introduction：5、The gap between the bushing and the shaft The linear expansion coefficient of the self-lubricating block is about steel10times。To adapt to bearing temperature changes，The gap between the shaft and the bushing is matched by the original metal parts（D4／dc4）0.032～0.15mm，Increment to0.45～0.5mm。The self-lubricating block protrudes the bushing metal on one side of the friction pair0.2～0.4mm。This will be fully lubricated during the initial run-in period of bearing operation，Reduce power drag power consumption。
