WBG-10 Wind Turbine Lubricating Grease (Main Bearing)

Category:

Grease and Consumable

Product advantages

Wide Temperature Range: Extends grease replacement and replenishment intervals, effectively prolonging the service life of wind turbine main bearings. Excellent Water and Corrosion Resistance: Provides robust protection against water and corrosion. High Load Capacity: Effectively prevents scuffing under heavy or impact loads. Superior Anti-friction Properties: Reduces frictional heat in bearings while providing outstanding fretting wear resistance. Good Low-Temperature Start-Up Performance: Allows equipment to start with minimal friction torque over a wide temperature range.

Application

Suitable for lubrication and sealing of wind turbine main bearing systems using centralized grease supply or grease injectors. Suitable for lubrication and sealing of equipment under other low-speed heavy-load conditions. Suitable for lubrication of bearing systems requiring high load resistance and long-term lubrication. Usable within a temperature range of -40℃ to 120℃.

产品介绍

Product Overview

WBG-10 wind turbine lubricating grease is a high-performance grease designed for the harsh conditions of continuous operation under heavy loads at low speeds in the main bearings of large wind turbine. It is formulated with high-performance synthetic oil as the base oil and thickened with a special metal soap base. This grease can adapt to the frequent low-temperature starts and heavy-load low-speed continuous operation requirements of wind turbine, providing excellent extreme pressure capacity and anti-wear performance to effectively control stress wear and fretting wear of the bearings.
