NSK 7217A5TRSULP4Y is a super precision single-row angular contact ball bearing in the 7200 series, 85 mm bore by 150 mm outside diameter by 28 mm width, supplied as a single universally ground unit. Bore Diameter: 85 mm. Outside Diameter: 150 mm. Overall Width: 28 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: 7217.
7217 — 72 dimension series, 85 mm bore.
A5 — 25° contact angle in NSK super precision nomenclature.
TR — phenolic resin cage, outer-ring guided.
SU — single universally ground bearing, flush-ground so any two can be paired DB, DF or DT.
L — light preload class.
P4Y — NSK accuracy grade in the P4 family, commonly quoted as ABEC 7.
Dynamic Load Rating: 129,000 N per bearing. Static Load Rating: 86,500 N per bearing. Limiting Speed: 8,600 rpm grease; 12,800 rpm oil. Permissible axial load Pa: 70.0 kN. Item Weight: 1.79 kg (3.946 lb) per bearing. Cage Material: Phenolic. Cage Type: Outer-ring guided. Preload: Light (L). Lubricant: grease or oil-air, 10 g grease per bearing recommended. Load ratings and mass are stated per bearing.
Effective load centre a: 41.4 mm. Shaft abutment diameter da min: 95 mm. Housing abutment diameter Da max: 140 mm. Housing abutment diameter Db max: 144 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: 1 Pc. Mounting Arrangement: single universal (SU), pairable DB, DF or DT with another SU unit of the same preload class. A preloaded bearing carries a defined preload rather than a running internal clearance.
Matching 25° parts include SKF 7217 ACD/P4A, FAG B7217-E-T-P4S and Fafnir · Timken 3MM9217WI. NSK siblings in the same envelope include 7217A5TYNSULP4 and 7217A5TRDULP4Y, which differ in cage or in arrangement. NTN 7217UCP4 is a comparable 25° super precision bearing rather than a code-for-code match.
