1. Product Description
BSFP is a two-piece bidirectional piston combination seal, also known as PU Glyd Ring. It consists of a wear-resistant PU sliding seal ring and an elastic O-ring for preloading. Its groove dimension is interchangeable with GSF PTFE Glyd Ring (ISO 7425 standard), which allows convenient replacement for hydraulic cylinders.
2. Structure
- Main sliding ring: Polyurethane (PU)
- Preload O-ring: NBR (standard) / FKM (custom for high temperature & chemical resistance)
3. Technical Parameters
- Sealing type: Bidirectional piston seal for double-acting hydraulic cylinders
- Working pressure: ≤30 MPa, short-term peak up to 35 MPa
- Reciprocating speed: ≤0.5 m/s
- Working temperature: -35℃ ~ +120℃ (NBR O-ring)
- Applicable media: Mineral hydraulic oil, anti-wear hydraulic oil
4. Applications
Construction machinery (excavators, loaders, forklifts), hydraulic presses, agricultural machinery, heavy-duty injection molding machine hydraulic cylinders, low-speed & heavy-load hydraulic equipment.
