01. Optimized Large-Bore / Thin-Section Ratio

The 6711-ZZ allows for a 55mm shaft to be supported within a very small radial clearance. This "Thin-Section" geometry is critical for engineers looking to route electrical wiring, pneumatic lines, or coolant through the center of a rotating shaft while keeping the overall machine size manageable and lightweight.

02. Low-Friction Metal Shielding (ZZ)

Equipped with two non-contact pressed steel shields, the 6711-ZZ ensures that factory-applied lubrication stays within the raceways while preventing the entry of larger contaminants. Because the shields do not touch the inner ring, there is virtually zero drag, allowing the bearing to operate at higher speeds with much lower heat generation than sealed alternatives.

03. Precision Chrome Steel Construction

Manufactured from vacuum-degassed GCr15 chrome steel, this bearing offers exceptional fatigue life and dimensional stability. The high-grade balls and polished raceways ensure minimal vibration and noise, which is vital for sensitive applications like optical tracking and laboratory automation.

Interchange Part Numbers

Compatible with the following industry-standard thin-section designations:

• SKF: 61711-2Z / 6711-2Z
• NSK: 6711ZZ
• FAG: 6711.2Z
• NTN: 6711ZZ
• KOYO: 6711ZZ

Design & Configuration

The 6711-ZZ is supplied pre-greased for maintenance-free operation under normal conditions. For high-temperature environments or vacuum applications, we can provide customized lubrication options or cage materials. If your application requires protection against liquids or fine dust, we recommend the 6711-2RS (contact rubber seals). Stainless steel (AISI 440C) versions are also available for maximum corrosion resistance in specialized sectors.

"The 6711-ZZ is the definitive solution for engineers demanding high-speed reliability and a minimalist footprint for large-diameter shaft applications."
