SKF 6215 NR Deep Groove Ball Bearing - 75x130x25 mm

Industrial Applications of SKF 6215 NR Bearing

The SKF 6215 NR is a single-row deep groove ball bearing with dimensions 75 mm (bore) x 130 mm (outer diameter) x 25 mm (width).
The “NR” suffix indicates a snap ring groove and retaining ring, allowing easy and secure axial location in bearing housings or bearing units. This feature is particularly valuable in industrial drive systems, electric motors, gearboxes, pumps, and conveyors, where high reliability and stable operation are essential.

SKF bearings are known for their precision engineering, minimal friction, and extended service life, making this model ideal for continuous-duty applications in manufacturing, automation, and power transmission systems.

Key Technical Advantages and Performance Benefits

• Deep groove design (single row) - supports radial and moderate axial loads while maintaining smooth, low-noise operation.

• NR version (snap ring groove) - enables secure axial positioning and simplifies bearing assembly in housings and units.

• Standard dimensions (75x130x25 mm) - ensures full interchangeability with industry-standard housings and replacement parts.

• High durability and precision - made of premium SKF bearing steel with advanced heat treatment for long operational life.

• Reliable operation under demanding conditions - ideal for high-speed and high-temperature environments.

• SKF quality guarantee - consistent global production standards and dimensional accuracy.

For B2B users, the SKF 6215 NR offers an excellent balance between durability, precision, and cost-effectiveness, ensuring long-term uptime of machinery and production lines.

Installation and Maintenance Recommendations

To ensure maximum bearing life and reliability:

• Prepare clean, smooth mounting surfaces and align shafts precisely.

• Avoid impact or excessive force during installation.

• Use the correct fit tolerances for both shaft and housing.

• Apply appropriate lubrication - SKF recommends premium industrial greases for open bearings.

• Regularly inspect bearing temperature, vibration, and noise in continuous-duty environments.

These practices extend bearing service life, minimize downtime, and optimize performance in industrial operations.

FAQ - Common Questions About SKF 6215 NR

Q1: What does “NR” mean in SKF 6215 NR?
It indicates the bearing has a snap ring groove and retaining ring, allowing secure axial positioning in housings or bearing blocks.
