You can rely on NSK

NSK claims its Molded Oil bearings can cut maintenance and are more reliable.

Bearing lubricant tends to be flushed out under repeated washdowns, leading to premature bearings failure. NSK's molded oil bearings are made of a plastic composite material with more than 50% lubricating oil impregnated in the bearing and are designed as a replacement for traditional bearings.

Machines fitted with molded oil bearings can save money according to NSK, because they reduce the downtime associated with relubrication intervals and the costs of replacement bearings and lubricants.
