Universal Parts 6300-2RS Sealed Bearing
Expected back in stock: Sep 22, 2026
Description
Restore smooth, quiet wheel and transmission operation with the Universal Parts 6300-2RS dual-sealed deep-groove ball bearing. This is the industry-standard bearing size for small-engine and powersports applications — used in front wheel hubs, GY6 gearboxes, clutch shafts, and more. Pre-lubricated and ready to install. SKU: 105-87.
Mechanic's tip: A grinding sound or play in your wheel is the first sign of bearing failure. Never strike the inner race with a hammer during installation — always use a bearing driver tool or a socket matching the 35mm outer diameter to press it in safely. If one bearing has failed, replace both sides for balanced performance.
Features:
- 2RS dual rubber seals on both sides — locks in grease, locks out moisture, dust, and road grit
- High-carbon chrome steel construction for maximum load capacity and pitting resistance
- ABEC-grade precision balanced for high-RPM operation and reduced parasitic drag
- Pre-lubricated with high-temp grease — ready for immediate installation
