Main Shaft
Requirements:
- Energy efficiency
- Protect the rotor and stator
- Prevent particle ingression
- Withstand vibration of the shaft
- Facilitate precision positioning of the shaft
- Minimize friction with little heat generation
Trelleborg Solution:
Used on the shaft, high-performance Stefa® radial shaft seals and the Turcon® Varilip® PDR for high-speed environments prevent excessive heat generation, even in dry-running environments, to increase motor efficiency and extend bearing and hardware lifetime. Our Forsheda® V-Ring and GAMMA Seal can be used as secondary seals to prevent the ingress of dirt and/or water. Our solutions cater to a range of environments from standard ingress protection to ultra-clean, washdown settings that demand IP69k ratings.
Back/Front End Cover
Requirements:
- Protect motor components from dust and debris
- Withstand vibration
Trelleborg Solution:
O-Rings and custom-molded components are commonly used, where the motor cover meets the body. Depending on motor design, rotary seals may be required to seal along the shaft.
Terminal Box
Requirements:
Prevent contamination and debris from reaching electrical wiring
Trelleborg Solution:
Depending on the hardware design, O-Rings or engineered molded parts provide effective sealing of the housing cover to protect sensitive electrical connections.
