(Gamesa 1U6001NDE32)**

The BEARING 6332MC3 Internal Ring Insulated is a heavy-duty, insulated deep-groove ball bearing built for demanding applications such as wind-turbine generator assemblies, where both mechanical robustness and electrical isolation are required.

This bearing uses the insulated bearing technology of SKF — ensuring protection against shaft currents and stray electrical discharge, thereby enhancing reliability and extending service life in electrical generator environments.Reference:

Key Features

• C3 Internal Clearance (MC3) – Allows for thermal expansion, elevated operating temperatures, and dynamic load accommodation — ideal for heavy-duty rotating machines.

• Insulated Internal Ring / Insulation Technology – SKF INSOCOAT® (or equivalent insulated bearing design) prevents electrical current through the bearing, protecting against fluting or electrical damage on races or balls.

• Deep-Groove Radial Design – Capable of handling substantial radial loads and moderate axial loads in both directions while ensuring smooth rotation and long service life.

• Wind-Turbine & Generator Ready – Specified for use with Gamesa turbine assemblies (PN 1U6001NDE32), making it suitable as an OEM-class replacement/spare bearing.

Dimensions & Mechanical Specs (per SKF 6332 series)

• Bore (d): 160 mm SKF+1

• Outer Diameter (D): 340 mm SKF+1

• Width (B): 68 mm SKF+1 WEIGHT - 17.3 KG

These dimensions provide robust capacity for radial and axial loads, and suit large-diameter shafts common in turbines or heavy industrial machines.

Typical Applications

• Wind turbine generator non-drive / drive-end bearings

• Large electric motors operating under heavy load and exposure to shaft currents

• Industrial rotating equipment requiring both mechanical strength and electrical isolation
