MRC 7216PDTDF angular contact ball bearing set. Bore: 80 mm. Outside diameter: 140 mm. Width: 26 mm per bearing. Series: 7200. Contact angle: 40°. Open on both faces, pressed steel cage, straight bore. Country of origin: United States.
Base number 7216, written on the carton as 7216P, 7216 P DTDF and 7216PDTDF. P: 40° contact angle. DTDF: a tandem pair mounted face-to-face against a single bearing — a three-bearing stack, matched and ground as one set.
A 40° contact angle is the heaviest thrust rating in the angular contact range. The two tandem bearings share thrust in one direction, roughly doubling axial capacity over a single bearing, while the third bearing set face-to-face against them carries thrust the other way. The result is high one-direction thrust capacity together with full reversing capability and good angular rigidity. Face-to-face mounting also accommodates a small amount of misalignment.
Three pieces, supplied as a matched stack: two bearings in tandem, one bearing face-to-face against them. Stack width across all three: 78 mm. Each bearing measures 80 x 140 x 26 mm.
Bearings from a matched stack are kept together and mounted in the marked relationship — the stamped outer ring face of one tandem bearing sits against the unstamped face of the other, and the unmarked outer ring faces meet at the face-to-face joint. Shaft and housing fits are kept light on a controlled-face set, since internal clearance changes the flushness of the ring faces. Face-to-face stacks are axially clamped both in the housing and on the shaft.
The 80 x 140 x 26 mm envelope is shared by SKF 7216 BEP and FAG 7216-B-TVP as related sizes; those are single bearings with different cage materials. Searchable forms: 7216PDTDF, 7216P DTDF, 7216-P-DTDF, 7216 P DTDF, 7216PDT DF.
