The 6800 Series bearings stand out as a premier line of thin-section deep-groove ball bearings, engineered to deliver exceptional performance in scenarios where space efficiency, lightweight design, and high rotational speed capabilities are non-negotiable. As a staple in industrial and commercial bearing solutions, this series is celebrated for its optimized structure that minimizes radial space requirements—making it an ideal choice for compact machinery and equipment where every millimeter of space counts.
Standardized Dimensions & Specifications
The 6800 Series bearings are benchmark for thin-section deep-groove ball bearings with standardized dimensions: 10 mm inner diameter, 19 mm outer diameter, and 5 mm width. This base model serves as the foundation for the series’ variants, each differentiated by suffixes that indicate specific sealing or shielding configurations—tailored to meet the unique environmental and maintenance needs of diverse applications.
Configuration Variants
Open-Type Design
Designed for applications prioritizing minimal friction and maximum rotational speed. Without seals or shields, they offer unimpeded performance but require external protection systems and regular lubrication—ideal for controlled environments like precision machine tool spindles.
Shielded Variants
Featuring non-contact metal shields that effectively block dust and dirt while preserving low friction. These are perfectly suited for hand tools, flushing valves, and small agricultural machinery components.
Sealed Series
Equipped with dual contact rubber seals for superior protection against moisture, chemicals, and abrasive particles. These are maintenance-free for the majority of their service life.
Industry Applications
The compact design and reliable performance of 6800 Series bearings have made them a preferred choice across specialized fields:
Medical & Precision: Anesthesia machines, chromatography accessories, and precision spindles where sterility is paramount.
Versatile Engineering: Capable of accommodating both radial and axial loads across a wide range of operating temperatures.
Whether integrated into industrial machine tools, commercial automotive components, or medical equipment, these bearings consistently deliver the durability, efficiency, and space-saving design that modern applications demand—solidifying their reputation as a trusted solution for engineers and procurement professionals worldwide.
