Namura's bearings are manufactured from SCM415 Chromoly Steel and treated using a process called carbonnitriding; this enhances the fatigue strength and heat dissipating capacity of the cage. The overall bearing structure and high rigidity allows them to withstand the significant stress levels created by varying\/high RPMs and the impact of an engine's stroke. Another key feature that our bearing assemblies have is a silver coated cage. Yes, the cage that holds our needle bearings is electroplated first with copper and then a second coating of silver to better resist the erosive materials it is exposed to. This coating also decreases the friction between the cage and the bearings allowing for longer assembly life and increased reliability..\u003cbr\u003e\u003cbr\u003eVehicle Fitment:\u003cbr\u003e\u003cbr\u003e1998-1999 Sea-Doo GSX Limited\u003cbr\u003e 2000-2002 Sea-Doo GTX\u003cbr\u003e 2001-2003 Sea-Doo GTX DI\u003cbr\u003e 1998-1999 Sea-Doo GTX Limited\u003cbr\u003e 2000-2001 Sea-Doo LRV\u003cbr\u003e 2000-2002 Sea-Doo RX\u003cbr\u003e 2001-2003 Sea-Doo RX DI\u003cbr\u003e 2003-2004 Sea-Doo XP DI\u003cbr\u003e 1998-1999 Sea-Doo XP Limited","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44218680344698,"sku":"8829306","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/947170d5f9d34044ab593d3f4637a538_2c788f1a-c6ab-4730-978a-f6f9f6f9cef4.jpg?v=1791053521","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-09-b081-1-wrist-pin-bearing-21-x-25-x-23-8mm","provider":"Powersport Superstore","version":"1.0","type":"link"}
