Lubricating method of INA Bearings

1. Manual lubrication

INA Bearing lubricant oiler oil used in a timely manner, which is the most primitive method. This method is difficult to keep oil certain forgot to refuel dangerous negligence, usually used only for light-load, low-speed or intermittent motion occasions. Best set dust cover or ball valve on the filling hole, blankets, cotton, wool, etc. as a filtering device.

2. Oil pad lubrication

The oil pad the capillary action of the oil sump of the oil coated onto the surface of the major axis diameter. This method enables the friction surface is kept clean, but the dust will be clogged pores caused by insufficient oil supply. Usually only oil lubrication of the lubrication oil supply amount of the oil pad 1/20.

3. Oil ring lubricating

Only for horizontal shaft lubrication. By the hanging ring on the shaft and can be rotated to the lubricating oil of the oil pool to the bearing. Suitable for shaft diameter greater than 50mm medium-speed and high-speed INA Bearing. Preferably, the oil ring is seamless bearing wide diameter ratio of less than 2, only one oil ring, otherwise requires two oil rings.

4. Splash bearings

Rely on rotating parts in the fuel tank slap and splash oil supply INA bearings, suitable for high speed bearings.

5. Oil bath lubrication

The method will be partially immersed in the lubricating oil in the bearing lubrication. This method is commonly used in the vertical axis of the thrust bearing, and should not be used for horizontal shaft radial INA bearings.
