1, manual lubrication
SKF bearings lubricant, timely fuel oil, which is the most primitive way. This method is difficult to maintain a certain amount of oil, negligence and forget the risk of fuel, usually only used for light-load, low-speed or intermittent motion of the occasion. Best dust cover on the filling hole or ball, blankets, cotton, wool and other filtration devices.
2, lubricating oil pad
The use of the capillary action of the oil pad coated with the lubricating oil of the oil sump to the surface of the shaft diameter. This friction surface can be kept clean, but the dust will cause clogged pores oil supply shortage. The oil supply amount of the lubricating oil cushion oil lubrication is usually only 1/20.
3, the oil ring lubrication
Lubrication method can only be used for the horizontal axis. Rely on a ring hanging on the shaft and can rotate the lubricant sump to the bearing. Suitable for medium-speed and high-speed SKF bearing shaft diameter greater than 50 mm. Oil ring is preferably seamless, bearing wide-diameter ratio of less than 2, only one oil ring, or need to use two oil ring.
4, splash bearings
By rotating parts in the tank slap splashed with oil supply SKF bearings for high speed bearings.
5, oil bath lubrication
The bearing part is immersed in the lubricating oil in the lubrication method. This method is commonly used in the vertical axis of the thrust bearing, and should not be used for horizontal shaft radial SKF bearings.
