HZ-GSM Engineering plastic sliding bearing

The most popular G material in the world. The G series bearings can meet various different needs in a wide range of fields - they are truly versatile. Typical applications include mid to high end loads, moderate operating temperatures, and speeds.

Dry operation, maintenance free
Wear resistance
Resistant to dust and dirt
Low noise, pollution-free
high performance-price ratio

Suitable occasions:
Economic all-round bearing
Maintenance-free, dry operation
damping
High wear resistance
Resistant to dust and dirt
high performance-price ratio
Capable of withstanding moderate to high loads
Below-average operating speed
Used for swinging and rotating movements

Not applicable for:
When drilling holes on the wall surface is required
When excellent wear resistance is required
When universal chemical resistance is required
If the temperature remains above+130 ℃
Used for underwater applications
