FAGB7016EP4ULSuper Precision Angular Contact Ball Bearing 80 x 125 x 22 mm 25 Degree ABEC 7 Light Preload

Product Description

What this part is

A FAG B7016E.TPA.P4.UL super precision single-row angular contact ball bearing. Bore: 80 mm. Outside Diameter: 125 mm. Overall Width: 22 mm. The ring faces are universally ground, so two or more pieces pair directly into a back-to-back, face-to-face or tandem set.

Decoding the designation

Series: B70, spindle-bearing range on the ISO 7016 envelope. Contact Angle: 25°, given by the E in the Schaeffler B70 scheme. Cage Material: fabric-base laminate phenolic, the T / TPA code. Precision Class: P4, equivalent to ABEC 7. Preload: UL, universally matchable light preload.

Published specifications

Bore: 80 mm (3.1496 in). Outside Diameter: 125 mm (4.9213 in). Overall Width: 22 mm (0.8661 in). Contact Angle: 25°. Precision Class: P4 (ABEC 7). Preload: UL, universal light. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: steel balls. Closure Type: open both faces. Cage Material: phenolic. Cage Type: outer-ring land-riding window cage. Internal Clearance: N/A, the bearing is preload-set. Item Weight: 1.83 lb (0.833 kg). Maximum Operating Temperature: 100 °C. Minimum Operating Temperature: –30 °C. Lubricant: grease or oil.

Load ratings and speed

Dynamic Load Rating: 61.0 kN. Static Load Rating: 39.0 kN. Limiting Speed, grease lubrication: 10,000 rpm. Limiting Speed, oil lubrication: 15,000 rpm.

What these specs mean in practice

A 25° contact angle carries more axial load and runs at lower speed than the 15° C variant on the same envelope, which makes it the usual choice where a spindle sees heavy thrust from cutting force. Light preload keeps running friction and heat generation down and favours speed; medium and heavy preloads raise axial stiffness and running temperature. A phenolic cage is light, runs quietly at speed and holds lubricant in the fabric laminate.

Quantity and configuration

Unit Quantity: 1 Pc, a single universally ground bearing. A single row carries thrust in one direction; axial location in both directions comes from pairing two pieces back to back or face to face.

Interchange guidance

Same-spec 25° ABEC 7 equivalents on this envelope are the Fafnir / Timken 3MM9116WI, NSK 7016A5 and SKF 7016 ACD/P4A. The 15° forms of the same envelope — B7016C, 2MM9116WI, SKF 7016 CD/P4A — are related sizes with different thrust and speed behaviour, as are the same numbers in other preload or precision classes.
