NTN RNA 6919R Needle Roller Bearing
The NTN RNA 6919R is a needle roller bearing supplied by ZIBOO for electrician tool applications. It comes as a single unit in a box with a red finish. The bearing measures 110 by 130 by 63 millimetres. It carries a three-year parts and one-year labour guarantee.
Sustained load behaviour
Needle roller bearings distribute load across many small rollers, reducing stress concentrations during continuous operation. The 63 millimetre width provides a broad contact surface that helps maintain consistent performance under prolonged radial forces. Heat buildup is managed through the large rolling element count. Proper lubrication intervals remain essential for long service life.
Dimensional and interface limits
The bearing fits shafts of 110 millimetres and housings of 130 millimetres with a 63 millimetre width. These fixed dimensions determine interchangeability with other RNA 6919R units. Installation requires precise machining tolerances on both shaft and bore. Axial displacement is not accommodated by this design. Buyers needing integrated seals or alternative width options must select a different bearing series.

Questions about this item
Does the NTN RNA 6919R needle roller bearing generate noticeable heat or noise during continuous operation?
The NTN RNA 6919R is a passive mechanical component with no moving electrical parts, so it produces no operational noise or heat itself; any temperature rise comes from the surrounding machinery it supports.
What shaft and housing dimensions must my equipment have to install the NTN RNA 6919R correctly?
The bearing requires a shaft diameter of 110 mm and a housing bore of 130 mm, with a bearing width of 63 mm, matching the RNA 6919R specification.
Can the NTN RNA 6919R replace an older bearing with different width but the same 110 mm inner and 130 mm outer diameters?
No, the 63 mm width is fixed; a different width would change the axial location and load distribution, so the replacement must match all three dimensions exactly.
