Description
Key Features & Technical Highlights
| Description | Core Value |
|---|---|
| Self-aligning ball bearing with automatic heart adjustment function | Compensates for shaft misalignment up to ±2.5°, extending service life and reducing maintenance |
| Model: 2311K-2RS (sealed, reinforced cage) | Double-row design + rubber seals = superior dust/moisture resistance & pre-lubricated for immediate use |
| Dimensions: 95×170×32 mm (ID×OD×W) | Optimized for medium-heavy radial loads in compact industrial layouts |
| Bearing steel construction (GCr15 equivalent) | High hardness, fatigue resistance, and dimensional stability under continuous operation |
| Precision grades: P0/P6/P5 available | Meets SKF-level tolerances — ideal for OEM integration & high-reliability applications |
| Clearance options: C0/C3/C4 | Custom thermal expansion handling — perfect for variable-temp environments (e.g., textile, food processing) |
| Steel/brass cage, grease or oil lubrication | Enhanced cage rigidity & compatibility with standard industrial lubrication protocols |
| OEM/ODM supported | BDL brand (China origin, HS 8482101000) | Fully compliant with global import regulations; scalable production (1M pcs/year) |
| 10–15 day lead time | Carton/pallet packaging | Fast turnaround without compromising ISO-certified quality control |
| Radial load focus + unseparated structure | Simplifies installation, reduces assembly errors vs. split-type competitors |
Applications
Widely used in agricultural machinery, conveyor systems, pumps, fans, and textile equipment where shaft deflection or mounting inaccuracies occur.
Why Choose This Over Generic Alternatives?
Unlike standard self-aligning bearings, this 2311K-2RS features SKF-aligned geometry, tighter raceway surface finish (<0.2 μm Ra), and dual-lip 2RS sealing — delivering 35% longer L10 life in real-world trials.
FAQ
Q: Is this interchangeable with SKF 2311 K 2RS? A: Yes — identical dimensions, load ratings, and ABEC/P5-compliant tolerances.
Q: Can it handle axial loads? A: Limited axial capacity (≤0.3×radial load); use only where misalignment compensation is primary.
Q: What’s the max operating temperature? A: 120°C continuous (with lithium complex grease).
Q: Do you supply test reports? A: Yes — material certs, vibration (Z2/V2), and noise level (≤28 dB) reports included.
