  • For industrial applications involving heavy equipment or automotive parts, select heavy-duty units that can withstand high voltages and loads.
  • Make sure the ball transfer unit can operate effectively within the temperature range of your application environment.

Bosch Rexroth Ball Transfer Units Installation and Maintenance

Proper installation and maintenance are critical to ensure optimal performance and longevity of Bosch Rexroth ball transfer units. Here is a detailed guide to installing and maintaining these devices:

  • Determine the exact locations where the ball transfer units will be installed. Make sure these areas can support the load and are properly leveled.
  • Ensure the mounting surface is clean, level, and free of debris to ensure a stable installation.
  • Place the flange block in the designated area.
  • Use appropriate bolts or screws to secure the device through the flange holes. Make sure the device is securely secured to prevent it from moving.
  • Drill holes in the mounting surface to match the dimensions of the studs.
  • Insert the ball transfer assembly studs into the holes.
  • Attachment: Tighten the nuts on the studs to securely secure the unit in place.
  • Make sure all blocks are aligned correctly to ensure smooth movement of items across the surface.
  • After installation, test the ball transfer units by placing a weight on them to check for smoothness and stability.
  • Monitor balls and housings for wear. Replace any worn or damaged components promptly to prevent further damage and ensure trouble-free operation.
