Castrol Optigear BM 320 High Performance Gear Oils
Castrol Optigear BM is a range of high-performance extreme pressure gear oils, developed to tackle wear-related problems in heavily loaded industrial gears and bearings.
Castrol Optigear BM 320 is formulated with Castrol’s Microflux Trans (MFT) Plastic Deformation (PD) additive. MFT PD helps improve performance when operating temperature and loads reach a certain level of activation energy, by enabling the micro smoothing of surface roughness without increasing wear.
The smoothed surface delivers optimum wear protection and an extremely low coefficient of friction, especially in applications which experience extreme pressure, shock loads, vibrations or low speeds.
MFT PD helps to protect against scuffing and shock loading, while maintaining a high load carrying capacity, and can help prevent the progression of micro-pitting in pre-damaged gears.
Specific grades within the Optigear BM range meet the requirements of DIN 51517 part 3 CLP and the requirements of a wide range of industrial bodies and equipment manufacturers.
Optigear BM 68 and BM 220 are also classified as CGLP oils (DIN 51502).
Castrol Optigear BM 320 is suitable for gears and bearings operating under normal to extreme conditions.
Extreme pressure additives make Optigear BM suitable where there is a need to maintain high load-carrying capacity while protecting against scuffing and shock loading.
Optigear BM 68 and BM 220 can also be used as slideway oils subject to a metalworking fluid compatibility check.
Compared to conventional non-PD oils, Castrol Optigear BM 320 can deliver the following advantages:
- Tests have shown a reduction in the coefficient of friction of up to 60% over conventional oils without PD technology which can deliver energy savings, lower lubricant and component temperatures and improve operational efficiency
- In laboratory tests, Castrol PD additives were shown to prevent the progression of micro-pitting in pre-damaged gears. Non-PD oils used in pre-damaged gears showed existing wear levels increased up to three times.
- Smoothing existing gear damage reduces the cost of repairs and replacements and improves operating efficiency by increasing equipment reliability
- Friction, heat and vibration are reduced
- Oil with Castrol PD additives provides superior protection with wear levels of less than half those observed in tests with conventional non-PD oil³ to help extend planned gear and bearing life
- Extended lubricant service life and relubrication intervals can help to reduce costs and waste oil disposal
- Full load operation is achieved in a short time, virtually eliminating the running-in period
- Optigear BM 68 and BM 220 CGLP slideway oils. (Subject to metalworking fluid compatibility check).
