Detailed Photos
Our company provides high-precision homemade bearing of ordinary material, including deep groove ball bearing and full complement cylindrical roller bearings.
The material refers to high-quality bearing steel, thermal treatment technology is put under strict control, and it is able to carry out cryogenic treatment. And full complement cylindrical roller bearings adopts advanced roller furnace for thermal treatment. Other technologies are all processed by full-automatic and semiautomatic equipment, and the production technology and quality control are arranged as per P5 precision. It products widely support home and abroad manufacturers of electric tools, mechanical equipment, automobile components, etc.
Commonly used to adjust the full complement cylindrical roller bearings radial clearance as follows:
1, cylindrical and oval bearing backlash, can be manually scrape or bearing equatorial plane after turning padded scratch repair method of adjusting.
2, cylindrical and oval bearing the headspace, can be hand-scrape method or circumstances permit bearing the equatorial plane padded adjustments.
3, for more oil wedge fixed bearing, in principle, allow repair scratch and adjust the bearing clearance, the gap should be replaced with new tile inappropriate.
4, for more oil wedge tilting bearing, does not allow repair scratch pad, the gap should be replaced due to inappropriate tile. The thickness of the adjustable tile, tile can be adjusted by the amount of the adjustment in the next block behind tile plus stainless steel pad, thickness or thinned adjustment block approach. Note for more oil wedge tilting bearing, among the same group of tile thickness error should be less than 0.01mm.
Note issue
Vibration aspects
In normal use, the vibration of the bearing damage is very sensitive, peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the bearing vibration measurement. So, through the use of special bearing vibration measurement device (frequency analyzer, etc.) to measure the size of the vibration, the frequency distribution can be inferred by abnormal circumstances. The measured values due to the use of conditions or bearing sensor installation location, etc., and thus requires prior to each machine measurements were determined after analysis and comparison criteria.
Terms of temperature
High temperature frequently expressed cylindrical roller bearings are in an abnormal situation. High temperature is also harmful to the bearing lubricant. Sometimes bearing overheating can be attributed to the bearing lubricant. If the bearing temperature over 125 ºC even move to reduce long-term bearing life. Causes high temperature bearings include: lack of lubrication or excessive lubrication, bearing raceways containing impurities, the speed limit is too high, bearing long-term overload and so on.
