3. Core Advantages

Double row needle roller design delivers higher radial load capacity and rigidity compared with single row needle bearings
Inner ring-free structure greatly reduces radial occupied space for miniaturized mechanical layout
Integrated flanged outer ring stably guides the cage, with built-in oil groove for convenient supplementary lubrication
High-rigidity outer ring can be directly mounted into light alloy housings without deformation
Allows minor bidirectional axial offset between shaft and housing during operation
Standard metric dimension, fully interchangeable with mainstream same-spec needle roller bearings
Customizable options: rubber seals (UU/2RS), high-temperature grease, OEM laser marking, P6/P5/P4 precision grade
Effectively lower equipment abrasion, vibration and maintenance frequency under heavy working loads.

4. Application Scenarios

Industrial gearboxes, speed reducers and transmission assemblies
Hydraulic pumps, hydraulic cylinders and control valve actuators
Automated production equipment and robot joint rotary parts
Construction machinery, agricultural machinery rotating shafts
Textile, printing and packaging heavy-duty rotary rollers
General compact mechanical components bearing heavy radial loads

8. FAQ

Q1: What does RNA stand for?

RNA refers to needle roller bearing without inner ring; NA series is equipped with matched inner ring.

Q2: Exact dimension and matched inner ring model?

Fw32×D47×B30mm; matching inner ring: IR32×40×30 / LRT324030.

Q3: When is a matching inner ring necessary?

If the mating shaft cannot be quenched to HRC60 and mirror superfinished, install separate inner ring as rolling raceway.
