☆ Main technical indicators
1 Suitable for : cylindrical roller bearings , tapered roller , etc.
2 Size : Φ5.5mm ~ Φ48mm
3 material: ferromagnetic
4 detection speed : 60 / min
5 detection sensitivity : the roller surface roughness Ra ≤ 0.32μm conditions under artificial notch 2.5mm × 0.05mm × 0.1mm ( length × width × depth )
6 Automatic sound and light alarm , sorting
7 points from the ratio of the differential probe
8 Power :. 220VAC, 50Hz
9 Ambient temperature :. -10 ° C ~ +40 ° C
Oil capacity: approximately 30% of free space inside the bearing .
When grease lubricated bearings start , may occur once the temperature peaks. Therefore, the bearing may need to run 10-20 hours before reaching normal operating temperature .
Under these particular conditions, the lubrication oil and grease lubrication is equal to the reference speed.
In the case of the bearing outer ring rotates , it may be necessary to reduce the rating.
For some bearing , their speed limits than by rolling element / raceway contact surfaces bearing a decision table bearing only their speed limit value. These bearings include classes of bearings with contact seals .
Speed ??limit
The speed limit is determined by a certain standard . These standards include the bearing cage shape stability and robustness , maintaining lubrication, rolling withstand the centrifugal force and the swing frame rail surface , as well as other factors that limit the speed .
Laboratory tests and practical experience show that the bearing should be insurmountable maximum operating speed ; This is for technical reasons, but also because you want to run another temperature is maintained at an acceptable level , the cost of which involve very high .
Speed ??limit values ??see table bearings , high-speed applications based on various requirements ; shown in this catalog bearings and cage design has taken into account this point.
Bearing may run at a speed higher than shown in the table , but this operation must be considered accurate and cage design , lubrication and heat dissipation problems.
Special circumstances
In some applications , more than the speed limit is more important factors to consider .
Low speed
At very low speeds , the hydrodynamic lubricating film flexibility possible and the contact surfaces of the rolling body raceway is formed . In these applications, the lubricant should generally contain EP additives. {HotTag}
Swing back and forth
In this operating state , the rotational direction of rotation when the bearing is not already full circle changes . Since the rotation speed is zero when the reverse rotation Fangxiang Gang , the lubricant is completely hydrodynamic lubricating film can not be maintained . In this case, in order to withstand the load to obtain a boundary lubricant film lubricant containing an effective EP additives are very important.
To set such a limit speed reciprocating or oscillating rated speed is not possible because it is not constrained by the maximum speed the heat balance , but rather determined by the inertial force associated . Each time the direction is reversed , there will be a danger , that is the force of inertia will cause rolling glide small distances , and to the raceway is dirty. Permissible acceleration and deceleration of the rolling elements and depending on the body weight of the holder , the type and dose of lubricant , and the operation of the load bearing clearance . For example , the bearing arrangement of the link , using a rolling body is relatively small , lightweight pre- loaded bearings. Unable to provide a general guide , but to specific circumstances , make more accurate motion analysis .
