Product Description

What this part is

NSK 7217C1TDBP4 super-precision angular contact ball bearing, 85 mm bore × 150 mm outside diameter × 28 mm width. Series: 7200. Contact Angle: 15°. Precision Class: P4, ABEC 7. Straight bore, open on both faces. Supplied as a back-to-back matched pair, 2 pieces.

Decoding the designation

Base Number: 7217C, also marked 7217-C on the carton. C: 15° contact angle. DB: back-to-back matched arrangement, 2 bearings. P4: ISO Class 4, ABEC 7. The number is also written 7217-C1-T-DB-P4, 7217 C1 T DB P4 and 7217C1T DB P4.

What these specs mean in practice

A 15° contact angle favours speed and radial stiffness over thrust capacity. A back-to-back pair sets the load lines apart, which carries moment loads and locates a shaft axially in both directions. Basic Dynamic Load Rating: 135 kN per bearing. Basic Static Load Rating: 90.5 kN per bearing. Limiting Speed: 9,500 rpm on grease, 12,000 rpm on oil or oil-air. Mass: 1.79 kg per bearing.

Quantity and configuration

Two bearings, ground and matched as a back-to-back set. Total width of the pair: 56 mm. Matched sets are supplied without a running clearance.

Fitting notes

The pair is fitted as a unit, marked faces together, with the inner rings clamped on the shaft and the outer rings clamped in the housing so the ground offset is held.

Interchange guidance

SKF 7217 CD/P4A covers the same envelope and 15° angle. FAG B7217-C-T-P4S is the Schaeffler cross on the same envelope and angle. A 7217A5 on the same envelope carries a 25° contact angle and is a related size.
