8E-NK1-20x47X14 8E-NK1204714 Automotive Needle Roller Bearing 20x47x14mm

1.Product Overview
8E-NK1-20x47X14 and 8E-NK1204714 are completely interchangeable drawn cup needle roller bearings without inner ring, two different marking codes for the same physical bearing. Standard unified dimension: inner matching shaft diameter 20mm, outer diameter 47mm, overall width 14mm.

8E series stands for reinforced thin-wall stamped outer shell structure, integrated cage and needle rollers assembled inside the drawn cup, compact radial thickness design to save radial installation space. Without separate inner ring, directly use hardened and ground shaft surface as rolling raceway, effectively reduce total assembly cost and component quantity for compact transmission units.

High precision cylindrical needle rollers with GCr15 bearing steel material, uniform dimensional sorting, low friction torque and stable rotation under medium-high speed alternating radial load. Stamped thin-wall steel cup with integrated positioning lip to prevent axial displacement during operation. Widely applied to small industrial gearboxes, textile spinning equipment, packaging machinery, light automation conveyor shafts and miniature hydraulic auxiliary drive assemblies.

1. Two part numbers share identical dimension and performance, fully interchangeable for replacement and bulk purchasing, convenient for different customer part code management standards.
2. Ultra-compact radial thin-wall drawn cup structure, greatly reduce radial occupied space, ideal solution for narrow housing compact transmission equipment layout.
3. No independent inner ring design, directly use hardened shaft as raceway, cut spare part procurement cost and simplify overall equipment assembly process.
4. Reinforced 8E stamped outer shell with positioning stop lip, effectively restrict bearing axial sliding, stable positioning under frequent forward-reverse rotation.
5. Strictly graded needle rollers with mirror superfinished surface, evenly distributed load, low running noise and small temperature rise during long continuous medium-high speed operation.
6. Full customizable service support: C3 enlarged clearance, P6 high precision grade, OEM laser marking on outer shell, neutral export carton anti-rust packaging.
7. Integrated cage and needle roller pre-assembled unit, one-step installation without scattered roller falling risk during mass production assembly.
8. Passivation anti-corrosion treatment on outer cup surface, excellent rust resistance for normal indoor and semi-dust light industrial working environments.

1. Q1: What is the relation between 8E-NK1-20x47X14 and 8E-NK1204714?
   A1: They refer to the same drawn cup needle roller bearing, only two different marking number formats, fully interchangeable in dimension, load and installation performance.
2. Q2: What does no inner ring mean for this bearing?
   A2: This bearing does not contain a separate inner ring; you need to use a hardened, ground shaft surface as the rolling raceway for needle rollers.
3. Q3: What advantages does 8E series drawn cup bearing have?
   A3: Ultra-thin radial wall saves installation space, integrated pre-assembled rollers and cage avoid scattered parts during assembly, built-in stop lip prevents axial shifting.
