PTFE Piston Rings & Rider Rings
Product Code : 12
Piston rings, rider rings and bands are manufactured in various designs:
- The function of PISTON RINGS, mounted on the pistons of lubricated or non-lube (oil free) compressors, are designed to ensure that the gas is compressed and to provide a seal between the piston and the cylinder.
- The function of RIDER RINGS, used mainly in oil free or mini-lube compressors, is to support or guide the piston and rod assembly and prevent contact between the piston and the cylinder (risk of seizure).
- One-piece or segmental straight
- Angle cut
- Step cut
- Twin Ring
- Double Twin Ring
- Two Segment
- Pressure balanced
AEW also custom designs rings and has developed specific combinations for particularly problematic and demanding applications. This has also included numerous successful conversions from lubricated to non-lubricated operation. Pressure balanced rings are available, when deemed appropriate for high pressure applications and piston/rider ring combinations are also available for more specific applications.
Large diameter piston rings up to 47” (1200mm) are custom manufactured for special requirements.
