All You Need To Know About EP 68 Gear Oil

Gear Oil EP 68 high-quality paraffin-based oil, comes with sulfur-phosphorus EP additives. This gear oil can reduce wear on gears operating under heavy loads and continuous shock conditions.

Additionally, they offer great gears of lubrication under shocked loads and heavy loads controlled by fractional motors.  Nevertheless, to know more about this topic read attentively.

Uses Of EP 68 Gear Oil

Uses Of EP 68 Gear Oil:

EP gear oil is suggested for use in industrial applications where you need to use EP gear oil. Additionally, they are non-corrosive to bearing tools and gears like copper, steel, brass, babbitt, bronze, etc. If the OEM prohibits EP additives, you can use this gear on worm gears.

These gear oils acquire skills in heavy lubricating loads under shock loads and extreme pressure. You can use this EP 68 Gear oil for spur gears, helical gears, bevel gears, and various gears.

Also, they are effective in lubricating contract mining, contract equipment, cement works, rolling rollers, ball mills, crushers, crushers, etc. This EP 68 gear oils are suitable to use in inches, Hoists, Vibrator Conveyors, Dump Winches, Ovens, Machine Tools, etc.

More applications include lubricating the sprockets, plain, chain drives, and anti-friction bearings. And you can use this oil successfully as a back-bearing lubricant and mist oil.

EP 68 Gear Oil Equivalent

The EP 68 gear oil has some similar quality EP gear oil equivalent. Nonetheless, There are Chevron Meropa 68, Mobilgear 600 XP 68, Phillips 66 extra duty gear oil 68, and Shell Omala S2 GX 68. This equivalent provides corrosion protection, oxidation stability, load-carrying capacity, etc. So, you can use this high-quality gear oil as an EP 68 gear oil equivalent.

What Is EP Gear Oil?

EP gear oils reduce wear and scuffing in industrial and automotive applications under high-load conditions.

You can especially use it where high peak or shock loads are encountered. Usually, current EP gear oils come with additives that contain active sulfur, often combined with phosphorus. Even so, it offers a non-corrosive, thermally stable lubricant with high-load carrying capability.

Accurate EP gear oil analysis is essential to ensure the correct amount of additives is present in the finished product formulation. Yet, it also can monitor the in-use condition of the active agent. Likewise, it may be essential to value the additive performance under particular conditions in used oil analysis.

 That’s why it’s necessary to understand the chemistry of EP gear oil, EP gear oil application, and the analytical materials used to measure the additive conditions.

150 220 EP Gear Oil:

EP 150 220 gear oil viscosity provides lead-free high-pressure type lubricants. Typically, these oils are mixed from a premium-quality base stock to provide extreme pressure and anti-wear properties. Notably, they are incredible for corrosion and rust control, good water separation capability, and high-temperature stability.

Hypoid Gear Oil:

All cars need gear oil to lubricate axle differentials and transmission. Unlike regular motor oil, the viscosity of gear oil is usually much higher to help combat the possibility of extreme conditions. It can produce a thinner fluid and allow the gears to grind against each other.

According to design, Hypoid gearsets are under more stress than other categories of gearsets. A sliding action is introduced by combining the rotational motion with a hypoid gearset absent in different designs.

In particular, this increased pressure and sliding action can force the gear lubricant out from between the meshing gear teeth. As a result, there will be metal-on-metal grinding.

Hypoid gear oils can help protect these particular types of gear sets. Hypoid gear oil may have the same high viscosity as other gear oils. But hypoid gear oil includes certain high-pressure and anti-wear additives. Moreover, it can enhance resistance to breakdown under high temperatures.

When to Use Hypoid Gear Oil?

As with all fluids, regular maintenance and changes of hypoid gear oil can expand the vehicle’s life and performance. Well-lubricated gears are less likely to pit, break, or grind against each other under stress.

Regular gear oil changes remove worn tools and other potential pollutants like water and dirt. If you don’t change this oil, it causes accelerated wear due to debris and possible rust from oxidation byproducts.

75W140 Gear Oil:

75W-140 gear oils mix with a high-quality synthetic base stock. Mainly, this gear oil helps offer low-temperature fluidity during low-temperature axle and transmission startups for lubrication. Similarly, it helps maintain a protective and thick oil film during hot conditions.

75W-140 comes with essential performance additives for outstanding protection of bearings and gears. These oils have extreme pressure agents to protect against shock loading and wear with specific corrosion inhibitors.

Oxidation inhibitors are incorporated to develop the oxidation stability of this synthetic oil. As a result, it makes lubricants with extremely long service life and sludge structures during high-temperature operation.

What Is 75w140 Gear Oil Used For?

Gear oil 75W-140 is commonly used as the rear axle oil for passenger vehicles and trucks with high loads. High-viscosity base stocks protect gears by maintaining oil film to the high-pressure agents used to lower metal-to-metal wear. Many 1-ton trucks utilized in trailer towing can take advantage of this gear oil.

FAQ ( Frequently Asked Questions):

Q. What is ISO 68 gear oil?

Hydraulic 68 is Crown Oil’s parts range of mineral-based premium-grade hydraulic oils. Therefore, it provides the most demanding system protection while meeting ISO standards. In contrast, this fluid can inhibit corrosion, rust, and oxidation.

Q. What oil should I use for my gearbox?

The most standard GL ratings are GL-5 and GL-4. GL-4 is generally used in regular vehicles for daily use. Hence, GL-5 is suitable for high-pressure gearboxes in high-power output vehicles and trucks. Your vehicle’s owner’s manual must state the correct GL rating for the transmission.

Q. What is non-EP gear oil?

Non-EP gear oil comes for use in several gear applications. They offer a long oil life with excellent oxidative stability, lubricity, film strength, and wear protection. Remarkably, they also provide outstanding protection in the most demanding applications.

Final Word

In summary, EP 68 gear oil is an industrial gear oil with a kinematic viscosity. Ultimately, this gear oil is manufactured from a mix of solvent mineral oils. For that reason, you can use this 68-gear oil in a broad range of geared systems. Overall, this oil is suitable for any geared system.
