HK2012 Needle Roller Bearing 20×26×12mm Compact Drawn Cup Equipment Bearing Wholesale GQZ
- HK2012 is a standard open-end drawn cup needle roller bearing with compact dimensions 20×26×12mm, designed without an inner ring. It consists of a thin precision stamped steel outer cup, multiple needle rollers and integrated steel cage as a single assembly. Its ultra-thin radial cross-section greatly saves installation space compared to ball bearings of the same bore size, while dense needle roller arrangement delivers outstanding radial load capacity and structural rigidity. This bearing requires a hardened and ground shaft surface to act as the inner raceway during installation. Standard open version fits clean lubried environments; RS and 2RS rubber sealed variants are available to resist dust and splash. It is a cost-effective compact rotary component widely adopted for light & medium-duty mechanical transmission requiring high load capacity in limited installation space.

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-lubriion?
A4: Yes. The outer ring has built-in lubriion 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.
