⚙️Product Description:
The 1306 (Cylindrical Bore) and 1306K (Tapered Bore 1:12) are heavy-series double-row self-aligning ball bearings engineered to handle medium radial loads and accommodate dynamic shaft deflections. Featuring a 30mm inner bore, 72mm outer diameter, and 19mm width, this 1300-series model incorporates a spherical outer raceway housing two rows of precision steel balls guided by a robust steel or polyamide retainer. Its automatic angular adjustment capability allows smooth, unhindered rotation even when mounting alignment errors or frame flexing occurs under load. Available in both straight bore and tapered bore (for adapter sleeve mounting like H306), we supply these high-reliability self-aligning bearings under our proprietary RMO brand while supporting global multi-brand OEM direct sourcing for agricultural machinery, conveyor system, and textile equipment builders.
⚙️Product Features:
- Self-Aligning Spherical Outer Raceway: Spherical outer ring layout allows up to 2.5–3 degrees of angular misalignment, preventing edge stress loading caused by shaft deflection.
- Heavy 1300 Series Cross-Section: Reinforced raceway wall thickness and larger steel ball complement deliver superior radial load capacity compared to 1206 series counterparts.
- Cylindrical (1306) & Tapered (1306K) Options: Tapered bore version permits easy mounting with adapter sleeves on smooth optical shafts without precision shoulder machining.
- Ultra-Low Friction & Cool Running: Spherical rolling motion produces minimal friction torque and heat buildup, prolonging lubricant life during continuous operation.
⚙️Product Application:
Engineered for frame alignment tolerance, vibration damping, and smooth radial load support, the 1306 / 1306K self-aligning ball bearing is widely specified in:
- Agricultural machinery: grain harvester drive shafts, tractor PTO linkages, and planter seed metering units.
- Textile & paper processing: textile spinning frame rollers, carding machine drives, and paper rewinder guide shafts.
- Material handling & conveyors: bulk belt conveyor drive pulleys, bucket elevator head shafts, and sorting line rollers.
- Industrial fans & blowers: centrifugal ventilation fan shafts, industrial exhaust blowers, and air handling units.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
