Heavy Duty Two Pack Axk5578 Thrust Needle Roller Bearings With AS5578 Washers 55 mm Bore 78 mm OD 5 mm Width Hella Rock Solid Build Designed For Smooth Zero Drag Motion On Rough Machinery All Day Long
✔️ 55 mm bore 78 mm outer diameter five width mil spec washers
This pack of two sealed thrust needle roller bearings handles heavy axial loads on rotating machinery. You will mount them easily on tractor axles, trailer spindles, and conveyor systems.
✅ Bearing steel rollers tolerate high heat and carry heavy axial loads✅ Steel cage spacing keeps needles aligned to lower vibration noise
✅ AS5578 spring steel washers resist scraping in tight mounting zones
✅ Handles 1488 kN static and 304 kN dynamic ratings at 3440 rpm max
💡 Why do mechanics find needle roller thrust pads so handy for rough farm equipment shaft alignment compared to regular ball setups?
A compact stack of tiny cylindrical pins spreads harsh forward forces across a wider contact area. This tight arrangement locks the turning spindle dead center while fighting side drift.
- Slender roller layers glide over polished inner races to drop friction temperature quickly.
- Flat washer bases cover awkward frame gaps without demanding custom machining labor.
- Direct weight sharing keeps drive belts tensioned steady through heavy field work.
