Mô tả sản phẩm
1. Product Overview

RNA69/32 is double row machined needle roller bearing without inner ring, assembled as an integrated unit including flanged outer ring, needle rollers and stamped steel cage. It features compact cross-section, outstanding radial load capacity and structural rigidity. The bearing adopts quenched and ground shaft surface as rolling raceway to save installation space, ideal for compact mechanical structures bearing heavy radial loads.

3. Core Advantages
  1. Double row needle roller design delivers higher radial load capacity and rigidity compared with single row needle bearings
  2. Inner ring-free structure greatly reduces radial occupied space for miniaturized mechanical layout
  3. Integrated flanged outer ring stably guides the cage, with built-in oil groove for convenient supplementary lubrication
  4. High-rigidity outer ring can be directly mounted into light alloy housings without deformation
  5. Allows minor bidirectional axial offset between shaft and housing during operation
  6. Standard metric dimension, fully interchangeable with mainstream same-spec needle roller bearings
  7. 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.
