Castrol Optigear BM 100
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. Optigear BM 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 microsmoothing 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.
Application
Optigear BM 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.
Advantages
| •Tests have shown a reduction in the coefficient of friction of up to 60% over conventional oils without PD technology, delivering energy savings, lower lubricant and component temperatures and improved operational efficiency |
| •In laboratory tests Castrol PD additives were shown to prevent the progression of micro-pitting in pre-damaged gears |
| •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 oil, helping to 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 |
| •Miscible and compatible with unleaded gear oils based on mineral oil; compatible with non-ferrous metals, paints and conventional sealing materials |
