FAQs of Bosch Rexroth R 165121220:

Q: How do I install the Bosch Rexroth R 165121220 Ball Runner Block into my linear rail system?

A: Installation involves sliding the runner block onto a compatible Bosch Rexroth Ball Rail. Ensure the guide rail is clean, properly aligned, and supports the 20 mm size specified. Follow the manufacturers torque settings during mounting for optimal precision and performance.

Q: What are the primary benefits of using this ball runner block in industrial automation?

A: The R 165121220 offers high load ratings in all directions, precise movement, and superior durability due to its high-tensile, corrosion-resistant bearing steel. These features enable reliable linear motion, reduced downtime, and long-term performance in demanding automation environments.

Q: When should relubrication be performed, and what is the process?

A: Relubrication intervals depend on operational intensity and environment. As a guideline, relubricate when motion becomes less smooth or after significant usage cycles. Inject compatible lubricant through the built-in lubrication ports to maintain peak performance.

Q: Where is the Bosch Rexroth R 165121220 typically used?

A: This ball runner block is well-suited for linear guidance systems in industrial automation, machine tools, production machinery, and other applications requiring high-precision and high-load linear movement.

Q: What is the maximum speed this product can support, and does it affect its performance?

A: The R 165121220 can operate at speeds up to 5 m/s. While capable of fast operation, maintaining correct lubrication and rail alignment is essential to ensure smooth motion and avoid wear at higher speeds.

Q: How does the preload class 2 (light preload) enhance the blocks performance?

A: The light preload minimizes play between the block and rail, improving guidance accuracy and motion stability. This results in smoother, more precise movement crucial for high-precision tasks.
