Gear Oil 100

Product Overview

SiNDA Gear Oil 100 is an industrial gear lubricant developed for enclosed gear and power transmission systems operating under moderate mechanical loads. It is designed to maintain a stable lubricating film between meshing gear teeth, helping reduce frictional losses and limit surface wear during continuous operation.

In many industrial environments, gearbox failures are linked to lubricant ageing, viscosity breakdown, or inadequate surface protection. Gear Oil 100 is formulated to address these risks by balancing viscosity stability, oxidation resistance, and corrosion protection—supporting reliable gearbox operation over standard service intervals.

 

Operational Applications

Gear Oil 100 is suitable for a wide range of enclosed industrial gear systems where consistent lubrication performance is required. Typical applications include:

• Enclosed spur and helical gearboxes
• Bevel gear systems
• Gear units using splash or circulation lubrication
• Plain and rolling bearings operating under moderate loads

In industrial gearbox practice, Gear Oil 100 is commonly selected for applications requiring a medium-viscosity gear lubricant, particularly where load conditions are stable and operating temperatures remain within standard industrial limits.

Technical Specifications

Selecting the correct technical parameters is critical to ensuring lubricant compatibility with gearbox design, operating temperature, and load profile. The specifications below define the intended operating window for Gear Oil 100.

• Nominal Viscosity Grade: ISO VG 100
• Lubricant Type: Industrial gear oil; confirm documented CLP performance
• Base Oil: Mineral-based formulation
• Additive Technology: Zinc-free, ashless system
• Operating Temperature Range: Confirm the permitted range in the current formulation TDS and gearbox manual

These parameters align with common industrial gearbox requirements and typical OEM recommendations for moderate-load, enclosed gear systems. Final operating limits should always be verified against specific gearbox manufacturer documentation.

 

Performance Characteristics

Load Carrying Capability

Gear Oil 100 provides reliable scuffing resistance and adequate load-carrying capacity for gear systems subjected to continuous, moderate loads, helping prevent premature gear tooth distress.

Wear Protection

The anti-wear additive system forms a protective boundary layer on metal surfaces, reducing direct metal-to-metal contact during start-up and steady-state operation.

Thermal & Oxidation Stability

Controlled oxidation stability helps slow lubricant degradation at elevated operating temperatures, supporting viscosity retention and surface protection over extended service periods.

Operational Outcome

Stable lubrication performance contributes to smoother gear meshing, reduced vibration, and improved overall gearbox reliability.

 

Compatibility & Limitations

Understanding where Gear Oil 100 performs best—and where it should not be used—is essential for protecting equipment and avoiding unnecessary maintenance risks.

Compatible With:

• Steel gear materials
• Multi-metal gearbox assemblies
• Standard industrial seals and elastomers
• Enclosed gear systems using splash or circulation lubrication

Not Recommended When:

• Gear systems are exposed to heavy shock loads or severe impact loading
• Contact pressures or load spikes exceed CLP gear oil performance limits
• OEM documentation specifies fully synthetic or high-EP gear lubricants

Practical Selection Rule:

If gear teeth show signs of scuffing, pitting, or abnormal load spikes, a higher-performance EP or synthetic gear oil should be evaluated instead of Gear Oil 100.

 

Selection Guidance

Choose Gear Oil 100 when:

• ISO VG 100 and the required documented performance category are specified
• Load conditions are moderate and continuous
• Operating temperatures remain stable within normal industrial ranges

Avoid Gear Oil 100 when:

• Equipment operates under severe, irregular, or shock loading
• Prolonged high-temperature exposure exceeds CLP performance limits
• Specific OEM approvals or synthetic formulations are required

Clear selection guidance helps reduce the risk of lubricant misapplication—one of the most common causes of reduced gearbox service life.

 

Compliance & Standards

Gear Oil 100 is identified as ISO VG 100. Confirm DIN 51517-3 (CLP), the relevant ISO 12925-1 performance category and any OEM requirements against current formulation documentation; viscosity classification alone does not establish performance approval.
Always confirm lubricant selection against OEM gearbox specifications prior to use.

 

Industrial FAQ

Is Gear Oil 100 suitable for circulation lubrication systems?

Yes. Gear Oil 100 can be used in both splash and circulation lubrication systems for enclosed industrial gear units operating within its recommended range.

Can Gear Oil 100 be used in bearings?

It is suitable for plain and rolling bearings where load and temperature conditions fall within the product’s intended operating window.

Why is a zinc-free formulation used?

The published description identifies a zinc-free, ashless additive system. Confirm this for the supplied formulation. Zinc-free chemistry alone does not establish compatibility with yellow metals, seals or another lubricant.
