Angular Contact Ball Bearing:7002 AC / 7002 B / 7002 C

Description

Basic Parameters

In the bearing designations 7002 AC / 7002 B / 7002 C, “7” indicates that the bearing type is an angular contact ball bearing. “02” represents the bearing size series (light series with a 02 diameter and width series combination), and “02” indicates that the bearing’s inner diameter is 15 millimeters (calculated as 02 × 5 mm for standard inner diameter coding). As standard parts, their external dimensions (such as outer diameter and width) are typically uniform across the series, though AC, B, and C suffixes denote different contact angles (e.g., AC for 25°, B for 40°, C for 15°).

Product Application

1. Industrial Machinery & Precision Equipment

High-Speed Rotational Systems:

Electric motors, spindle units, and centrifugal pumps (e.g., 7002 C for 15° contact angle, optimized for high speed with moderate axial loads).

Textile machinery, printing presses, and packaging equipment (e.g., 7002 AC for balanced radial-axial load capacity in 25° contact angle).

Heavy-Duty Mechanical Systems:

Rolling mills, metalworking machinery, and industrial gearboxes (e.g., 7002 B for 40° contact angle, designed for heavy axial loads in rugged environments).

2. Transportation & Automotive

Vehicle Components:

Automotive transmissions, wheel hubs, and steering systems (7002 AC or C for compact design and high-speed performance).

Marine propulsion systems and rail vehicle subsystems (occasional use in specialized applications requiring combined load handling).

3. Aerospace & Defense

Aircraft & Aerospace Systems:

Aircraft engine accessories, landing gear mechanisms, and flight control actuators (7002 B preferred for high axial loads in 40° contact angle applications).

Satellite components and precision guidance systems (7002 C for low-friction, high-speed reliability in aerospace environments).

4. Robotics & Automation

Robotic Joints & Actuators:

Industrial robots, collaborative robots (cobots), and robotic arm assemblies (7002 AC or C for precise motion control and moderate load capacity).

Automated Machinery:

Pick-and-place systems, conveyor belts, and sorting equipment (utilizing the bearings’ compact size and dual-load capability).

5. Electronics & Precision Instruments

High-Precision Devices:

Optical telescopes, medical imaging equipment (e.g., MRI machines), and laboratory centrifuges (7002 C for minimal vibration and high-speed stability).

Semiconductor Manufacturing:

Wafer handling systems, lithography machines, and precision positioning stages (requiring contamination-resistant and low-friction bearings like 7002 AC).

6. Retrofitting & Legacy Systems

Classic Machinery Upgrades:

Older industrial equipment or vintage vehicles using historical model equivalents (e.g., retrofitting with 7002 AC for legacy 36102 models, or 7002 B for 46102 models) to maintain compatibility while upgrading performance.
