SAPPHIRE Dynamic high-performance grease

Designed for engineers who demand nothing less than peak performance

Meet SAPPHIRE® Dynamic – Built for Extreme Conditions

Engineered with Calcium Sulphonate technology, SAPPHIRE® Dynamic delivers extreme pressure resistance, exceptional water washout protection, and high thermal stability—operating at 180 °C (200 °C intermittently) without grease breakdown. Its superior oxidation resistance significantly extends lubrication life and helps reduce downtime. By preventing metal-to-metal contact and forming a self-renewing protective film, it ensures smoother operation and prolonged bearing life in the toughest industrial environments.

Pellet Mills

Load-bearing performance – SAPPHIRE Dynamic provides superior film strength, reducing metal-to-metal contact in heavily loaded pellet press roller bearings and minimising wear under extreme pressures.

Adhesion and mechanical stability – The inherent tackiness of SAPPHIRE Dynamic ensures strong adhesion to bearing surfaces, preventing grease displacement and maintaining consistent lubrication despite water washout and continuous impact forces.

Thermal stability – Relies on inorganic calcium carbonate, which remains stable regardless of temperature fluctuations or oxidative stress.

Steel Manufacturing

Natural extreme pressure resistance – SAPPHIRE Dynamic is particularly well-suited for Spherical Roller Bearings due to its shear-resistant structure, ensuring the grease remains intact despite continuous compression and movement within the bearing.

Water and corrosion resistance – The formulation of calcium sulphonate thickeners repels water, preventing emulsification and grease breakdown.

Thermal stability – Calcite remains stable even at high temperatures, ensuring consistent extreme pressure performance over a wider temperature range.

Paper Manufacturing

Water washout resistance – Exhibits minimal mass loss, meaning it retains almost all its lubricating film even under prolonged water exposure.

Shear stability – Due to its shear-resistant structure, SAPPHIRE Dynamic remains intact despite continuous compression and movement within the bearing, maintaining consistency and lubricating properties over extended periods of operation.

Extreme temperature performance – The natural lubricating properties of calcite provide continuous extreme pressure (EP) protection across varying temperature conditions, ensuring reliability in paper manufacturing processes.

Heavy Industry

Superior oxidation resistance – SAPPHIRE Dynamic benefits from a highly stable sulphonate structure combined with an overbased calcium carbonate system, ensuring oxidative stability lasts more than twice as long compared to alternative greases.

Prevention of scuffing & galling – Under severe pressure, calcite fills in microscopic imperfections on metal surfaces, forming a self-renewing protective film that prevents surface welding and material transfer.

Resistance to mechanical shear & grease breakdown – SAPPHIRE Dynamic provides exceptional mechanical stability, ensuring that consistency and effectiveness are maintained over long operational periods, even heavily loaded bearings.

What makes SAPPHIRE Dynamic different from other industrial greases?

SAPPHIRE Dynamic is a calcium sulphonate complex grease designed for extreme pressure, high load, and high-temperature applications. It offers superior mechanical stability, extreme pressure resistance, and exceptional water washout protection. Its natural lubricating properties form a self-renewing calcite film, reducing metal-to-metal contact and minimising wear. Additionally, it maintains performance under thermal stress and shear forces, ensuring long-lasting lubrication in demanding environments such as steel manufacturing, pellet mills, and heavy industry. Its compatibility with lithium-based greases also makes it easier to transition without operational disruptions.

Is SAPPHIRE Dynamic suitable for any specific industrial applications?

Yes, SAPPHIRE Dynamic is engineered for extreme conditions in industries where conventional greases may fail. It is particularly effective in steel manufacturing, pellet mills, paper production, and heavy industry due to its exceptional load-bearing capacity, shear stability, and water resistance. In pellet mills, it reduces wear on heavily loaded roller bearings. In steel manufacturing, it provides long-lasting lubrication for spherical roller bearings under extreme pressure. In paper manufacturing, it resists water washout, maintaining lubrication in high-moisture environments. Additionally, its high thermal stability and mechanical strength make it ideal for heavy industrial applications where consistent performance is critical.

How does SAPPHIRE Dynamic reduce costs?

SAPPHIRE Dynamic extends equipment life and reduces maintenance costs by providing superior protection against wear, extreme pressures, and water washout. Its exceptional mechanical stability ensures longer re-greasing intervals, minimising downtime and labour costs. In harsh industrial environments, where bearing failures can lead to costly repairs and production halts, SAPPHIRE Dynamic helps prevent breakdowns by maintaining a durable lubricating film. Additionally, its high resistance to oxidation and thermal degradation means less grease is needed over time, reducing overall consumption.

By using SAPPHIRE Dynamic, engineers can also consolidate their grease inventory, replacing multiple lubricants with a single high-performance solution suitable for a wide range of applications, further streamlining maintenance and reducing costs.

How can I purchase SAPPHIRE Dynamic?

Is SAPPHIRE Dynamic compatible with Lithium base greases?

SAPPHIRE Dynamic is compatible with lithium-based greases, including lithium, lithium-12 hydroxy, and lithium complex types. This compatibility arises from the chemical similarities between calcium sulphonate complex and lithium soap thickeners, allowing them to function effectively when combined. Historically, lithium and calcium soaps have been compatible with each other. However, while these greases can be mixed, we recommend contacting us for expert guidance to ensure optimal performance in your specific application.
