What type of load ratings does it accommodate?
This model has a static load rating of 6.8kN and a dynamic load rating of 22.5kN, enabling it to safely handle various load requirements in different applications.
How does the sealing arrangement enhance its performance?
The dual sealing arrangement effectively keeps contaminants out, reducing the risk of lubrication breakdown and extending the operational lifespan of the bearing.
What specific advantages does the 2-row design provide?
The 2-row configuration allows for greater load capacity and enhanced stability, making it suitable for more demanding applications compared to single-row variations.
Can this bearing be used in electric motor applications?
Yes, its design is specifically tailored for use in electric motors where misalignment can occur, ensuring smooth and effective operation.
Double Row Self - Aligning
Radial Self-Aligning Ball Bearing
These bearings are designed to accommodate shaft deflection when running and will also cope with initial misalignment. The double row bearing is designed primarily to withstand radial load with a small capacity for axial load. Also available with ring seals (rubbing seals) made from oil-resistant, non-wearing synthetic rubber with steel reinforcement on both sides (Type 21).
Open Bearings
ETN9 and KTN9 are Open self-aligning bearings without a seal available in parallel or Taper bores.
Sealed bearings
21TN9 are sealed (NBR) bearings packed with grease with a lithium thickener suitable for temperatures from -40°C to + 100°C. They are sealed for life, so should not be heated above 80°C before mounting and must not be washed out under any circumstances.
- TN suffix denotes polyamide cage
