P4 6800 Series Bearing C2 C0 C3 C4 Robot Arm Bearing Standard Size

Standard Size Deep Groove Ball Bearing 6800 For Robot Arms

The 6800 Series Bearing is a high-precision, miniature deep groove ball bearing designed for applications requiring exceptional accuracy and reliability, such as robot arms. With a P4 precision grade, this bearing ensures ultra-smooth operation, minimal vibration, and high rotational accuracy. It is available in multiple internal clearance options (C2, C0, C3, C4), allowing it to be tailored to specific operational needs, such as high-speed performance or thermal expansion management. The compact size and high precision of the 6800 series make it an ideal choice for robotics, automation, and other precision machinery.

Key Features:

P4 Precision Grade: Ensures ultra-smooth operation, low noise, and high rotational accuracy.
Multiple Clearance Options (C2, C0, C3, C4): Allows customization for specific applications, such as high-speed or high-temperature environments.
Compact and Lightweight: Miniature design ideal for applications with space constraints.
High-Speed Capability: Designed for efficient operation at high rotational speeds.
Durable Construction: Made from high-quality chrome steel for excellent wear resistance.
Versatility: Suitable for both radial and axial load applications.

Dimensions (Standard Size):

Parameter	Measurement (mm)
Inner Diameter (ID)	10 mm
Outer Diameter (OD)	19 mm
Width (W)	5 mm

Internal Clearance Options:

C2 Clearance: Tighter than normal, suitable for applications requiring high precision and low vibration.
C0 Clearance: Standard clearance, ideal for general-purpose applications.
C3 Clearance: Larger than standard, suitable for high-speed or high-temperature environments.
C4 Clearance: Even larger clearance, designed for applications with significant thermal expansion.

Advantages of 6800 Series Bearing (P4 Precision):

Ultra-High Precision: P4 precision grade ensures minimal vibration and noise, making it ideal for robotics and automation.
Customizable Clearance: Multiple clearance options allow for optimization based on specific operational needs.
Compact Design: Perfect for applications with limited space, such as robot arms and small machinery.
High-Speed Performance: Designed for smooth operation at high rotational speeds.
Durability: High-quality materials and construction provide excellent resistance to wear and tear.

Applications:

Robot Arms: Used in robotic joints and manipulators for precise and smooth movement.
Automation Equipment: Ideal for CNC machines, pick-and-place systems, and other automated machinery.
Medical Devices: Suitable for precision instruments like surgical robots and diagnostic equipment.
Aerospace: Used in small actuators and control systems requiring high precision.
Optical Equipment: Ensures smooth operation in cameras, lenses, and other optical devices.
Hobby and DIY Projects: Perfect for small-scale mechanical projects and model building.
