NSK 7214A TY DF P5 super precision angular contact ball bearings, supplied as a face-to-face matched pair. Bore Diameter: 70 mm. Outside Diameter: 125 mm. Overall Width: 24 mm per bearing. Contact Angle: 30°. Precision Class: P5. Cage Type: Ball-guided. Closure Type: Open. Rolling Elements: Ball. Bore Type: Straight. Number Of Rows: 1 per bearing. Series: 7200. Base Number: 7214. Mounting Arrangement: Face-to-face.
7214 — NSK’s number for the ISO 72-series size, 70 x 125 x 24 mm.
A — 30° contact angle.
TY — ball-guided cage.
DF — duplex face-to-face. Two single-row bearings ground as a matched set and mounted with their outer ring front faces together.
P5 — NSK super precision accuracy grade. This series is offered in P5, P4, P4Y and P3.
Dynamic Load Rating: 92,000 N per bearing. Static Load Rating: 59,500 N per bearing. Ratings and mass are per bearing, not per set.
Limiting Speed: 7,700 rpm grease; 10,300 rpm oil. Lubricant: grease or oil.
Item Weight: 1.10 kg (2.425 lb) per bearing.
Permissible axial load Pa: 38,000 N.
A 30° contact angle carries more axial load than the 15° and 25° executions of the same size, at a lower speed ceiling. A face-to-face arrangement sets the two load lines converging inward, which makes the pair more tolerant of shaft and housing misalignment than a back-to-back set.
Shaft abutment diameter da min: 79 mm. Housing abutment diameter Da max: 116 mm. Abutment fillet radius ra max: 1.5 mm.
Bearing chamfer r min: 1.5 mm. Bearing chamfer r1 min: 1 mm. Effective load centre a: 40.1 mm.
Preload classes offered on this size are EL, L, M and H.
Unit Quantity: 2 Pcs. A matched face-to-face duplex pair.
30° bearings of the same 70 x 125 x 24 mm size: Koyo 7214 in standard class, NTN 7214/GNP5 and RHP 7214ATP5, each sold as a single bearing rather than a DF pair. MRC 7214 is the closest MRC execution at its own 29° angle.
