💡 What is the inner ring used for in precision bearings and why is exact bore size important? The inner ring provides the bore interface that mates with the outer ring and rolling elements, ensuring accurate rotation and even load distribution. In practice, that means less downtime and smoother operation. Here's why it matters for maintenance and uptime: - exact bore tolerance helps reduce play and wear - handy replacement for downtime and service costs - compatible with standard bearing geometries for easy cross-reference
