6902-ZZ Bearing Product Overview & Core Advantages
The 6902-ZZ is a single row deep groove ball bearing designed for high performance in a compact form factor. Engineered for primarily radial loads, it offers reliable operation and is characterized by its shielded (ZZ) construction, which provides effective contamination protection. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures consistent quality and is ideal for applications demanding high rotational speeds and long-term reliability without the need for relubrication.
6902-ZZ Bearing Model Code Explained, Specifications & Naming Convention
- 6902: Basic model number indicating a single row deep groove ball bearing with a 15mm bore and 28mm outside diameter.
- ZZ: Denotes that the bearing is equipped with non-contact steel shields on both sides. This provides effective protection against contaminants while maintaining a low torque and allowing for high limiting speeds.
6902-ZZ Bearing Structural Features & Performance Benefits
The single row deep groove ball bearing design of the 6902-ZZ features a continuous raceway on both inner and outer rings, enabling it to handle not only significant radial loads but also moderate axial loads in both directions. The use of chrome steel for all critical components (rings, balls, cage) ensures high strength, durability, and resistance to wear. The shielded (ZZ) design protects the internal components from dust and debris, contributing to a long service life and maintenance-free operation. With a limiting speed of 29,000 rpm, it is engineered for high-speed applications.
6902-ZZ Bearing Typical Application Areas
The 6902-ZZ is widely used in various precision machinery and equipment, including:
- Electric Motors
- Small Gearboxes
- Office Automation Equipment
- Medical Devices
- Computer Cooling Fans
- Precision Instruments
