Oil+Air lubrication unit OLA
For use in oil and air lubrication systems
For tool spindles designed for high efficiency and long service life, we developed SKF Oil+Air lubrication systems. These systems provide a continuous, finely metered flow of oil that can be tailored to operating conditions by changing the metered quantity and the cycle.
A lubrication unit, a progressive or single-line metering device pumps a defined quantity of lubricant to a mixing valve. There, an air flow feeds the lubricant through the secondary line and to the lubrication point in the form of oil streaks. The bearing or chain is thus continuously supplied with a flow of lubricant and air. The air flow introduced creates overpressure in the bearing assembly and prevents the ingress of contaminants. This form of lubrication typically does not form an oil mist.
Oil-streak sensors continuously monitor the oil flow in the secondary line. Oil and air lubrication units can be configured individually for each application.
Features & benefits
- Better machining performance in spindle bearing lubrication due to higher speed factors (on spindle bearings, up to approx 2,5 × 106 mm × rpm)
- Higher dependability due to continuous supply of defined quantities of lubricant; sealing air provided by the system protects the bearings against outside contamination
- Less lubricant – as much as needed, as little as possible – for greater safety and environmental protection; demand-based metering for each lubrication point, with approximately 90% lower lubricant consumption compared to oil lubrication
- No oil mist, no repack period compared to grease lubrication
Applications
- Bearing lubrication, especially of spindle bearings
- Chain lubrication
- Gear train lubrication
- Slideway lubrication
- Assembly and process oiling
