NSK 7218A5TRDULP4Y is a super precision single-row angular contact ball bearing in the 7200 series, 90 mm bore by 160 mm outside diameter by 30 mm width, supplied as a universally ground pair. Bore Diameter: 90 mm. Outside Diameter: 160 mm. Overall Width: 30 mm. Contact Angle: 25°. Precision Class: ABEC 7 / P4. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Number Of Rows: Single Row. Bearing Material: Bearing Steel. Series: 7200 Series Super Precision. Base Number: 7218.
7218 — 72 dimension series, 90 mm bore.
A5 — 25° contact angle in NSK super precision nomenclature.
TR — phenolic resin cage, outer-ring guided.
DU — universally ground duplex set, flush-ground so the two rings pair back-to-back, face-to-face or in tandem.
L — light preload class.
P4Y — NSK accuracy grade in the P4 family, commonly quoted as ABEC 7.
Dynamic Load Rating: 147,000 N per bearing. Static Load Rating: 100,000 N per bearing. Limiting Speed: 8,000 rpm grease; 12,000 rpm oil. Permissible axial load Pa: 83.5 kN. Item Weight: 2.31 kg (5.093 lb) per bearing. Cage Material: Phenolic. Cage Type: Outer-ring guided. Preload: Light (L). Lubricant: grease or oil-air, 12 g grease per bearing recommended. Load ratings and mass are stated per bearing, not per set.
Effective load centre a: 44.1 mm. Shaft abutment diameter da min: 100 mm. Housing abutment diameter Da max: 150 mm. Housing abutment diameter Db max: 154 mm. Shaft fillet radius ra max: 2 mm. Housing fillet radius rb max: 1 mm. Chamfer r min: 2 mm. Chamfer r1 min: 1 mm.
Unit Quantity: 2 Pcs. Mounting Arrangement: universal duplex (DU), pairable DB, DF or DT. A preloaded set carries a defined preload rather than a running internal clearance.
Equivalents at 25° include SKF 7218 ACD/P4A, FAG B7218-E-T-P4S and Fafnir · Timken 3MM9218WI. NSK siblings in the same envelope include 7218A5TYNDULP4 and 7218A5TRSULP4Y, which differ in cage or in arrangement. NTN 7218UCDBP4 is a comparable 25° super precision bearing rather than a code-for-code match.
