6820-2RS Thin Section Deep Groove Ball Bearing for Agricultural Machinery | 100×125×13 mm

The 6803-ZZ is a high-performance, metric thin-section ball bearing designed to bridge the gap between miniature precision and load-bearing reliability. Featuring dual metal shields (ZZ), this bearing is optimized for high-speed applications where low frictional torque is essential. With a 17mm bore, 26mm outer diameter, and 5mm width, it provides a space-saving solution for engineers looking to reduce the footprint of their rotating assemblies without compromising on rotational accuracy.

The 6801-ZZ is a high-performance, extra-thin section ball bearing designed for precision assemblies where minimizing friction and weight is paramount. Equipped with dual-sided metal shields (ZZ), this bearing excels in high-speed environments by retaining factory-grade lubricant while offering lower rotational torque compared to rubber-sealed alternatives. With a 12mm bore and a compact 21mm outer diameter, the 6801-ZZ is the ideal solution for high-frequency spindles, lightweight drone motors, and sensitive medical instrumentation requiring consistent, low-vibration rotation.

Engineered for applications demanding a minimal spatial footprint without compromising rotational speed, the 6800-ZZ is a premium thin-section deep groove ball bearing. Featuring dual metallic shields (ZZ), it excels in keeping out particulate matter while retaining essential factory lubrication. Because these steel shields do not make physical contact with the inner ring, the 6800-ZZ delivers drastically lower friction and startup torque compared to rubber-sealed variants, making it the premier choice for 10mm bore applications like gimbal systems, high-rpm drone motors, and micro-robotics.

Engineered for micro-mechanical systems, the 688W4ZZ is a specialized miniature ball bearing that combines high-velocity performance with a custom space-saving profile. This specific "W4" variant features a narrower 4mm width compared to standard 688 bearings, making it the ultimate solution for ultra-compact housings. Fitted with double pressed-steel shields (ZZ), it excellently retains premium lubrication while locking out airborne contaminants, ensuring frictionless, low-vibration rotation for sensitive electronics and precision hobbyist gear.

The 618-5ZZ is an ultra-small, precision-engineered ball bearing designed for micro-mechanical assemblies where space is at an absolute premium. Equipped with dual-sided metal shields (ZZ), this bearing is optimized for high-frequency rotation by maintaining internal lubricant integrity while minimizing parasitic drag. With a 5mm bore and a compact 11mm outer diameter, the 618-5ZZ provides the essential stability required for micro-servos, high-speed cooling fans, and sensitive medical sensors that demand nearly silent, low-vibration performance.

The 6802-2RS is a premium metric thin-section deep groove ball bearing manufactured for applications demanding space-saving profiles without compromising load capacity. Unlike metal-shielded variants, this model is equipped with dual contact rubber seals (2RS) that create a tight, highly effective barrier against moisture, dirt, and debris. Measuring 15 mm in bore diameter, 24 mm in outer diameter, and a slim 5 mm in width, the 6802-2RS offers an optimal structural solution for weight-sensitive machinery, bicycle hubs, and electric motors where reliable, maintenance-free operation is mandatory.

The 6818-2RS is a thin-section deep groove ball bearing engineered for applications where space constraints and high radial load capacity must coexist. Featuring dual contact rubber seals (2RS), this bearing provides superior exclusion of moisture, fine dust, and contaminants, making it the preferred choice for environments demanding absolute lubricant retention. With a 90mm bore, 115mm outer diameter, and 13mm width, it is a critical component for heavy-duty industrial gearboxes, precision rotary tables, and large-format electric motors requiring stable operation under consistent loads.

The 6805-2RS is a compact, thin-section deep groove ball bearing engineered for applications demanding high rotational accuracy within tight spatial envelopes. Featuring dual contact rubber seals (2RS), this configuration provides exceptional defense against fine particulate contamination and moisture while ensuring permanent grease retention for maintenance-free operation. With a 25mm bore, 37mm outer diameter, and a slim 7mm width, it serves as a critical component for precision instrumentation, high-speed spindle assemblies, and compact electric drives where reliability and minimal friction are paramount.
