N1020K Single‑Row Cylindrical Roller Bearing 100x150x24 Tapered Bore 1:12 Floating Spindle Bearing

1. Product Overview

N1020K is single‑row high‑precision cylindrical roller bearing. Dimensions: 100 mm bore × 150 mm outer diameter × 24 mm width.

Suffix explanation:

• N: Two integral ribs on inner ring, rib‑free outer ring; permits free axial displacement between shaft and housing, used as floating‑end bearing to absorb shaft thermal expansion.
• K: 1:12 tapered inner bore, can mount on tapered shaft or assemble with adapter sleeve for cylindrical shaft installation; radial internal clearance can be adjusted during mounting procedure.

Separable construction: inner‑ring‑roller‑cage assembly can be disassembled from outer ring for convenient installation, inspection and replacement. Cage‑guided cylindrical rollers deliver low‑friction high‑speed performance. Manufactured of fully quenched GCr15 bearing steel. Primarily supports heavy pure radial load, cannot bear axial force. Widely adopted for machine‑tool spindles, large high‑speed industrial motors, heavy‑duty gearboxes, turbo‑compressors and other high‑speed rotary equipment requiring floating‑end compensation and adjustable mounting clearance.

2. Technical Specifications

Mounting‑shoulder drawing, adapter‑sleeve selection guide and performance test reports can be provided upon customer request.

3. Core Advantages

1. 1:12 tapered bore (K suffix): Adjust radial clearance by axial pushing along tapered shaft; compatible with adapter‑sleeve for installation on standard cylindrical shafts, flexible for various fit requirements.
2. N‑type floating‑end design: Rib‑free outer ring allows bidirectional axial sliding, effectively absorbs thermal elongation of shaft and prevents bearing seizure caused by temperature rise.
3. Separable inner‑ring‑roller assembly, simplifies installation, disassembly and on‑site inspection without removing complete housing components.
4. High radial rigidity and heavy radial load‑carrying capacity, suitable for high‑speed heavy‑radial‑load working conditions; not designed for axial load transmission.
5. Super‑finished raceway and roller surfaces, low friction and low heat generation, stable high‑speed running performance for spindle and large‑motor‑class equipment.
6. GCr15 overall quenched bearing steel, stable metallographic structure, excellent anti‑fatigue and wear‑resistant performance for cyclic‑load operation.
7. Standard ISO metric dimension, fully interchangeable with global N1020K bearings, direct replacement without housing modification.
8. Rich custom options: P0/P6/P5 precision grade, multiple clearance groups, brass cage variant, OEM outer‑ring laser marking, neutral export anti‑rust carton, special‑temperature grease filling.
