FAG bearing lubricant inspection method

Apply a little bit of lubricant to the friction between the two fingers. If there is any contaminant, it can be felt. Or apply a lubricant on the back of the hand and then check the light.

FAG bearings lubricated with oil should be refilled with fresh oil and allowed to rotate at low speed for a few minutes if the old oil is drained. As much as possible, allow the oil to collect residual contaminants and then vent the oil. Note: It is best to filter the oil before use.

For grease-lubricated FAG bearings, when replacing grease, the cutter used should avoid any contact with cotton material in any part of the FAG bearing. Since these residual fibers may be wedged between the rolling elements and cause damage, especially the application of small bearings requires attention to this problem.

When inspecting FAG bearings, never expose the bearings to contaminants or moisture. If the work is interrupted, cover the machine with a piece of oil-paper plastic or similar material.

Questions about NSK bearing maintenance technology

When to change oil and how much oil should be changed. If the oil change is too small, the NSK bearing will be scrapped in advance; if the oil is changed too much, the NSK bearing will be in trouble or long-term damage to the power coil and the coil.

There is a simple precondition for the lubrication interval: to keep the equipment operating properly under conditions where the NSK bearing does not stop due to drying and collapse. This is a fixed concept of prevention. However, we must maintain a balance between lubrication and hunger and a lot of over-lubrication.

Traditionally, lubrication plans are based on time. Equipment suppliers typically develop lubrication plans based on operating time. And equipment suppliers often add guidance on the amount of lubricant during their maintenance planning.

For the staff, short-term lubricant replacement is very common, and often more grease is added. If the staff is required to change the lubricant every two to three weeks, add one ounce of grease each time. These suggestions started at the outset and they were built on factors that were not known in any practical sense.
