Double row angular contact ball bearing cages use double row angular contact ball bearings for stamped steel cages without the suffix of the cage.
The use of machined brass solid cages guided by steel balls is indicated by the most M. The suffix MA refers to the use of brass solid cage bearings guided by the outer ring. The glass fiber reinforced polyamide 66 cage (suffix TVH or The bearings of TVP) can be used for the stable temperature below 120 °C. If the bearing is oil smooth, the additives in the oil can shorten the service life of the cage. Others; oils aged at high temperatures can also shorten the use of bearings. Life; therefore it is necessary to strictly abide by the rules of the oil change cycle.
Under the operating conditions of the appropriate speed; the bearing speed can be higher than the reference speed; but can not be higher than the limit speed. When determining the hot speed, the impact of the special operating environment should be fully considered.
Heat treatment FAG double row angular contact ball bearings can be operated below 150 °C. If the cage uses polyamide data, the operating temperature is subject to the cage constraints. Sealed bearings are also subject to seal requirements.
Sealed bearings in addition to open double row angular contact ball bearings; double-sided with ZR type dust cover (non-touch seal) and double-sided with RSR type seal (touch seal) angular touch ball bearings are also supplied by FAG The basic layout. This kind of bearing has been filled with high-quality smooth grease tested by FAG in the manufacturer. If required, it can also be supplied with single-sided sealed bearings. Non-touch sealed bearings (suffix. 2ZR) are used. The limit speed is lower than the open bearing.

An Infrared Thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device's ability to measure temperature from a distance. By knowing the amount of infrared energy emitted by the object and its emissivity, the object's temperature can often be determined within a certain range of its actual temperature. Infrared thermometers are a subset of devices known as "thermal radiation thermometers".
