Spec Oil 460 Grease
Spec Oil SHCT Grease 460 is superior performance grease is designed specifically for severe paper machine applications, including extreme temperature environments and exposure to different qualities of water. Spec Oil SHCT Grease 460 combine the unique features of a synthetic base fluid with those of a high quality lithium complex thickener.
- The wax-free nature of the synthetic base fluid provides excellent low temperature pump ability and low starting and running torque compared to other non-synthetic oil products of the same viscosity.
- The high viscosity index of the synthetic base fluid ensures excellent film protection at high temperatures.
- The lithium complex thickener contributes excellent adhesion, structural stability and resistance to water.
These properties are complemented by a special additive system to provide:
- rust and corrosion resistance,
- wear protection,
- thermal/oxidative resistance and
- to enhance water resistance properties.
Spec Oil SHCT Grease 460 is a NLGI grade 1.5 with base fluid of ISO VG 460.
Spec Oil SHCT Grease 460 is designed for use in the most critical rolling element bearing applications in paper machines. They provide outstanding protection against rust and typical acid and alkali water corrosion, making them ideal for the wet end of the paper machine. The low volatility and excellent oxidation stability of the PAO base stock ensures excellent service at high temperatures typical of dry end conditions.
Spec Oil SHCT Grease 460 has become the technology of choice for many paper mill operators, worldwide. Its reputation is based on exceptional quality, reliability and the proven performance benefits they deliver.
Spec Oil SHCT Grease 460 symbolizes our continued commitment to using advanced technology to provide outstanding products. Spec Oil SHCT Grease 460 is recognized and appreciated for their innovation and outstanding performance. A key factor in the development of Spec Oil SHCT Grease was the close contacts between our scientists and application specialists with key paper machine designers to ensure that our product offerings would provide exceptional performance in this continually evolving, and increasingly severe, equipment area.
Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Spec Oil SHCT Grease 460.
These benefits include:
- excellent resistance to acidic and alkaline water,
- enhanced bearing protection and bearing life,
- wide temperature range of application,
- and longer grease life.
To combat high thermal exposure our product formulation scientists chose proprietary synthetic base oils for Spec Oil SHCT Grease 460 because of their exceptional thermal and oxidative resistance. Our scientists developed a high performance lithium complex thickener technology and used specific additives to enhance Spec Oil SHCT Grease 460 to meet the needs of modern and future paper machines. Spec Oil SHCT Grease 460offer the following features and benefits:
While Spec Oil SHCT Grease 460 is compatible with most mineral oil based products, admixture may detract from their performance. Consequently it is recommended that before changing a system to Spec Oil SHCT Grease 460, it should be thoroughly cleaned out to achieve the maximum performance benefits. If dismantling the system for cleaning before changeover isn't feasible, then thorough purging and increased re-lubrication intervals are strongly recommended.
Spec Oil SHCT Grease 460 is recommended for critical rolling element bearing applications in paper machines.
Included among these are:
§ Highly loaded press section bearings.
§ High-temperature felt roll and calendar stack bearings
§ Wet end paper machine bearings
