XSU080318 Cross Roller Bearing 280X355X25.4mm Heavy Duty Rotary Turntable Bearing For CNC Machine Tools With Integrated Bushings Built Tough For Rock Solid Performance And Smooth Daily Grinds

Heavy duty rotary cross roller bearing for cnc tools
✔️ 280x355x25.4mm frame measures 11x13.98x1 inches compact build

This heavy duty rotary turntable bearing provides stable rotational support for cnc machining centers and precision indexing fixtures. It features integrated sealed bushings to handle demanding radial and axial loads during continuous spindle operation. Workers typically install these units on dividing heads and trunnion tables to maintain tight tolerances while cycling heavy stock pieces through automated cutting sequences.

✅ Sealed inner ring design prevents abrasive dust and metal chips from entering the raceway
✅ Accommodates combined thrust and radial forces easily across rotating workholding tables
✅ Ideal for rotary positioning stages and automated pick place indexing machines

💡 What makes a cross roller bearing ideal for rotary index tables?
Selecting the proper rolling element setup keeps your machine tool humming along under heavy cuts. The layered crossed wire arrangement handles mixed directional wear reliably.
- Handy bolt patterns snap right onto standard cast iron pallets without extra adapter blocks
- Sealed track races trap lubricant longer and reduce frequent grease top ups
- Tight internal clearances maintain pinpoint accuracy during fast automated cycles
