Details
The RM scraper ring, or GHT/RM, is a component used in hydraulic and pneumatic applications to protect seals and other internal parts from dirt, dust, and moisture. It features a single-lip profile and is made with an elastomeric material (such as NBR or FKM) vulcanized onto a shaped metal ring. This metal ring provides strength and structural support, while the elastomeric part ensures good sealing and adaptability to small imperfections on the contact surface.
Main features:
- Function: Prevents the ingress of external contaminants, protecting seals and other internal parts from damage.
- Design: Single-lip profile, which provides good adaptability to small shaft imperfections.
- Material: Made of an elastomeric material (typically NBR or FKM) vulcanized onto a metal ring.
- Installation: Generally housed in open grooves, which facilitate installation, especially for small diameters.
- Applications: Widely used in hydraulic and pneumatic systems, particularly to protect pistons and rods from contamination.
Advantages:
- Effective protection: Prevents the ingress of dirt, dust, water, and other harmful elements.
- Easy installation: Thanks to the open groove, installation is quick and easy, even for small diameters.
- Good adaptability: The elastomeric material adapts well to minor surface irregularities.
- Strength: The metal ring provides strength and long-term durability.
