A “one-size-fits-all” bearing selection does not apply universally — especially when it comes to lock reliability and the locking types of mounted bearings. The trend in unit material handling applications has shifted from traditional setscrew locking designs to newer concentric locking solutions. Concentric locking results in more near-perfect concentricity, quieter operation, increased lock reliability, higher speed of operation, and less damage to the shafting. The results: improved equipment performance and increased uptime.
