6804-2RS Water Pump Bearing Thin Section Bearing for Machinery Motors Motorcycles

The 6804 2RS Bearing is a high-performance, single-row deep groove ball bearing designed for applications requiring compact size, precision, and durability. This bearing features double rubber seals (2RS), providing excellent protection against dust, dirt, and moisture while retaining lubrication. With an ABEC 5 precision grade and Z3 clearance, the 6804 2RS bearing ensures smooth operation, low noise, and high rotational accuracy. Its thin-wall design makes it ideal for applications where space and weight are critical, such as in robotics, medical devices, and small machinery.

Key Features:

Double Rubber Seals (2RS): Protects against contamination and retains lubricant for extended performance.
ABEC 5 Precision: Ensures high rotational accuracy and smooth operation.
Z3 Clearance: Provides optimal internal clearance for reduced friction and efficient performance.
Thin-Wall Design: Compact and lightweight, ideal for space-constrained applications.
Durable Construction: Made from high-quality chrome steel for excellent wear resistance.
Low Maintenance: Sealed design reduces the need for frequent relubrication.
Versatility: Suitable for both radial and axial load applications.

Dimensions:

Parameter	Measurement (mm)
Inner Diameter (ID)	20 mm
Outer Diameter (OD)	32 mm
Width (W)	7 mm

Advantages of 6804 2RS Bearing (ABEC 5, Z3 Precision):

High Precision: ABEC 5 precision ensures minimal vibration and noise, making it ideal for precision applications.
Contamination Protection: The double rubber seals (2RS) ensure reliable performance in harsh environments.
Compact and Lightweight: Thin-wall design makes it suitable for applications with space constraints.
Low Friction: Z3 clearance allows for efficient operation, reducing energy consumption and heat generation.
Durability: High-quality materials and construction provide excellent resistance to wear and tear.

Applications:

1. Robotics: Used in robotic joints and small mechanical parts requiring precision and reliability.
2. Medical Devices: Ideal for surgical tools, diagnostic equipment, and other medical instruments.
3. Small Machinery: Suitable for compact machinery and equipment where space is limited.
4. Consumer Electronics: Used in devices like drones, cameras, and small motors.
5. Hobby and DIY Projects: Perfect for small-scale mechanical projects and model building.
6. Automotive: Used in small actuators, sensors, and other automotive components.
