Double Row Self-Aligning Bearing With Extended Inner Ring Fits 45mm Bore, 85mm Outer Diameter, 58mm Width, Built Like A Tank Up To 6000 RPM, Open Style For Grease Injection, Polyamide Cage Sheds Weight And Keeps Things Rolling
Double Row Self-Aligning Steel Bearing 45mm Bore 85mm OD
✔️ 45mm bore, 85mm OD, 58mm wide, extended ring mounts on shaft
You get steady performance even when your shaft shifts under pressure. This double-row bearing stays aligned on its own to guard against damage from bending or sloppy mounts. The open face lets you inject fresh grease directly into the rolling elements. It handles moderate radial loads and light axial push back, making it a solid choice for conveyor systems, countershafts, and printer mechanisms.
✅ Extended inner ring grabs the shaft tight so you skip extra spacers and lock position fast.
✅ Spherically ground races absorb angle errors from shaft flex or mounting slop in tough setups.
✅ Glass fiber polyamide cage holds balls apart to cut vibration and noise at speeds up to 6000 RPM.
✅ Chromium steel core resists denting and handles heavy forces day after day without losing shape.
💡 How does a dual-row self-aligning unit handle bent or bowed shaft conditions?
Worn machinery often develops uneven spacing between mounts, causing regular bearings to seize or crack.
This handy upgrade keeps everything rolling smoothly by adjusting its internal angles real quick.
- Spherical outer raceways allow the inner ring to pivot and correct shaft misalignment automatically.
- Dual rows distribute heavy radial forces evenly to prevent localized stress on the steel components.
- Clearance gaps in the open configuration enable direct access for grease pumps to reach all rolling surfaces.
