Actuator Housing
Requirements:
- Prevent ingress of dust and debris
- Wide-ranging chemical compatibility
- Protection from electromagnetic interference (EMI) and radio
- frequency interference (RFI)
Trelleborg Solution:
Depending on the hardware design, O-Rings, gaskets or engineered molded parts provide effective sealing of the housing cover to ensure actuator performance.
Low-Friction Motion Components
Requirements:
- Enable energy efficient operation with low-friction properties
- Facilitate smooth motion
Trelleborg Solution:
Utilizing our engineering expertise and advanced thermoplastic processing technology, we manufacture lead nuts, bearing carriers, lead screw scrapers, glides and slides, which are robust, resistant to wear and minimize friction to maximize system efficiency.
Rod Seal
Requirements:
- Facilitate high frequency duty cycles
- Seal under high speeds with minimal heat generation
- Enable smooth, consistent motion
- Prevent particle ingression and contamination
Trelleborg Solution:
Zurcon® polyurethane seals are commonly used along the shaft. The Zurcon® U-Cup RU9 serves as the primary seal and is paired with a double-acting Zurcon® Scraper DA22 for additional protection. Turcon® PTFE-based Variseal®, which offers superior low-friction properties to eliminate stick-slip, is the optimum choice for high-precision actuators.
Linear Wear Rings and Bearings
Requirements:
- Extend linear shaft life by protecting surfaces from wear
- Minimize friction
- Facilitate precision motion
- Withstand high side loads
Trelleborg Solution:
HiMod® or Turcite® Slydring® wear rings and piston and rod seals, such as the Turcon® Glyd Ring® HZ provide effective sealing performance along the shaft. The Slydring® enhances stability, in particular under high side loads, and provides an additional barrier to prevent contamination.
