GRS-460-F Synthetic Grease
¡°Food Grade Applications¡±

GENERAL

GRS-460-F is part of a family of new high performance synthetic lubricants especially designed to meet the requirements of the food industry. For the first time, a truly high performance grease is available for applications with indirect food contact.
The growing trend to extend intervals between lubrication and the increasing use of sealed-for-life bearings impose increasingly stringent demands on grease performance. Service under temperature extremes, shock loading, vibration, and water wash conditions add to these demands. GRS-460-F Synthetic Grease is compounds with a polyalphaolefin (PAO) base fluid to provide extended service life and wide temperature range capability. Coupled with a high performance additive package, this new product is a real multi-purpose lubricant which can effectively handle a wide range of applications.
Authorized by USDA for use in Federally inspected meat and poultry plants.
Complies with FDA 21 CFR 178.3570 ¨C Lubricants with Incidental Food Contact.

FEATURES

Several outstanding performance features of GRS-460-F Synthetic Grease are:
* Wide operating temperature range
* Excellent low temperature torque characteristics, as low as -54¡æ(-65¨H) soft and serviceable to -62¡æ(-80¨H)
* Very high dropping point of 274¡æ(526¨H)
* Long bearing life at elevated temperatures and high speeds, provides long term lubrication at 204¡æ(400¨H)
* Exceptionally good resistance to oxidation and water washout
* Very good extreme pressure and antiwear properties
* Consistency maintained under extensive shearing
*The polyalphaolefin base fluid in this product is similar to mineral oils. Therefore, seal materials compatible with conventional petroleum products are also compatible with GRS-460-F Synthetic Grease.

APPLICATIONS
Because of its truly multi-service capabilities, GRS-460-F ¡±Food Grade¡± Synthetic Grease is suitable for lubrication of most anti-friction bearings over a wide range of temperatures and speeds where long retention, oxidation stability and resistance to the washing effects of water are necessary. This grease is also recommended for splines, screws, grease-lubricated worm gears and other mechanisms featuring steel-to-steel or steel-to-bronze surfaces. Additionally, it is recommended in bearing situations where oscillatory motion and vibration create problems.
