Category: Angular Contact Ball Bearing
Bore: 70 mm
Outer Ø: 110 mm
Width: 20 mm

Overview

IBC 7014.EX Angular Contact Ball Bearing supports combined radial and one-direction axial load through a defined contact angle. It is a high-speed, high-precision choice for pumps, compressors, machine tools, and spindle-related positions where axial rigidity and rotational accuracy matter.

The inner and outer ring raceways are offset to create a contact angle. Single-row, double-row, or matched arrangements can be used to meet axial load direction, preload, and rigidity requirements.

Key features

Supports combined radial and one-direction axial load
High-speed and high-accuracy operation
Preload and rigidity adjustable through matched mounting
Suitable for precision rotating assemblies

Typical applications

Machine tool spindles and support shafts
Pumps and compressors
High-speed motors
Precision gearboxes and robot drives

Selection guidance

Select by contact angle, arrangement, preload, precision class, axial load direction, and operating speed.
