Gear Oil for Gear Bearing and Circulating Systems
This synthetic gear oil meets ISO 150 and SAE 90W specifications for gear, bearing and circulating systems. The pail holds 35 lb of yellow lubricant and carries U.S. Steel 224, AGMA 9005 and DIN 51517 Part 1, 2, 4 approvals. It suits maintenance teams and plant engineers who need a single fluid for multiple enclosed gearboxes and circulating reservoirs.
Operating Range and Capacity Limits
The fluid operates from 0 °F to 195 °F with a viscosity index of 114, a flash point of 268 °F and a pour point of -43 °F. These limits give reliable film strength in normal industrial ambients but will not protect equipment that sees sustained temperatures above 195 °F or requires extreme-pressure additives. The 35 lb pail covers several refill cycles on small to mid-size gearboxes but falls short for large central systems needing drum or tote volumes.
Replaces Conventional Non-Synthetic Gear Oils
Switching from mineral-based gear oils to this synthetic base stock extends drain intervals and reduces deposit formation in gear and bearing compartments. The upgrade pays off where operating temperatures approach the upper limit or where longer service life cuts planned downtime. It is not suited for applications that demand NSF-rated food-grade lubricants or formulations with dedicated extreme-pressure additives.

Questions about this item
Will this 150 ISO gear oil mix safely with mineral-based 90W oil already in my gearbox?
The product uses a synthetic base oil with no additives, so compatibility depends on the existing lubricant; a full drain and flush is recommended before switching.
How can I verify the oil is performing correctly after the first fill?
Check that operating temperatures stay between 0 and 195 degrees F and that the fluid maintains its yellow colour; the 114 viscosity index and 268-degree flash point indicate stable high-temperature behaviour.
What comes in the pail and do I need any extra fittings or additives?
The 35 lb pail contains only the synthetic gear oil; no additives are included and the standards U.S. Steel 224, AGMA 9005 and DIN 51517 parts 1, 2, 4 cover the lubricant itself, not dispensers or fittings.
