ENDURATEX™ Synthetic EP Gear Oils


ENDURATEX Synthetic EP gear lubricants are premium performance, extreme pressure lubricants designed for enclosed industrial gears and bearings operating under severe load conditions and in wide extremes of temperature.

  • Do I need to buy all my stock from you?
    We’d love it if you did, but no, you don’t have to order all your lubricants from us. Some customers jump in with two feet and consolidate all their lubricant stock into the EziStock system, while others like to dip their toes in first and start with a selection of lubricants and add to it as they see fit. As with any ordering situation, the lubricants we supply is completely up to you. Only items approved by you will ever go into the system, so you won’t be finding any surprises on your monthly invoice. If you’re not wanting to keep all your eggs in one basket, you’re perfectly entitled to keep purchasing from other suppliers as well, however only EziStock items are to be kept in the EziStock storage to enable the replenishment cycle to run smoothly.
  • What happens if I reassess pricing down the track and find its cheaper with another supplier?
    It’s great to keep your finger on the pulse and be aware of all your options to make sure you’re getting the best value for your business. With EziStock you are free to add or remove stock items from the system at any time, so should you want to switch an item to another supplier you can. While it can be tempting to jump over to another supplier offering a slightly cheaper price for a product, the EziStock system also provides savings in another way, and that’s in terms of the time savings of not having to manage stock and place orders. When you include the labour cost of stock management to your product purchase cost, customers often find it would cost them more to make the switch. Of course, if you simply find the system is not for you, that’s absolutely fine. There’s no locked in contracts, and if you want it out, we’ll take it out. No questions asked, and no hard feelings.
  • Who are your replenishers?
    Our national onsite inventory replenishment team are locally contracted individuals whose sole responsibility is to count the stock, tidy and replenish. They’re not part of the sales team, they’re just a friendly bunch of folks keen to get the job done efficiently. Outside of the replenishment, we have a dedicated EziStock operations manager who does all the behind-the-scenes work including training and managing the local replenishers, organising and processing monthly EziStock orders, and adjusting stock where requested. He’s also likely to be the friendly face you’ll see setting up your EziStock storage facilities when they get installed.
  • How can we keep control if you take over stock management?
    It’s completely understandable that the prospect of handing over your stock management to a supplier can be a little daunting. In running your operations, you want to have control, and the good news is, you still will. EziStock is not about handing over control to us. Throughout the entire process everything is checked and approved by you. Nothing goes into the system without your consent, and reporting allows you to see exactly what is being used and charged for each month – the system is very transparent.
  • What if we already have a preferred supplier we like to buy from?
    There’s no doubt about it, we’re a supplier and we want your business. EziStock is a system developed for businesses looking to get the best bang for buck both in terms of the consumables they’re purchasing, but also in enabling better efficiencies and therefore productivity in the workshop. If you have another supplier you prefer to work with, that’s fine, it’s completely up to you – no hard feelings.
  • What happens if EziStock doesn't work for us?
    If the solution simply isn’t working for you, we can remove it. No worries, no hurt feelings. There’s no locked in contracts, and at the end of the day, if the solution isn’t benefitting you, it’s not benefitting us. It has to save you time and money.
  • What’s in it for Duramach? What’s the catch?
    There’s no catch. EziStock is a fully open, transparent solution, with reporting so you can see exactly what’s going on. What’s in it for us? Well we’ve got everything to gain by looking after you and your business. Duramach is not a one off sale, it’s having a loyal customer in 10 years time that we’re able to continue providing value for. Basically, your success is our success.

ENDURATEX Synthetic EP premium performance lubricants are recommended for enclosed industrial gear drives and bearings particularly where they are operated under heavy duty conditions such as heavy loading, slow speed, shock loads and in wide extremes of temperature.

The tough oil film and low coefficient of friction save energy in gearboxes. The high viscosity index of ENDURATEX Synthetic EP oils mean they retain their viscosity at high operating temperatures. This often allows the use of a lower ISO grade than with conventional gear oil, resulting in even greater energy savings.


The ENDURATEX Synthetic EP line is designed to combat high temperature conditions and will run cooler while maintaining exceptional lubricant film strength. For gearboxes that operate outdoors, selected ISO grades of ENDURATEX Synthetic EP oils are capable of operating at temperatures as low as -30°C (-22°F) or below.


When converting a gearbox to ENDURATEX Synthetic EP, it is recommended it be cleaned and flushed first to gain the full benefit of the product. ENDURATEX Synthetic EP oils are compatible with mineral oils, polyalphaolefin lubricants and most seal materials except natural rubber.

The ENDURATEX Synthetic EP oils operate over the temperature range from -30°C (-22°F) to 121°C (250°F).


ENDURATEX Synthetic EP oils are designed to meet the following OEM standards:

  • DIN 51517-3-August 2011

  • Approval for Flender Gear Units

  • Eickhoff Gear

  • Jahnel Kestermann

  • AIST 224 (formerly US Steel 224)

  • AGMA 9005-E02 (EP)

  • David Brown S1.53.101 Type E
