NSK 50BNR10S super precision angular contact ball bearings from the ROBUST ultra-high-speed spindle range, supplied as a universally matched pair. Bore Diameter: 50 mm. Outside Diameter: 80 mm. Overall Width: 16 mm per bearing. Contact Angle: 18°. Precision Class: ABEC 7 / P4Y. Rolling Elements: Ball. Number Of Rows: 1 per bearing. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel.
50 — bore diameter in millimetres.
BNR — NSK ROBUST ultra-high-speed angular contact ball bearing, 18° contact angle.
TYN — polyamide resin cage, ball guided.
DU — universal matching, so the bearings mount back-to-back, face-to-face or in tandem.
EL — extra light preload.
P4Y — special dimensional accuracy with ISO class 4 running accuracy.
Contact Angle: 18°. The shallow angle biases the bearing toward radial stiffness and speed rather than axial capacity, which is why the BNR range is specified for high-dmn machine tool spindles.
Cage Material: Polyamide. Cage Type: Ball-guided. A resin cage is lighter than brass or steel, so cage loads and heat generation stay low at speed.
Preload: Extra light. Lubricant: grease or oil.
Unit Quantity: 2 Pcs. Mounting Arrangement: universal matching.
The 18° contact angle is specific to the NSK BNR range, so bearings from other makers share only the size. The 50 x 80 x 16 mm size is shared with the ISO 7010 bearing, which has a different contact angle and series.
