Seals and bearings are precision components that reduce friction, support loads, and prevent contamination in pneumatic pistons/diaphragms and electric motors.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Hardness | 70-95 Shore A for seals, 58-65 HRC for bearings | |
| Clearance | C3 to C5 for bearings, 0.1-0.5 mm interference for seals | |
| Speed Rating | Up to 20,000 rpm for electric motors, <1 m/s for pneumatic seals | |
| Load Capacity | Dynamic: 5-50 kN, Static: 10-100 kN | |
| Pressure Rating | Up to 300 bar for hydraulic, 10 bar for pneumatic | |
| Temperature Range | -40°C to +200°C |

This component is used in the following industrial products
The core driving mechanism within an actuator that converts energy (pneumatic pressure or electrical power) into linear or rotary mechanical motion.
A mechanical device that converts energy into motion to drive or control a transfer mechanism.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Seals / Bearings.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Seals primarily prevent fluid leakage and contamination ingress, while bearings support loads and reduce friction between moving parts. Both are critical for system efficiency but serve different mechanical functions.
Replacement intervals depend on operating conditions: typically 10,000-50,000 hours for bearings under normal load, and 5,000-20,000 hours for seals, with monitoring for vibration, temperature, and leakage.
No, they are application-specific. Pneumatic seals handle lower pressures but higher cycle rates, while motor bearings require precise tolerances for high-speed rotation. Material and design specifications differ significantly.
