FAQ

Q1: What are the dimensions of this bearing?
A: This ball bearing has a 1/2" inner diameter (ID) and a 1-1/8” outer diameter (OD), designed for kart and lawnmower spindle king pins.


Q2: Why is there little to no grease inside the bearing?
A: These bearings are intended for racing use and come with minimal or no grease to reduce rolling resistance. This ensures freer spinning for optimal performance.


Q3: How should I maintain this bearing?
A: We recommend applying light oil before each race day to maintain smooth operation and prevent wear without adding excessive drag.


Q4: Can I use this for general-purpose applications?
A: While these bearings are optimized for racing, they can also be used in other low-friction, precision front-end setups where minimal resistance is required.


Q5: Do the bearings come pre-lubricated?
A: Most units include low-contact seals and minimal factory grease. It's best to inspect and oil them before installation or racing.
