NSK 6001 2RS C3 Deep Groove Ball Bearing 12x28x8 mm

Industrial Applications & Use-Cases

The NSK 6001 2RS C3 is a precision-engineered deep-groove ball bearing designed for demanding industrial applications requiring compact dimensions, reliable rotational support and minimal maintenance. With bore diameter 12 mm, outer diameter 28 mm and width 8 mm, this bearing is ideal for small motors, gearboxes, pump drives, automation modules and other machinery where space is limited but performance must not be compromised. The double-sealed (2RS) design protects internal components from contamination and lubricant loss, while the increased internal clearance (C3) enables operation in elevated temperatures or with shaft expansion — aligning with the needs of long-life industrial bearings.

Used either as a standalone bearing or integrated into a bearing unit or bearing housing, this part is optimized for continuity in production lines, maintenance departments and OEM supply chains. Its versatile specification suits retrofit operations as well as new design projects requiring injection-molded housings or compact drive assemblies.

Key Features & Benefits

• Sealed on both sides (2RS) for enhanced protection against dust, moisture and lubricant escape — enabling extended run-time and fewer service interventions.

• Increased clearance “C3”, allowing safe operation under thermal expansion, higher shaft speeds or press-fit scenarios without risk of binding.

• Deep-groove ball design ensures capability to handle both radial and moderate axial loads, delivering smooth motion and low vibration in industrial drives.

• Compact size (12x28x8 mm) makes it specially suited for devices with constrained space — without compromising on run-time or durability.

• High durability and reliability - a hallmark of NSK engineering, offering stable performance and long operational life under industrial conditions.

• Ready to mount - pre-lubricated and sealed, reducing installation time and maintenance requirements in production and service environments.

FAQ - Frequently Asked Questions

1. What does “2RS” indicate in the part designation?
“2RS” means the bearing is sealed with rubber seals on both sides, offering protection from contaminants and lubricant loss and promoting longer service life.

2. What is the significance of the “C3” clearance?
The “C3” internal clearance indicates increased radial internal clearance compared to standard. This benefits applications with thermal expansion, high speed, or press-fit installation, reducing risk of binding or premature failure.

3. Is this bearing suitable for integration into bearing housings or bearing units?
Yes. Thanks to the compact size 12x28x8 mm and seal design, it is suitable for mounting within standard bearing housings or used as a core component of a complete bearing unit in industrial assemblies.

4. What loads can this deep-groove ball bearing handle?
While primarily optimized for radial loads, the deep-groove design also supports moderate axial loads in both directions. It is ideal for many industrial drives, compact gearboxes and machine modules.
