Maintaining proper bearing condition is critical on trowel machines where high-RPM rotation and continuous load place sustained stress on rotating components; a degraded bearing left in service will accelerate damage to surrounding shafts, housings, and seals.\u003c\/p\u003e\u003cp\u003eThe 6303 designation refers to a standardized deep-groove ball bearing with a 17mm bore, 47mm outer diameter, and 14mm width, a common precision bearing used in power transmission and motor-adjacent applications. When replacing this bearing, inspect the mating shaft and housing bore for scoring or out-of-round wear before pressing the new bearing into place. Ensure the bearing seats fully and squarely, and check that any associated circlips or retention hardware are properly seated to prevent axial movement under load.\u003c\/p\u003e\u003cp\u003eThis part is compatible with the following Bartell Global walk-behind trowel models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eB446\u003c\/li\u003e\n\u003cli\u003eB446 MEGA-T\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Bartell Global OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Bartell","offers":[{"title":"Default Title","offer_id":43412748402736,"sku":"10203","price":62.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/10203.jpg?v=1784312820","url":"https:\/\/cce-industries.com\/products\/bartell-10203-bearing-6303-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
