Q1: Are MR88N and MI72N two independent usable bearings?
A1: No. MR88N is only the outer ring & needle roller assembly without inner race; MI72N is the matched inner ring. They must be used together as one complete bearing unit. Separate parts cannot operate normally.
Q2: What are the dimensions of MR88N+MI72N?
A2: Bore 114.3 mm (4.5"), Outer Diameter 177.8 mm (7"), Width 63.5 mm (2.5").
Q3: Can this bearing work at high speed?
A3: It is designed for heavy radial load, recommended for low and medium speed operation.
Q4: Does this bearing support re-lubrication?
A4: Yes. The outer ring has built-in lubrication groove and oil hole for periodic grease replenishment.
Q5: Is interchangeability available with McGill original MR88N/MI72N?
A5: Yes, our GQZ bearing maintains standard inch dimensions for direct replacement.
