Product Details
Key Features & Technical Highlights
| Description | Core Value |
|---|---|
| Self-aligning double-row ball bearing (2310K-2RS) | Automatic heart adjustment compensates for shaft misalignment up to ±2.5° — extends service life by 40% vs. standard radial bearings |
| 95×170×32 mm metric dimensions, P0–P2 precision grades | Direct SKF-compatible replacement; meets ISO 15 and ABEC 1–9 tolerances |
| Double-sealed 2RS design with food-grade grease | Dust/moisture resistance (IP54) — ideal for humid or dirty industrial environments |
| 60° contact angle + steel/brass cage options | Superior radial & moderate axial load capacity; brass cage enhances high-speed stability |
| Bearing steel (GCr15), heat-treated to HRC 60–64 | Hardness and fatigue resistance validated per ISO 281 L10 life calculation |
| C0/C3/C4 clearance variants | Precise thermal expansion control — critical for pumps, gearboxes, and conveyors |
| OEM/ODM support + BDL trademark (China origin, HS 8482101000) | Full documentation, traceable batch numbers, 1M units/month capacity |
| Carton/pallet packaging with anti-rust protection | Meets ISTA 3A shipping standards — zero damage in global transit |
| ISO 9001-certified manufacturing & 12-month warranty | Third-party inspection reports available upon request |
| Used in textile machinery, agricultural gearboxes, mining conveyors | Proven reliability in high-vibration, off-center load applications |
Why choose this self-aligning bearing over generic alternatives? Unlike rigid deep-groove models, its spherical outer ring raceway enables real-time alignment correction — reducing edge stress, noise, and premature failure. Compared to NSK or Timken equivalents, it delivers identical performance at 18–22% lower landed cost, with faster lead time (10–15 days). Frequently asked: “Can it replace SKF 2310 K 2RS?” Yes — identical dimensions, load ratings, and sealing. “Is C3 clearance pre-installed?” Standard; custom clearance available. “What’s the max speed with grease lubrication?” 4,200 rpm (dm = 132.5 mm).
