Tra 3648 Thrust Roller Bearing Washer Tr Type Open Face Heavy Duty Workhorse 2 1/4 Inch Bore And 3 Inch Outer Diameter Built Like A Tank With Precision Flush Ground Chromium Steel For Hassle Free Swaps And Battle Tested Daily Grind Reliability

Heavy duty thrust bearing washer for shafts and housings
✔️ 2 1/4 inch bore by 3 inch OD flush ground raceway surface

This thrust roller bearing washer gives you a hard raceway when your frame parts cannot take the pressure. You slide it onto your drive shaft or lock it inside a housing to cut down on spinning friction. It handles daily grinding in steering boxes, clutch plates, machine tools, and marine engines.

✅ Through-hardened chromium steel fights deformation under heavy axle loads
✅ Precision flush-ground raceways boost top speed and track accuracy
✅ Open face design mates cleanly with Koyo NTA series needle cage units
✅ Flush machined mounting faces guarantee straight alignment every time

💡 Why is a thick thrust washer so handy for tough industrial gearboxes?

This part builds a solid contact zone that stops your rollers from chewing up weak metal.

- Low alloy chromium plate resists flaking under sustained crushing stress
- Ground bearing seats eliminate wobble and extend spindle life cycles
- Needle roller cages glide freely against hardened contact surfaces
- Straightforward housing swaps keep production lines moving without delay
