NSK 7018A5TYDULPA7 super-precision angular contact ball bearing, 90 mm bore × 140 mm outside diameter × 24 mm width. Series: 7000, bore code 18. Contact Angle: 25°. Preload: light. Straight bore, open on both faces.
Base Number: 7018A5. A5: 25° contact angle. TY: ball-guided cage. DUL: duplex universally ground set at light preload. The number is also written 7018-A5-TY-DUL-PA7, 7018 A5 TY DUL PA7 and 7018A5TYDUL PA7. Fafnir 3MM9118WI covers the same bearing in the Fafnir scheme.
A 25° contact angle carries more thrust and less speed than a 15° bearing on the same envelope. Basic Dynamic Load Rating: 85.5 kN. Basic Static Load Rating: 65.5 kN. Limiting Speed: 8,500 rpm on grease, 12,000 rpm on oil or oil-air. Mass: 1.17 kg per bearing.
Ground as a universally matchable duplex set at light preload, which mounts back-to-back, face-to-face or in tandem from the same pair of rings. Total width of a pair: 48 mm. Preloaded sets are supplied without a running clearance.
The set is fitted as a unit with the marked faces together, inner rings clamped on the shaft and outer rings clamped in the housing so the ground offset holds the preload.
SKF 7018 ACD/P4A DGA is a same-envelope 25° universally matchable set at light preload. Fafnir 3MM9118WI is the same 25° bearing in the Fafnir 9100WI scheme. FAG B7018-E-T-P4S covers the same envelope and angle with a phenolic cage, so it is a related size. Fafnir 2MM9118WI carries a 15° contact angle and is a related size.
