The INA ZARF40115-TV-A is a combined needle roller / axial cylindrical roller bearing built for screw-drive and ball-screw support duty, with a 40 mm bore, 115 mm outside diameter and 75 mm overall width. Made in Germany. EAN 4012802417531.
The TV suffix denotes a glass-fibre-reinforced polyamide (PA66) cage; the A suffix is Schaeffler’s increased-accuracy design.
It pairs a single-row radial needle roller assembly with a double-direction axial cylindrical roller assembly in one unit, so a single bearing carries high axial load in both directions plus radial load while holding tight running accuracy.
Radial dynamic: 38 kN
Radial static: 74 kN
Axial dynamic: 117 kN
Axial static: 315 kN
It is designed for screw mounting, giving high rigidity and low settling tendency in machine-tool feed axes and press screw drives.
Note for buyers: the longer ZARF40115-L-TV-A is 93 mm wide, not 75 mm, and is not a dimensional drop-in for this part.
