FAGB7001CB.TP4.DULSuper Precision Spindle Bearing – 12 mm Bore, 28 mm OD, 8 mm Width, 15° Contact Angle, P4 Class, Light Preload, Duplex Universal

Product Description

What this part is:

A FAG/Barden B7001-CB-TP4-DUL super-precision spindle bearing: a single-row angular contact ball bearing, 12 mm bore by 28 mm outside diameter by 8 mm wide, open on both faces, with a 15° contact angle, P4 accuracy and a machined phenolic window cage. It is universally ground to duplex light preload, so pieces of the same designation set against each other directly. Unit Quantity: 1 Pc. One bearing.

Decoding the designation:

B — standard-size steel ball complement.

70 — extra light dimension series.

01 — bore code, 12 mm bore.

C — 15° contact angle.

TP — fabric-base laminate phenolic cage.

P4 — ISO accuracy class 4, equivalent to ABEC 7.

DUL — duplex universal grinding with light preload.

Specifications:

Bearing Type: Single-row super-precision spindle angular contact ball bearing. Contact Angle: 15°. Cage Material: Phenolic. Closure Type: Open. Precision Class: P4 (ABEC 7). Preload: Light. Mounting Arrangement: Duplex Universal, light preload. Reference Speed: 90,000 rpm. Limiting Speed: 60,000 rpm. Dynamic Load Rating: 4.65 kN. Static Load Rating: 1.83 kN. Fatigue Limit Load: 0.188 kN. The phenolic cage is machined from fabric-reinforced laminate and rides on the outer-ring land.

Dimensions and mounting:

Bore Diameter: 12 mm (0.4724 in). Outside Diameter: 28 mm. Overall Width: 8 mm. Bore Type: Straight. Matched sets are assembled from individual pieces of this designation, back-to-back, face-to-face or in tandem, with the preload established by the ground ring faces.

Compatibility and replacement:

Barden is Schaeffler’s super-precision brand, so this bearing carries both the FAG B7001-CB-TP4-DUL designation and the Barden 101-H number on the one carton. Cross-references: Barden 101-H (same bearing under its Barden number); SKF 7001 CD/P4A, NSK 7001CTYNSULP4 and GMN S6001CTA (matching size, 15° angle and P4 class). The FAG HS7001 variant uses a smaller ball complement for higher speed and lower capacity, so it is a related size rather than a substitution.

Frequently asked questions:

What are the dimensions of the FAG B7001-CB-TP4-DUL?

Bore Diameter: 12 mm. Outside Diameter: 28 mm. Overall Width: 8 mm.

What do the contact angle and precision class mean?

C is a 15° contact angle. P4 is ISO accuracy class 4, equivalent to ABEC 7.

Is Barden 101-H the same bearing?

Yes. Barden 101-H is the same bearing under its Barden number.
