Rock Solid Double Row Self Aligning Bearing With Double Rubber Seals And Plastic Cage For Shaft Misalignment And 20 mm Bore 47 mm Outer Diameter 18 mm Width Abec 1 Precision Hefty Load Rating Industrial Workhorse Performance

Heavy Duty Double Row Self Aligning Ball Bearings
✔️ Single unit 20mm inner 47mm outer 18mm thick sealed bearing

You need steady rotational support when shafts deflect or mount unevenly. This double row self aligning ball bearing handles moderate radial loads and low thrust forces. The concave sphered housing rings let you adjust angles during install or operation. Sheet steel reinforced rubber seals stay handy for trapping factory grease while blocking dust. Polyamide cages keep the balls spaced to stop friction and lower vibration in your machinery.

✅ Double row construction resists heavier side loads on rotating shafts
✅ Cylindrical bore fits standard straight metal sleeves without modification
✅ Through hardened chromium steel races stand firm under repeated stress cycles
✅ Normal radial clearance allows parts to expand and contract safely during heat spikes
✅ Operating temperature range spans forty to one hundred twenty degrees Celsius

💡 What benefits do sealed self aligning bearings deliver for misaligned motor mounts? The internal geometry moves smoothly when shafts bend or sit crooked. - Double row ball tracks share heavy radial forces so individual components never wear out early - Flexible inner races slide along spherical grooves to fix angular errors right away inside tight frames - Factory filled grease stays trapped behind thick rubber lips to make routine checks handy - Standard tolerance classes fit straight cylindrical bores for quick swap ins on worn countershafts
