HF 0812 bearing belongs to the specification of needle roller bearing

Hf 0812 bearing belongs to the specification of needle roller bearing -- punch outer ring needle clutch bearing HF series
12 mm diameter
The thickness of 12 mm
Hf 0812 bearing characteristics:
The punch outer ring needle roller clutch bearing hf 0812 is a unidirectional clutch composed of a thin-walled punch outer ring, a plastic cage, a spring and a needle roller with a series of oblique raceways on its inner diameter;
Can transmit unidirectional torque;

Has a particularly small radial section height;
The spring's holding force on needle rolling ensures constant contact between shaft, needle rolling and oblique raceway;
Allows high conversion frequency
Because the mass of the clamping parts is small and the relevant inertia moment is small;
With small air friction moment;
Easy to install;
Bearing hf 0812 pressed into the bearing seat hole;
No further axial positioning is required;
Can be used in combination with HK and BK series stamped outer ring needle roller bearings.
Damage reason for hf 0812:
In general, 33.3% of needle bearing hf 0812 damage is due to fatigue damage, 33.3% is due to poor lubrication.
dust.

Clean hf 0812 bearings and the surrounding environment, fine dust invisible to the naked eye is a strong killer of bearings, which can increase the wear, vibration and noise of bearings.
The impact of non-professional tool installation
The use of suitable and accurate equipment and things as far as possible to use special things, can try to avoid the use of cloth and short fiber and other things.Needle roller bearings whether in the laboratory test or in practice, it can be clearly seen that the appearance of the same needle roller bearings under the same operating conditions, the actual life of it is very different.
