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.\u003c\/li\u003e\n\u003cli\u003eChrome 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.\u003c\/li\u003e\n\u003cli\u003e20 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.\u003c\/li\u003e\n\u003cli\u003eSmooth, 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.\u003c\/li\u003e\n\u003cli\u003eMatch 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.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Donepart\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight:\u003c\/strong\u003e 5 Grams\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Number:\u003c\/strong\u003e MR115 2RS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Thickness:\u003c\/strong\u003e 4 Millimeters\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Donepart","offers":[{"title":"Default Title","offer_id":52024018501920,"sku":"B0D6FL2YRN-size-mr115-2rs","price":31.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/7682\/9472\/files\/51mBN5LoRzL.jpg?v=1784806705","url":"https:\/\/tinyracer.com\/products\/mr115-2rs-miniature-ball-bearings-5x11x4mm-20-pack-double-rubber-sealed-chrome-steel-pre-lubricated-for-rc-cars-traxxas-slash-electric-motors-hobby-projects-size-mr115-2rs","provider":"TinyRacer","version":"1.0","type":"link"}
