|---|---|
| S71916 | Denotes the bearing series and size (80mm bore, 110mm OD, 16mm width). |
| C | Specifies a 15° contact angle. |
| D | Indicates the bearing is supplied with a preload for enhanced rigidity. |
| HC | Signifies the use of hybrid ceramic balls (Silicon Nitride). |
| P4 | Defines the tolerance class (ABEC-7 / ISO P4), ensuring ultra-precision. |
| A | Specifies the bearing is lubricated and sealed. |
S71916 CD/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Running Accuracy: The preload applied during manufacturing minimizes axial and radial play, resulting in exceptional system stiffness and precise shaft positioning, crucial for high-precision machining.
- Superior High-Speed Capability: The combination of lightweight ceramic balls (reducing centrifugal forces) and a phenolic cage allows for a very high limiting speed of 15,000 rpm, reducing friction and heat generation.
- Extended Service Life: Hybrid ceramic construction offers superior resistance to wear and is less susceptible to lubrication failure, significantly increasing bearing service life in demanding conditions.
- Maintenance-Free Operation: The bearing is sealed and comes pre-lubricated, protecting against contamination and providing long-term, maintenance-free performance within the specified temperature range.
