NTN 1R9X12X16 9mm I.D Needle Roller Bearing Roller Bearing

A range of real-time clock products from Maxim incorporating non-volatile RAM memory for data retention. The clock/calendar functions provide seconds, minutes, hours, day, date, month, and year information. The clocks generally operate in either the 12 or 24-hour format with an AM/PM indicator. Additional features may include watchdog timers, alarms and trickle-charging facilities for external back-up batteries; some devices are available which include an integrated crystal for the clock oscillator.

The NTN Inner Ring is a precision-engineered component used in needle roller bearing assemblies. The ring features a finely finished raceway and flattened end faces to ensure smooth operation and reduced friction. Designed without lubrication holes, it’s ideal for applications where external lubrication is managed separately.

Manufactured to ISO Class 0 (RBEC 1) tolerance for consistent performance
