By using military level, high precision HRC-64 hardended Grade 5 Chromium Steel Balls, and 52100 High-Carbon Chromium-Alloy mirror polished races. This combination allows Enduro's ABEC 5 bearings to use tolerances twice as tight as ABEC 3, and operate without any noise. The Graphite\/Nylon ball retainers allow virtually frictionless movement and provide constant lubrication to maximise the life of the bearing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBearing Code: 6903 (61903\/29.5)\u003c\/li\u003e\n\u003cli\u003eDimensions: 17mm x 29.5mm x 7mm\u003c\/li\u003e\n\u003cli\u003eABEC: 5\u003c\/li\u003e\n\u003cli\u003eGrade: 5\u003c\/li\u003e\n\u003cli\u003eSeals: SRS\u003c\/li\u003e\n\u003cli\u003eGrease: Kyodo Yushi PS-2\u003c\/li\u003e\n\u003cli\u003eApplication: Hubs, Bottom Brackets\u003c\/li\u003e\n\u003cli\u003eWeight: 15.03g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Enduro Bearings","offers":[{"title":"Default Title","offer_id":45335959175325,"sku":"EB8448","price":11.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/9434\/1977\/files\/4b5380f7-e7f9-4a07-96e9-6f28e3f0f403.jpg?v=1731020814","url":"https:\/\/www.bikeparts.co.uk\/products\/enduro-bearings-61903-29-5-srs-abec-5-7mm","provider":"BikeParts.co.uk","version":"1.0","type":"link"}
