Bel-Ray’s Synthetic Gear Oil 680 has received OEM approval from Komatsu for the products’ use in the electric motors on its mining and construction equipment, including its range of mining trucks and shovels. Bel-Ray stated: “This high performance, fully synthetic hydrocarbon and ester combination oil is authorised for use in General Electric GDY85, GDY106 and GDY108 electric wheel motors. Ideal for applications such as mobile equipment electric wheel motors and planetary transmissions found on electric mining shovels, this enclosed gear lubricant also carries General Electric OEM approval for general wheel motor usage with both AC and DC units.”

Bel-Ray Synthetic Gear Oil 680 has a number of key attributes according to the company:

• Extreme pressure properties – “Outstanding” anti-wear and extreme pressure capabilities provide a superior level of gear and bearing protection, under both normal and high load conditions, as proven with field evaluations
• Micropitting prevention – Often considered the root cause of premature gear failures, micropitting begins in the early stages of gear life and quickly progresses to macropitting. By preventing micropitting from the beginning, Bel-Ray Synthetic Gear Oil eliminates untimely gear failure and extends equipment life
• Thermal stability – Demonstrating “excellent” viscosity-temperature properties, this oil will not break down at elevated operating temperatures, providing an excellent lubricant film and preventing the formation of undesired sludge and varnish
• Filterability – This oil is highly filterable ― to the 10-micron level recommended by Komatsu ― and promotes maximum lubricant effectiveness by eliminating contamination-related wear, while also extending drain intervals.

“In fact, the superior thermal stability and filterability of this gear oil results in drain interval extensions of up to three times that of other synthetic oils,” said Don Howard, New Product Innovation – mining at Bel-Ray. “This maximises the cost effectiveness of this premium quality, enclosed gear lubricant for our customers.” In addition to the Komatsu and General Electric approvals, Bel-Ray Synthetic Gear Oil 680 carries OEM approvals from Liebherr and Flender. This product also meets or exceeds the requirements of numerous industry standards.
