Product Details
Key Features & Technical Highlights
| Description | Core Value |
|---|---|
| Self-aligning ball bearing (2311K-2RS) | Automatic misalignment compensation up to ±2.5° — protects shaft & housing from premature wear |
| Double-row, radial load design | Higher load capacity vs. standard single-row bearings; ideal for heavy-duty industrial use |
| Bearing steel construction (GCr15) | Superior hardness, fatigue resistance and dimensional stability under dynamic loads |
| Double-sealed with rubber (2RS) | Enhanced dust/moisture protection + pre-lubricated for maintenance-free operation |
| Precision grades P0–P2 available | Tight tolerances ensure smooth rotation, low noise & extended service life |
| Clearance options: C0/C3/C4 | Optimized thermal expansion handling — perfect for variable temperature environments |
| 95×170×32 mm metric dimensions | Direct OEM replacement for SKF 2311K/2311-2RS — seamless integration |
| Steel or brass cage | High-speed stability & reduced friction — supports continuous high-RPM applications |
| Made in China | BDL brand | HS 8482101000 | ISO 9001-certified production; 1M units/year capacity ensures fast, reliable supply |
| OEM/ODM support & carton/pallet packaging | Custom branding, labeling & logistics — tailored for global distributors & end-users |
Engineered for demanding applications: conveyor systems, agricultural machinery, fans, pumps, and textile equipment. Outperforms generic alternatives with tighter runout control, superior raceway finish, and consistent preload performance. All units undergo 100% dimensional & noise inspection. Have a project?
