6012-2RS Rubber Sealed Deep Groove Ball Bearing | Maximum Contamination Protection | 60×95×18 mm

6012-2RS Rubber Sealed Deep Groove Ball Bearing | Maximum Contamination Protection | 60×95×18 mm

The 6012-2RS is a heavy-duty, Double Rubber Sealed Single-Row Deep Groove Ball Bearing built for harsh operating conditions where environmental protection is critical. Engineered with dual contact-type seals (2RS), this bearing creates an airtight barrier that locks in premium lubricant while blocking moisture, dust, and chemical contaminants from entering the raceway. Measuring 60 mm in bore, 95 mm in outer diameter, and 18 mm in width, it falls within the 6000 "Extra Light" ISO series, delivering reliable load support in a slim radial footprint suitable for compact machine designs.

6012-2RS Deep Groove Ball Bearing 60×95×18 mm | ISO 6000 Series – Extra Light | Double Rubber Seals (Contact Type)

Featuring precision-ground raceways and hardened chrome steel rolling elements, the 6012-2RS maintains smooth rotation even when exposed to challenging workplace conditions. The rubber seal configuration provides superior defense against liquid ingress and fine particles compared to metal shield alternatives. Designed to accommodate significant radial forces along with moderate axial loads in both directions, this bearing serves as a dependable solution for equipment operating in outdoor, washdown, or debris-heavy environments.

Key Performance Features

01. Superior Sealing Performance (2RS Design)

The 6012-2RS employs reinforced NBR rubber seals that make direct contact with the inner ring. This contact-type sealing provides exceptional protection against water splashes, mud, and airborne particles, making it ideal for outdoor or wet processing applications where metal shields would fall short.

02. Space-Efficient Profile (6000 Series)

Within the Extra Light series category, the 6012 maintains a reduced cross-sectional height compared to 6200 or 6300 series bearings of identical bore diameter. This allows engineers to design more compact assemblies while retaining adequate load-carrying capability for demanding applications.

03. Sealed-for-Life Lubrication

Each unit is packed with high-grade lithium complex grease during manufacturing. The dual-lip seal construction prevents lubricant migration and contamination ingress throughout the bearing's operational life, eliminating routine maintenance requirements in most installations.

Design & Configuration

The 6012-2RS utilizes synthetic rubber sealing elements reinforced with internal steel cores for structural stability under pressure. Standard production includes CN (Normal) internal clearance, though C3 (Expanded Clearance) versions are recommended for high-temperature motor applications where thermal growth occurs. Users prioritizing maximum rotational speed over sealing performance may consider the metal-shielded (ZZ) variant available through our product range.

"The 6012-2RS stands as the preferred choice for machinery exposed to moisture and contaminants, offering sealed reliability that extends equipment lifespan in the most demanding work environments."
