Miniature ball bearings play an essential role in compact, high-speed rotating systems. Among them, the 696 시리즈 (696ZZ / 696-2알에스) is one of the most widely used micro deep groove ball bearings, known for its small size, stable performance, and long service life.

As a professional precision bearing manufacturer, NKMB provides high-quality 696 miniature ball bearings with excellent noise level, 내구성, and sealing performance that meet international standards.


1. 696 Bearing Size & Basic Parameters

Parameter Value
내경 (d) 6 밀리미터
외경 (D) 15 밀리미터
너비 (B) 4.5 밀리미터
구조 Single-row deep groove ball bearing
시리즈 696

These dimensions make the 696 bearing ideal for tight spaces, micro transmission systems, and high-speed rotating parts.


2. Types of 696 Bearings: ZZ and 2RS

✔ 696ZZ — Metal Shielded

  • Equipped with 더블 메탈 실드 (ZZ)

  • Protects against dust and small particles

  • Allows higher RPM

  • Suitable for clean environments and small motors

✔ 696-2RS — Rubber Sealed

  • Equipped with double rubber seals (2알에스)

  • Excellent water, moisture, and oil protection

  • Slightly lower RPM than ZZ

  • Best for outdoor, humid, or dusty environments

NKMB offers both types depending on different usage scenarios.


3. 재료 옵션 (NKMB Standard)

✔ Chrome Steel GCr15 / 52100

  • 높은 경도

  • Strong wear resistance

  • Long service life

  • Suitable for most mechanical applications

✔ Stainless Steel 440C / 304 / 316 (Optional)

  • Anti-rust and anti-corrosion

  • Ideal for food machinery, 의료 기기, water environments


4. 정밀, Clearance & Noise Level

Item NKMB Standard
Precision Class ABEC-1 / ABEC-3 (ABEC-5 optional)
Radial Clearance 씨0 (standard) / 다3 (high-speed)
Noise Level Z1 / Z2 low-noise grades
윤 활 High-speed or anti-water grease

NKMB 696 bearings are widely chosen for devices requiring smooth rotation, low friction, and minimal vibration.


5. Load Ratings (Reference)

Item Value
Dynamic Load (C) ~1.36 kN
Static Load (씨0) ~0.52 kN
Max Speed (ZZ) 까지 45,000 RPM
Max Speed (2알에스) 까지 28,000 RPM

Exact load may vary depending on materials and lubrication.
