Greyhound Circulating Oil 68 1L

Greyhound Circulating Oil 68 1L: rust-inhibited ISO VG 68 circulating oil

Greyhound Circulating Oil 68 1L is a rust and oxidation inhibited mineral circulating oil in the ISO VG 68 grade, supplied as one 1 litre bottle, the top-up and sample size. Greyhound developed the range for the conveyor and crusher bearings of copper crushing mills, because water, dust and scale get into the oil there every shift. As a result, the oil resists foaming, separates water quickly and protects steel against rust. In short, it keeps circulating systems clean and running for longer.

Every grade carries an ashless sulphur-phosphorus system with extreme pressure capability. Therefore one product covers both plain circulating duty (the CL class) and circulating systems that also lubricate loaded gearing (the CLP class).

Where Circulating Oil 68 1L excels

ISO VG 68 sits in the light band of the range. It suits turbine-type and R&O circulating systems, high-speed spindle and bearing circulation, machine tool circulating systems and combined hydraulic and circulating duty. VG 46 and VG 68 are the workhorses of this band. Typical duties include ball, cement and strip mills, conveyor bearings in mining, plain and rolling-element bearings in ferrous and non-ferrous mills, and any circulating system where water contamination is a problem. It suits ring-oiled, bath and pressure-fed systems alike.

Key benefits

• Rust and corrosion protection: inhibitors protect the internal surfaces of the system, even when water is present.
• Demulsibility: water separates out instead of forming an emulsion, so you can drain it from the reservoir.
• Anti-foam: the oil releases entrained air quickly, which in turn protects pumps and controls.
• Oxidation resistance: long oil life with little sludge or deposit formation.
• Extreme pressure and anti-wear protection: carries loaded gears and therefore extends the life of moving parts.
• High filterability: suitable for very fine filters and oil-mist systems, because it contains no lead compounds.

Applications

Ball mills, cement mills, hot and cold strip mills and plate mills. Conveyor bearings in mining applications. Plain and rolling-element bearings in ferrous and non-ferrous mills. Large, slow-speed bearings in mixers and mills. Combined hydraulic and circulating systems where design and maintenance keep leakage low.
