1. Product Specifications and Comparisons

The 6011 series deep groove ball bearings (6011, 6011ZZ, 6011RS, 60112RS) from NTN, NSK, and Koyo are designed for high-speed automotive applications. Key specifications include:

Model Bore Diameter (mm) Outer Diameter (mm) Width (mm) Seal Type Load Capacity (kN)
6011 55 90 18 Open 22.5
6011ZZ 55 90 18 Metal Shield 21.8
6011RS/2RS 55 90 18 Rubber Seal (Single/Double) 20.3

Key Differences: ZZ shields offer dust resistance; RS/2RS provide superior waterproofing. NTN bearings prioritize low noise, NSK excels in load distribution, and Koyo optimizes high-speed stability.

2. Detailed Applications

These bearings are critical in automotive systems requiring precision and durability:

  • Electric Motors: Reduce friction in EV drivetrains.
