Swing grinding or upper structure play developing on your R80-7 or R75-7? A worn R80-7 slew ring develops ball groove pitting that creates cab rocking during swing and accelerates pinion tooth wear. RITO supplies this heavy-duty slew ring to restore the tight, smooth upper structure rotation your Hyundai R80-7 requires for precise digging.

Ball groove hardened uniformly across the full circumference to HRC 55-60, preventing brinelling and flat-spot development under continuous high-cycle compact excavator swing duty.
Slew ring specification covers both crawler R80-7 and wheeled R80W-7 variants, as well as R75-7 and R75W-7, addressing the full Hyundai 8-tonne compact range.
Internal gear teeth cut to correct Hyundai R80-7 module for correct mesh with swing pinion, ensuring smooth, noise-free cab rotation without backlash.
Double lip seals on both seal races retain grease and exclude abrasive contamination that shortens ball and groove service life in compact excavator duty.
FAQ
Q: What symptoms indicate the R80-7 slew ring needs replacing?
A: Upper structure rocks side to side under load, audible ball grinding during slow swing, vertical play measurable at the counterweight above 1.5 mm, and accelerated swing pinion tooth wear from misaligned ring.
Q: Is the R80-7 slew ring the same as R75-7?
A: R80-7 and R75-7 use the same slew ring specification. Confirm by matching inner bore, outer diameter and gear tooth count when ordering.
Q: What grease interval should I follow after fitting a new R80-7 slew ring?
A: Grease every 50 hours minimum. Apply until fresh grease purges from the lower seal, then rotate the upper structure through 360 degrees to distribute grease to all balls.
Q: How to confirm this slew ring fits my R80-7?
A: Match inner bore, outer diameter, bolt count and gear tooth count. Provide machine serial number to our team for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
