Product Description

What this part is

FAG B7006C.TPA.P4S.UL single-row angular contact spindle bearing, carton designation B7006 C TPA P4 K5 UL. Bore: 30 mm. Outside Diameter: 55 mm. Overall Width: 13 mm. Number Of Rows: 1. Rolling Elements: Ball, 20 balls of 4.762 mm diameter. Bore Type: Straight. Closure Type: Open. Bearing Material: chrome steel rings and chrome steel balls. Series: B70, ISO dimension series 10. Item Weight: 0.113 kg (0.25 lb).

Decoding the designation

Contact Angle: 15°, from the C code on a B70 designation. Cage Material: fabric-base laminate phenolic. Cage Type: machined, outer-ring guided. Precision Class: P4, equivalent to ABEC 7 and ISO Class 4. Preload: light, from the UL code. Mounting Arrangement: universal. Searchable forms of the number: B7006C.TPA.P4S.UL, B7006CTPAP4K5UL, B-7006-C-TPA-P4-K5-UL, B7006 C TPA P4 K5 UL, 7006C.

Load ratings and speed

Dynamic Load Rating: 14.4 kN (3,237 lbf). Static Load Rating: 6.7 kN (1,506 lbf). Fatigue Load Limit: 0.69 kN. Reference Speed: 43,000 rev/min. Limiting Speed: 28,000 rev/min. Operating Temperature Range: −30 °C to 100 °C.

What these specs mean in practice

The C execution of the B70 range uses a 15° contact angle: high speed, high radial rigidity, modest thrust capacity. The E execution’s 25° reverses both. Inside a 55 mm outside diameter this bearing runs 20 balls of 4.762 mm, which is what sets a 14.4 kN dynamic rating on so slender a section. Light preload keeps rolling contact true at 28,000 rev/min without the heat a medium or heavy setting adds. The fabric-base laminate phenolic cage is machined and guided on the outer ring land, so a stationary surface steadies it at speed; its low mass and self-lubricating character keep cage friction down, and it sets the 100 °C ceiling.

Quantity and configuration

Unit Quantity: 1 Pc. Internal Clearance: N/A. The UL code makes this a preload-set bearing rather than a clearance-set one, so no radial clearance class applies. Universal grinding means any two of these clamp together back-to-back or face-to-face at the rated light preload with no custom spacer, and share load equally in tandem.

Interchange guidance

Carton designation carried on this part: 2MM9106WI CR SUL, the Fafnir equivalent, whose 2MM prefix independently confirms the 15° angle. Same-envelope 15° super-precision executions in other schemes: SKF 7006 CD/P4A, NSK 7006CTRSUL, RHP 7006CTSULP4 and GMN S6006CTA. The FAG B7006C.TPA.P4.UL is a separate part number in the same size. A B7006-E execution carries a 25° contact angle in this envelope, which makes it a related size rather than a substitution.
