Spider Coupling, Rotex 28 - Part # 1901008PP

The ROTEX coupling consists of two hubs (usually made of aluminum or steel) and an elastomer ring (the spider). The spider is placed between the hubs.

• The motor shaft is connected to one hub, and the pump shaft is connected to the other hub.
• The elastomer spider sits between the hubs, transmitting torque while allowing for slight misalignment.
• The spider’s teeth are crowned to avoid edge pressure if the shafts are misaligned
• Regular inspection ensures the spider is in good condition.

Benefits:

• Misalignment Compensation: The coupling accommodates any misalignment due to manufacturing inaccuracies or thermal expansion.
• Durability: ROTEX couplings are durable and reliable, making them suitable for demanding applications.
• Vibration Damping: In a vacuum pump, minimizing vibrations is essential for efficient operation.
