Its high-carbon chromium steel balls and precision-ground raceways offer superior durability and minimal friction, making it ideal for advanced CNC and machine tool spindle applications.

Versatile Application and Reliable Design

With a standard load capacity, 15 contact angle, and single-row angular contact structure, this bearing offers the versatility needed for complex manufacturing and precision equipment. Its open-seal design aids in rapid heat dissipation while supporting lubricants such as grease and oil for varied operational requirements.

FAQs of TPI Precision Bearings 7009 C:

Q: How should the TPI 7009 C Precision Bearing be installed to ensure high accuracy?

A: To achieve optimal accuracy, installation should be conducted in a clean, controlled environment. Use precision tools to handle the bearing and avoid direct impact. Ensure the shaft and housing are within specified tolerances and clean before assembly. Align the bearing carefully, as the precision ground finish and ABEC-7 rating demand exact mounting to maximize performance.

Q: What are the typical applications for the TPI 7009 C bearing?

A: This bearing is ideally used in machine tool spindles, CNC machinery, and various types of precision equipment. Its high-speed rating and superior precision make it suitable for demanding industrial environments where minimal vibration and high reliability are critical.

Q: When is it necessary to use oil lubrication instead of grease for the 7009 C bearing?

A: Oil lubrication is recommended when operating at higher rotational speeds, especially close to the bearings maximum limit of 18,000 RPM. Oil enables better heat dissipation and reduces viscosity drag at high speeds, ensuring the bearing maintains performance and longevity.

Q: Where can distributors and suppliers in India source genuine TPI 7009 C Precision Bearings?

A: Authorized distributors, importers, and suppliers across India stock this bearing. Ensure procurement from official TPI networks or certified vendors to guarantee authenticity, quality assurance, and access to technical support.

Q: What benefits does the phenolic resin cage offer in this bearing?

A: The phenolic resin cage provides excellent strength-to-weight ratio, reducing overall bearing weight while maintaining rigidity. It is well-suited for high-speed applications due to its low friction and heat resistance, supporting stable operation under demanding conditions.

Q: How does the V4/V3 vibration level rating benefit machine tool spindles?

A: The high precision V4/V3 vibration level ensures extremely quiet operation and minimal runout, crucial for maintaining tool accuracy, extending spindle lifespan, and producing consistent, high-quality finishes in machined components.
