Description

The SKF 6003-2RSC3 Deep Groove Ball Bearing is a versatile and robust component engineered for optimal performance across a wide range of industrial and everyday applications. As a single-row deep groove ball bearing, it features a straightforward design, making it durable, easy to install, and requiring minimal maintenance.

Measuring precisely at 17mm inner diameter, 35mm outer diameter, and 10mm width, this bearing is part of the popular 6000 series, known for its “extra light” design, making it suitable for applications where space is limited. The “2RSC3” designation is crucial for understanding its features:

• 2RS (or 2RSH/2RS1): Indicates that the bearing is equipped with two high-quality rubber seals on both sides. These contact seals are made from oil and wear-resistant synthetic rubber with steel reinforcement, providing superior protection against contaminants like dust and dirt while effectively retaining lubrication. This significantly prolongs the bearing’s service life, making it a reliable choice for demanding environments.
• C3: Denotes an “increased internal clearance” compared to standard bearings. This enhanced clearance allows for thermal expansion and accommodates slight misalignment during operation, which is particularly beneficial in applications experiencing higher temperatures or needing moderate axial movement. The C3 clearance ensures optimal performance and longevity, especially at high rotational speeds, by preventing excessive heat generation.

Common Applications

SKF deep groove ball bearings, including the SKF 6003-2RSC3, are highly versatile and found in a vast array of applications across various industries:

• Industrial Machinery: Electric motors and generators, industrial pumps and fans, material handling equipment (conveyors), gearboxes, and industrial transmissions.
• Agriculture: Farm machinery and equipment.
• Home Appliances: Washing machines, dryers, fans and other consumer electronics.
• Sporting Goods: Skateboards, inline skates, bicycles.
• General Purpose: Instrumentation, agricultural machinery, construction machinery, small engines, and various DIY projects.

Product Variations

The SKF 6003 series offers several variations to suit different application needs. While the 6003-2RSC3 is a popular choice for its sealed design and C3 clearance, you may also encounter:

• SKF 6003: Basic open-type bearing.
• SKF 6003 Z or 6003 ZZ: Shielded bearings with metal shields on one (Z) or both sides (ZZ), offering protection but not as effective as rubber seals against fine contaminants or moisture.
• SKF 6003 C3: Open bearing with C3 internal clearance.
• SKF 6003-2RS1 or 6003-2RSH: Similar to 2RSC3, indicating rubber seals on both sides. The suffix might vary slightly depending on regional standards or specific design updates.
• SKF 6003-ZZC3 (or 6003-2ZC3/6003-2Z/C3): With two metal shields (ZZ/2Z) and C3 clearance. Shields offer protection against larger debris but are not as effective as rubber seals against fine dust or moisture.
