locking in lubricant and standing up to the dust, dirt, and moisture that come with RC bashing and outdoor hobby use.
  • 20 Bearings — Outfit Your RC Fleet: Traxxas Slash, Rustler, Stampede, Bandit owners know bearings take abuse. With 20 in the pack, you can replace every bearing in the truck with spares left for the next rebuild. Also fits 3D printer motion systems, small electric motors, and hobby servo gearboxes.
  • Smooth, Quiet, Low Friction: Deep groove raceway geometry handles both radial and light axial loads. Precision-ground balls and races produce minimal noise — important when the bearing is spinning inside an RC car at 30,000 RPM or a 3D printer running an overnight print.
  • Match Your Old Bearing Before You Order: Cross-reference MR115-2RS, MR115RS, Traxxas 5116, and any bearing marked 5x11x4mm. Measure your old bearing's bore, OD, and width — if your numbers are 5 x 11 x 4mm, these drop right in. Not sure? The 4mm width (not 5mm) is what sets the MR115 apart from similar sizes.

    I found the replacement parts I needed for my RC truck without having to search through unrelated products. The categories were easy to understand, and the new wheels and suspension parts worked well for my weekend build.

    TinyRacer has a practical selection of RC tools, batteries, and upgrade parts. I picked up several items for maintaining my crawler, and everything made my workbench setup feel much more organized.

    I am still fairly new to RC cars, so I appreciated how clearly the products were grouped. It was easy to compare chargers, connectors, and maintenance supplies for my first off-road vehicle.

    I enjoy upgrading and adjusting my RC vehicles, and TinyRacer makes it convenient to browse parts for different projects. I especially liked the variety of tires, hardware, and drivetrain components available.
