6003 2RS Sealed Ball Bearing - NECTECH 17x35x10

Applications & Industrial Use

The 6003 2RS bearing is a single-row deep groove ball bearing with double rubber seals (2RS), designed for industrial and mechanical systems requiring reliable rotation under contamination risk. With standard dimensions 17 mm (inner) x 35 mm (outer) x 10 mm (width), this sealed 6003 2RS bearing is widely used in electric motors, gearboxes, pumps, automation systems, conveyors, and various rotating machinery. The robust sealing makes it suitable for harsher environments, reducing maintenance needs and protecting against dust, moisture, and foreign particles.

This model suits many industrial applications where the search term “6003 2RS bearing” is used when customers look for replacement parts or spares. The deep groove ball bearing 6003 2RS design supports primarily radial load and limited axial loads, making it versatile in many usages.

Key Features & Advantages

• Double rubber seals (2RS) on both sides retain lubricant and block contaminants, enhancing longevity in dusty or humid environments.

• Low friction torque and stable rotation performance — ideal for medium to high rotational speeds.

• Standard metric dimensions (17x35x10 mm) enable drop-in replacement in many systems.

• Deep groove ball bearing architecture supports radial loads and moderate axial load capacity.

• Available in various internal clearances (standard, C3, etc.) to accommodate thermal expansion or high-speed needs.

• High durability, corrosion resistance (chromium steel construction), and suitability for industrial automation.

• Meets industry tolerances and design standards, compatible with ABEC classes or ISO equivalents.

According to Koyo’s specifications, the Cr (basic dynamic load rating) is about 7.50 kN, while C0r (basic static load rating) is about 3.25 kN. The limiting speed under grease lubrication is approximately 12,000 rpm.
