Thin walled bearings Advantage

Thin wall bearing a very thin bearing cross-section, and product miniaturization and lightweight. The diversity of products has expanded the scope of its use.

Thin walled bearings Classification

The thin-walled rings bearing high precision, very quiet, and strong carrying capacity. These ball bearings, there are three design, and the extreme small, most of the cross section is square. In these series, even if it is a larger shaft diameter and the bearing hole, the cross section also remain constant. These bearings are therefore referred to as the constant section.It is this characteristic that the thin standard ISO Series ferrule bearing and conventional bearing distinguish. Accordingly, it is possible to select a larger cross-section and use stronger bearing carrying capacity without changing the shaft diameter. The thin-walled rings bearing can be designed to be extremely light and need a small space bearing.

Thin walled bearings The purpose of lubrication

1,Reduce friction and wear
In constituting the bearing rings, rolling elements and a retainer of the mutual contact portions, to prevent metal to metal contact to reduce friction, wear. Extend the fatigue life of the rolling contact fatigue life, in rotation, the rolling contact surface of good lubrication, the extension. Conversely, the oil viscosity is low, the thickness of the lubricating film is not good, then the shortened.
2,Discharging the friction heat, cooling
Loop oiling method or the like can be oil discharge the heat generated by friction, or the heat coming from an external cooling. Prevent bearing overheating, aging prevent lube itself.
3,Other
To prevent the intrusion of foreign matters inside the bearing, or prevent rust and corrosion effects.

Thin walled bearings Lubrication method

Bearing lubrication method, divided into grease and oil lubrication.In order to make the bearing play function, first, to select the appropriate conditions of use, the purpose of the lubrication method. If only to consider lubrication, oil lubrication lubrication dominant. However, the grease around the bearing structure can be simplified expertise, compare the pros and cons of grease and oil lubrication.
