6905-2RS Low-Contact Sealed Kart Wheel Bearing 25×42×9 mm
Sealed version of the OTT 6905 kart wheel bearing and a common OEM fitment on many kart brands. Its low-contact rubber seals keep grease in and dirt, dust and water out without the drag of traditional full-contact seals, so the wheel still rolls freely. Races and balls are carbon-nitrided bearing steel for wear and pitting resistance. Also available as a hybrid ceramic bearing with Japanese-made silicon nitride (Si₃N₄) balls, which lowers rolling-element weight, friction and heat build-up.
