Why should the bearing be lubricated?
- Mar 02, 2017 -

<1> Reduce friction and wear.

In contact with the ferrule, rolling body and the holding part of the bearing, to prevent metal contact, reduce friction, wear.

<2> Extended fatigue life.

Bearing rolling fatigue life, in the rotation, the rolling contact surface lubrication is good, then extended. On the contrary, the oil viscosity is low, the thickness of the lubricating oil film is not good, then shortened

<3> Exhaust frictional heat, cool.

Circulation to oil and so on can be carried out by oil from the heat generated by the friction, or by the external heat, cooling. To prevent the bearing overheating, to prevent the aging of lubricating oil itself.

<4> Others also have the effect of preventing foreign matter from intruding into the bearing, or preventing rust and corrosion.
