Rock Solid Double Row Self Aligning Ball Bearings Made From Premium Bearing Steel For Hella Smooth Operation And Built Tough Durability With Straight Bore Design Perfect For Cylindrical Shafts At Forty Five By One Hundred By Thirty Six Millimeters
✔️ 2309 Bearing Steel 45mm ID 100mm OD 36mm Width Straight Bore
You receive one double row self aligning ball bearing built as the 2309 model for solid performance on cylindrical shafts. This straight bore piece mounts directly to your shaft while the dual raceways manage minor misalignment and shaft deflection during runtime. Always apply lubricating oil or grease before startup since the bearing steel construction relies on proper film thickness for quiet, smooth spinning.
✅ Two rows of balls share the load evenly to boost capacity beyond standard single row designs
✅ Spherical seating absorbs shaft tilt and housing errors so you dodge binding and wear hot spots
✅ Precision ground bearing steel resists fatigue and delivers long service life under constant stress
✅ Flat bore surface grips securely on straight shafts for easy installation using standard hardware.
💡 Why is adding lubrication essential for maintaining the lifespan of double row self aligning ball bearings?
- Fresh grease acts handy to wash out microscopic grit and keeps metal runners free of abrasive damage.
- A rich lubricant layer cushions the rolling elements against shock loads so the steel inner race avoids cracking.
- Regular top ups hold friction down and keep heat levels low for a silky smooth run until the next overhaul.
