6003 2RS C3 SNR Sealed Ball Bearing 17x35x10

Applications & Industrial Use

The 6003 2RS C3 SNR is a single-row deep groove ball bearing with dual rubber seals (2RS) and increased internal clearance (C3). Its dimensions 17 mm x 35 mm x 10 mm make it a standard choice in many industrial and mechanical systems. The extra internal clearance (C3) is beneficial in environments with thermal variation, enabling the bearing to accommodate slight radial expansion without binding.

This sealed version — often searched as “sealed 6003 2RS C3” — is ideal for use in motor housings, gearboxes, pumps, conveyor drives, automation systems, and other rotating machinery where dust, moisture, or contamination are concerns. Engineers and buyers frequently search for the full specification “6003 2RS C3 17x35x10 bearing” when sourcing replacements or spares.

Key Features & Advantages

• Dual rubber seals (2RS) on both sides retain lubrication and prevent ingress of particles, enhancing reliability and operational lifetime.

• Internal clearance C3 provides extra radial play versus standard clearance, allowing for thermal expansion and reducing the risk of seizure in hotter conditions.

• Deep groove ball bearing design supports radial loads and limited axial loads — a versatile solution for many mechanical assemblies.

• Standard metric dimensions (17x35x10 mm) ensure compatibility with many existing housings and shafts.

• Low friction moment and stable performance increase efficiency and reduce heat generation.

• Material: hardened chrome steel (bearing steel) — excellent in terms of wear resistance and fatigue life.

• Suitable for industrial, automation, HVAC, and mechanical drive applications.

• Compatible with global standards and interchangeable with high-quality brands (SKF, NSK, etc.), increasing trust in the “6003 2RS C3 SNR” designation.

According to Timken’s catalog, the 6003-2RS-C3 bearing is offered as a deep groove ball bearing with super-finished raceways and controlled geometry, confirming the standard nature of its design.
Motion’s catalog similarly describes the 6003-2RS C3 as a 17 mm bore, 35 mm OD, 10 mm width double sealed bearing with internal clearance C3.
