62 E&MJ; • JUNE 2014 www.e-mj.com COMPANY PROFILE-PAID ADVERTISEMENT Bel-Ray products have a reputation for being best in class when it comes to quality per- formance and innovative technology. The demands of current and next generation min- ing equipment mandates superior lubricants formulated to ensure the best protection and performance. Bel-Ray's top tier open gear lubricant: Molylube SF-100 Semi-Synthetic Open Gear Lubricant is designed to meet and exceed the most demanding applications and OEM spec- ifications. The value and performance of the product has been proven around the world in the most challenging and harshest environ- ments. The confidence and strong following SF-100 has in the mining community comes down to the simple fact that it reduces wear, extends component life and reduces total cost of ownership. Molylube SF-100 is a top tier grease-type open gear lubricant. There are seven grades of SF-100 formulated for application temperature range between -50°C and +50°C. Regardless of the grade, the same performance qualities are present: excellent load carrying capability, reduce wear, which reduces equipment operat- ing temperatures and energy consumption. A very recent case study helps illustrate the benefits of converting to SF-100. A Canadian mining customer expressed interest in evaluating SF-100 on two P&H; 4100XPC-AC rope shovels. The customer was experiencing rapid wear on the saddle block wear plates on these shovels. The goal of our project with this customer was to extend the service life of the saddle block wear plates by converting the customer to SF-100. We were confident that once we could demon- strate the superior performance of the prod- uct on these two shovels the entire fleet of shovels would be converted. In order to conduct proper testing, new sad- dle block wear plates were installed and the rope shovels were properly converted. The con- version process included ensuring there were no compatibility issues with the existing open gear lubricant, pre-lubing the components with SF-100, and introducing the SF-100 into the centralized lubrication system. Once the shov- els were back in operation, SF-100 quickly established a heavy and durable lubricating film on all parts and assemblies, including the saddle block and dipper handle assemblies. The shovels in question have far exceeded the upper limit of the operating hour range at which the mine had been routinely changing the excessively worn wear plates. Wear rates of the wear plates have been significantly reduced. We invited the original equipment manufacturer out to inspect and provide their opinion on the performance of the SF-100 related to their rope shovel. The concluding comment of the OEM representative was that overall lube performance was excellent and wear rate is significantly improved after con- verting to the Bel-Ray product. This customer was previously changing out wear plates every 800-1,200 hours. Bel-Ray customers around the world have achieved wear plate change intervals at 8,000-12,000 hours. The test is ongoing, however, we are confident that we will see a massive increase on wear plate life based on proven performance we have experi- enced in the field. It speaks volumes that just a few months into our testing the customer converted their entire rope shovel fleet to the Molylube SF-100 Semi-Synthetic Open Gear Lubricant based on the results and perform- ance they had observed.
