Angular Contact Ball Bearing
Wholesales 2210-2RS 2311K-2RS Self-Aligning Ball Bearings with Auto Heart Adjustment
Basic Info
| Inner Diameter | 95 mm |
| Outer Diameter | 170 mm |
| Width | 32 mm |
Introduction
The 2311K-2RS is a double-row, unseparated self-aligning ball bearing with radial load capacity. Made of high-grade bearing steel, it features steel or brass cage, P0–P2 precision ratings, and C0–C4 clearance options. Ideal for applications requiring misalignment compensation and reliable performance under moderate loads.7

Product Details
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.
