6800 Series Bearings
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.
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.
The open-type 6800 Series bearings are 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 to safeguard against contaminants—ideal for controlled environments like precision machine tool spindles where lubrication is closely managed. Shielded variants feature non-contact metal shields that effectively block dust, dirt, and other particulate debris while preserving the series’ signature low friction and high-speed performance. These are particularly well-suited for hand tools, flushing valves, and small agricultural machinery components where moderate environmental protection is needed without compromising operational efficiency.
Sealed 6800 Series bearings are equipped with dual contact rubber seals, providing superior protection against moisture, chemicals, and abrasive particles while retaining pre-applied lubricant. This makes them maintenance-free for the majority of their service life, a critical advantage in harsh or hard-to-access applications such as sewage treatment equipment, electro-hydraulic lifting platform mechanisms, and automotive lamp adjusters. Additionally, their compact design and reliable performance have made them a preferred choice in specialized equipment like anesthesia machines and chromatography accessories, where precision and sterility are paramount.
Engineered to accommodate both radial and axial loads, 6800 Series thin-section deep-groove ball bearings excel in a wide range of operating temperatures, further enhancing their versatility across industries. 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.
