WGG-40R/WGG-40R(W) Rust-Proof Open Gear Grease (Open Gear Ring)

Category:

Grease and Consumable

Product advantages

Outstanding Rust-Proof Performance: Effective rust protection for equipment operating in high salt and alkaline environments, such as coastal areas. High Load-Carrying Capacity: Prevents abrasion and adhesion of friction components under heavy or impact loads. Excellent Adhesion: Prevents lubricant loss at high temperatures, extending lubrication and protection time. Environmentally Friendly: Does not contain heavy metals or other harmful substances. Among them, WGG-40R(W) has a white appearance, ensuring clean and easy handling.

Application

Suitable for the lubrication of open gear systems with frequent start-stop operations, especially for the lubrication and protection of open gears in wind turbine yaw and pitch systems. Suitable for lubricating the gear meshing surfaces and slewing bearings of vertically installed open gear drive systems in industries such as power, mining, steel, chemical, and port operations, including rotary reclaimers, large electric shovels, and port cranes. Capable of providing lubrication and protection for gears in high-saline environments such as coastal areas and offshore wind turbines, with good compatibility with automatic lubrication systems.

产品介绍

Product Overview

WGG-40R/WGG-40R(W) Wind Turbine Open Gear Grease is a high-performance specialized lubrication product designed based on the operational conditions of the yaw/pitch gear rings of large wind turbine and their special lubrication protection requirements. It uses carefully selected high-viscosity base oils and specially formulated metal soap as the thickener, supplemented with various high-performance liquid and solid additives. This grease meets the lubrication and protection needs of open gear rings under harsh operating conditions such as frequent starts and stops, heavy load vibrations, and varying open environments like wind, sand, and humidity.
