1. Hydraulic Seal Types and Available Series
| Seal Type | Available Series or Models |
|---|---|
| Rod Seals | U Cup, H605, UPR, BS |
| Piston Seals | Glyd, UN, UPI, USI, ODU/YX-D, IUIS, KR, IDU |
| Rod/Piston Seals | UN, UNS, UHS, USH, UPH |
| Wiper Seals | GHK |
| Buffer Seals | HBY |
| V Packing | Fabric-reinforced NBR V Packing Sets |
The selection includes individual sealing profiles and assembled sealing configurations for different hydraulic cylinder positions.
2. Hydraulic Seal Specifications and Operating Conditions
The following specifications are available for selected models. Pressure, temperature, speed, and fluid compatibility vary by product.
| Product / Model | Dimensions (mm) | Material / Construction | Temperature Range | Max. Pressure | Max. Speed | Applicable Fluid |
|---|---|---|---|---|---|---|
| U Cup Rod Seal | 4 × 10 × 4 | PU | -35°C to +100°C | ≤40 MPa | ≤0.5 m/s | Mineral oil-based hydraulic oil |
| BS Series Rod Seal | 6 × 12 × 5 | PU | -35°C to +110°C | ≤40 MPa | ≤0.5 m/s | Mineral oil-based hydraulic oil; water-glycol emulsion |
| H605 Rod Seal | 34.93 × 44.45 × 7.92 | PU | -40°C to +100°C; short-term up to +120°C | ≤35 MPa | ≤0.5 m/s | Mineral oil-based hydraulic oil; water-glycol fluid |
| PTFE Glyd Piston Seal | Not specified | Bronze-filled PTFE + NBR 70 Shore A | -35°C to +110°C | ≤35 MPa | ≤1.5 m/s | Mineral oil-based hydraulic oil |
| HBY Buffer Seal | Standard and custom dimensions | PU/PA | -35°C to +100°C | ≤50 MPa | Not specified | Hydraulic oil; mineral oil |
| GHK Wiper Seal | 35 × 43.6 × 5.3 | TPU / metal reinforcement | -35°C to +100°C | Not specified | ≤1.0 m/s | Not specified |
| Fabric NBR V Packing Set | 115 × 130 × 21.5 | Fabric-reinforced NBR + POM/cotton support rings | -30°C to +120°C | ≤40 MPa | ≤0.5 m/s | Hydraulic oil, water-glycol, petroleum-based fluids |
The H605 temperature specification distinguishes its short-term maximum of +120°C from its regular stated operating range. The maximum pressure of 50 MPa applies to the HBY Buffer Seal, not the entire product range.
