Product Overview

MR88N+MI72N is a heavy-duty separable inch-size needle roller bearing assembly from MR series. MR88N refers to the outer ring & needle roller-cage unit without inner race; MI72N is the matched separate inner ring. Only assembled together can they form a complete working bearing unit. The outer ring features built-in lubrication groove and oil hole for convenient re-lubrication. Made of high-quality bearing steel, this unit delivers outstanding radial load capacity, widely adopted for heavy-load low-to-medium speed industrial equipment as replacement for McGill Cagerol bearings.

FAQ

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.
