Engineered to deliver exceptional rotational stability on standard one-inch shaft applications, the R16-ZZ is a highly versatile inch-series deep groove ball bearing. Designed with twin pressed-steel shields (ZZ), it forms a highly effective barrier against external dirt and particulate matter while securely retaining the factory-filled lubrication. Because these dual metal shields operate without physically touching the inner ring, the R16-ZZ provides a frictionless sealing solution, significantly minimizing startup torque and ensuring cooler running temperatures for electric motors, lawn care equipment, and high-speed rotary assemblies.
