SNR 2214 Double‑Row Self‑Aligning Ball Bearing - 70x125x31 mm

SNR 2214 Double‑Row Self‑Aligning Ball Bearing - 70x125x31 mm

The SNR 2214 is a double‑row self‑aligning deep‑groove ball bearing engineered for demanding industrial use. With an inner diameter of 70 mm, outer diameter of 125 mm, and width of 31 mm, this bearing excels in managing radial loads, minor angular misalignment, and moderate axial forces in both directions.

Keywords embedded: SNR 2214, self‑aligning ball bearing, double‑row bearing, 70x125x31, deep‑groove self aligning, bearing for misaligned shafts, industrial bearing SNR.

Key Features:

• Self‑aligning design: spherical outer ring raceway compensates shaft misalignment for smoother operation and reduced friction

• Double‑row deep‑groove configuration: supports high radial loads and axial load in both directions up to a limited extent

• Precision dimensions: 70 mm bore, 125 mm outer diameter, 31 mm width; fits standard housing sizes

• Normal internal clearance (CN): balanced operation and adequate thermal expansion allowance

• Pressed steel cage ensures robust performance across temperature range - up to ~120 °C and rotational speeds up to ~6 700 RPM

Performance Specifications:

• Dynamic load rating (C): approx. 43.9 kN

• Static load rating (C₀): approx. 17.1 kN

• Fatigue load limit (Cᵤ): around 0.78 kN

• Suitable for operations between -40 °C and +120 °C; recommended maximum speed ~6 700 RPM

Applications:

Ideal for shafts with alignment errors, such as:

• Electric motors and gearboxes

• Agricultural and textile machinery

• Conveyor shafts and heavy-duty rotary equipment

• Fans, pumps and systems with misalignment risk

Benefits:

• Compensates for minor misalignments, reducing stress on housing and shaft

• High radial load capacity for heavy-duty applications

• Long life, low-maintenance operation in industrial environments

• Globally recognized dimension and interchangeability among SNR, NSK, SKF brands

• Easy integration in B2B logistics and spare part workflows

❓ FAQ - Frequently Asked Questions

Q: What does “self‑aligning” mean?
A: The outer ring’s spherical raceway allows angular misalignment (within limits), protecting bearings from shaft deviation.

Q: Can this bearing handle axial load?
A: Yes—but only to a limited degree in both directions due to the double‑row configuration.

Q: What is the maximum operating speed?
A: Approximately 6 700 RPM for typical conditions; actual speed limits depend on lubrication and temperature.

Q: What temperature range can it withstand?
A: From -40 °C up to +120 °C without structural compromise.

Q: Is grease lubrication required?
A: Pre-lubricated models are available; re-lubrication depends on operating conditions and maintenance plans.

Q: How quickly can I get this bearing?
A: Available from our Lublin warehouse; 24 h shipping is standard for most orders.
