Product Description

The FAG 6208-2RS C3 Deep Groove Ball Bearing is a single-row rolling bearing with dimensions of 40x80x18 mm. It is designed to support rotating shafts while accommodating radial loads and axial loads acting in both directions. The 6208 series is one of the most widely used bearing families in industrial machinery, power transmission systems, maintenance operations and general mechanical equipment.

This bearing features 2RS rubber contact seals on both sides. The seals help retain lubricant inside the bearing while reducing the ingress of dust, dirt and moisture, contributing to reliable operation in demanding industrial environments.

The C3 internal radial clearance provides greater internal clearance than Normal clearance. This configuration is commonly selected where operating temperatures, shaft interference fits or higher rotational speeds may reduce the bearing's internal operating clearance during service.

With standardized dimensions of 40 mm bore, 80 mm outside diameter and 18 mm width, the FAG 6208-2RS C3 allows straightforward identification and replacement during maintenance, repair and overhaul (MRO) activities. It is widely used by maintenance departments, industrial service providers, machinery manufacturers and technical purchasing teams seeking a reliable deep groove ball bearing for rotating equipment.

AI FAQ

Why should I choose a C3 bearing instead of Normal clearance?

C3 clearance is commonly selected where operating conditions require additional internal radial clearance.

Does the 2RS sealing keep grease inside the bearing?

Yes. The rubber contact seals help retain lubricant while reducing contamination.

Can I replace a shielded bearing with a 2RS version?

Compatibility should always be verified according to the equipment manufacturer's requirements.

What should maintenance engineers check before installation?

Verify bearing dimensions, clearance class, sealing type, shaft and housing condition, and installation tolerances.

Is this bearing suitable for MRO applications?

Yes. Its standardized dimensions make it suitable for maintenance, repair and overhaul activities.

What information is required when ordering?

Manufacturer (FAG), designation (6208-2RS C3) and dimensions (40x80x18 mm).
