NTN RNA 6916R Needle Roller Bearing
The NTN RNA 6916R is a needle roller bearing designed for use in electrician test equipment. It comes as a single unit in a red finish, supplied in a box. This component suits professionals who need a precise rolling element for maintenance or assembly tasks. It is not intended for buyers seeking a complete tool kit or a powered instrument.
Thermals noise and power
As a passive mechanical bearing, the NTN RNA 6916R generates no heat, noise or electrical draw during normal operation. Its performance depends on proper lubrication and alignment within the host equipment. There are no active cooling requirements or power specifications to consider. Installers should verify fitment before use.
Sustained load behaviour
Under continuous rotational load the bearing maintains smooth motion provided it remains within its design limits and is adequately lubricated. Excessive speed or contamination can accelerate wear over time. The unit carries a three-year parts cover and one-year labour cover from the supplier. Regular inspection helps sustain long-term reliability.

Questions about this item
How do I press the RNA 6916R bearing onto a 90 mm shaft without damaging the needle rollers?
Support the inner ring evenly with a sleeve that matches the 90 mm bore and press straight until the 54 mm wide ring seats fully; never hammer the outer ring or rollers.
What lubrication does the NTN RNA 6916R need during its service life?
Re-grease through the housing port with a compatible roller-bearing grease at intervals dictated by load and temperature; the bearing has no integral seals.
At what point does the 110 mm outer diameter limit heat dissipation under continuous high-speed rotation?
The 110 mm OD restricts surface area for cooling, so sustained speeds near the rated limit raise internal temperature until the grease degrades and clearance drops.
