Product Description

What this part is

IBC B7009-E super-precision single-row angular contact ball bearing, the 7009 / 71909 spindle size. Bore Diameter: 45 mm. Outside Diameter: 75 mm. Overall Width: 16 mm. Contact Angle: 25°. Number Of Rows: 1. Cage Material: Textile-laminate phenolic. Cage Type: Outer-ring guided. Precision Class: ISO P4 / ABEC 7. Preload: Light, universally ground. Closure Type: Open. Unit Quantity: 1 Pc.

Decoding the designation

B7009 — super-precision single-row angular contact ball bearing, 45 x 75 x 16 mm. The B prefix marks the spindle-bearing range.

E — 25° contact angle.

TPA — textile-laminate phenolic cage, outer-ring guided.

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

UL — universal, light preload. The faces are ground so that any two bearings of this designation clamp up to a defined light preload in back-to-back, face-to-face or tandem arrangement.

What these specs mean in practice

A 25° contact angle gives more thrust capacity and axial stiffness than 15°, and more speed capability with less heat than 40°. Universal grinding gives a repeatable light preload without shims. The textile-laminate phenolic cage is light, quiet and self-lubricating. P4 / ABEC 7 controls bore, outside diameter, width and radial and axial runout.

Quantity and configuration

Unit Quantity: 1 Pc. Single universally ground bearing; two bearings of this designation form a light-preload pair.
