6802 Bearing | Open / ZZ / RS Seals | Durable Materials And Practical Industrial Uses

6802 bearing is a lightweight thin-section deep groove ball bearing engineered for compact mechanical assemblies. It stands out for steady low-torque operation, minimal vibration and reliable rotational stability under variable load conditions. With three practical sealing structures and multi-type metal material options, this versatile bearing caters to diverse commercial, precision and corrosive working environments for miniature mechanical systems.

6802 Bearing Seal Structure Overview

6802 Open Bearing: Adopts uncovered open-frame structure with unobstructed air circulation, delivering excellent heat dissipation and ultra-low running resistance. It supports continuous high-speed rotation and convenient on-site lubrication refilling. Suited for clean, dry indoor working environments, widely used in precision testing equipment, miniature rotary mechanisms and high-speed electronic transmission modules.

6802ZZ Bearing (Double Metal Shields): Features dual-sided non-contact metal shielding plates, effectively blocking dry dust, fine particulate impurities and floating debris. This non-blocking design creates no extra operating resistance, ensuring stable high-speed rotation and good heat resistance. Ideal for dry working scenarios such as small drive motors, precision gauges and intelligent office automation devices.

6802RS Bearing (Double Rubber Seals): Equipped with dual lip contact rubber seals, achieving tight isolation against moisture, splashed water, dust and dirt. It delivers outstanding environmental tolerance and long-term maintenance-free performance, perfectly applicable to humid, dusty and complex working conditions including smart wearable devices, outdoor miniature machinery and automated sensing equipment.
