Universal Parts CN250 Transmission Needle Bearing

Restore smooth, low-friction power transfer in your CN250 transmission with this Universal Parts replacement needle roller bearing. Designed specifically for the 250cc 4-stroke water-cooled 172mm engine found in Chinese street-legal scooters, ATVs, dune buggies, and go-karts, this is a direct OEM-spec replacement for the factory transmission bearing. Needle roller bearings provide a higher load capacity in a compact form factor compared to standard ball bearings, making them the correct choice for the high-radial-load environment inside the CN250 gearbox.

• OEM-Spec Dimensions: 14mm inner diameter × 22mm outer diameter × 16mm wide — direct drop-in replacement for the factory bearing
• Needle Roller Design: High radial load capacity in a compact form factor — correct bearing type for CN250 172mm transmission shafts
• Steel Construction: Hardened steel outer race and needle rollers for durability under continuous transmission load
• Direct Replacement: Matches OEM specification for compatible CN250 172mm engine transmissions — no modifications required
