Key Performance Features

01. Superior Contamination Exclusion

The 6820-2RS is equipped with double contact rubber seals made from oil-resistant nitrile rubber. These seals maintain positive contact with the inner ring land, effectively preventing ingress of water, dust, and fine process debris. This sealing configuration significantly extends grease life and protects the precision-ground raceways from abrasive wear, reducing unplanned downtime in demanding applications.

02. Thin-Section Design for Space-Constrained Assemblies

With a width of just 13 mm and a 100 mm bore, this bearing provides a high load-to-space ratio. Its thin-section geometry allows designers to reduce housing width and overall machine footprint while maintaining stable shaft support. This makes the 6820-2RS particularly valuable in modular equipment, robotic systems, and compact industrial machinery.

03. Durable Construction with Pre-Lubrication

Constructed from high-carbon chromium steel (GCr15/SAE 52100), the bearing offers excellent wear resistance and dimensional stability under moderate to heavy loads. The deep raceway grooves ensure smooth rolling of the ball complement, minimizing vibration and noise. The bearing is pre-lubricated with a high-quality lithium-based grease suitable for a wide operating temperature range, eliminating the need for relubrication under normal service conditions.

Design & Configuration

The 6820-2RS is factory-filled with high-quality grease and sealed with contact rubber seals on both sides. This configuration eliminates the need for external relubrication, simplifying maintenance. For applications involving very high speeds, the ZZ (metal shield) variant is recommended due to lower frictional torque. For extreme temperatures or chemically aggressive environments, stainless steel versions or fluorocarbon seals are available upon request. C3 internal clearance options are offered for assemblies where temperature differentials may cause reduced internal clearance.

"Built to withstand harsh operating conditions, the 6820-2RS delivers dependable sealing and consistent performance in a space-saving thin-section package."
