the country launched a series of policy for the machine tool industry vigorously support, industrial policy, import and export policy, tax policy has greatly promoted the rapid development of the machine tool industry in recent years continue to. LYDZC ADAPTS to this trend to improve the production equipment, improve the level of scientific research, to achieve mass production of YRT series bearings, at a lower price, better quality service host customers.
Bearing of YRTM series correspond in the double direction thrust cylindrical roller combined bearing YRT but are additionally fitted with a steel ruler, to control and adjust the double direction thrust cylindrical roller bearing rotation accuracy, and guarantee the machine high precision operation.

Abnormal running state of bearing and its reasons and countermeasures
The reasons and countermeasures for operation state prediction
Noise metal noise (1) abnormal load correction fit and bearing clearance, adjustment of pre-tightening, correction of bearing seat shoulder position
Poor installation of shaft, bearing pedestal machining accuracy, improve the installation method, improve the installation accuracy
Insufficient lubricant, brand name is not appropriate to supplement the lubricant, choose the appropriate lubricant
To modify the contact part of labyrinth seal by mutual contact between rotating parts
Regular sound due to foreign body rolling surface indentation,
Replace bearings with rust or bruises, clean related parts, and improve seals using clean lubricants
Replace bearing with brinell indentation using correct mounting method
Roll to the surface fatigue peeling replacement bearing
Irregular sound clearance too large correction with bearing clearance, adjust the preload
Foreign body invasion replace bearing, clean related parts, improve sealing device, use clean lubricant
Ball injury, peeling replacement bearing
Abnormal temperature rise lubricant too much to reduce the amount of lubricant, choose a harder grease
Insufficient lubricant, brand name is not appropriate to supplement the lubricant, choose the appropriate lubricant
Abnormal load correction fit and bearing clearance, adjustment of pre-tightening, adjustment of bearing seat shoulder position
Poor installation improves the machining accuracy of shaft and bearing housing, improves the installation method and improves the installation accuracy
Creep of mating surface
Too much friction in the sealing device to replace the bearing, modify the fit, modify the shaft and bearing seat, improve the sealing structure
Large vibration (shaft swing) brinell indentation replacement bearing, using the correct installation method
Peel and replace bearings
Poor installation to correct the shaft, bearing block shoulder perpendicularity, spacing ring end face of the perpendicularity
Foreign body invasion replacement bearings, cleaning parts, improve the sealing device
Lubricants leak badly, discoloration lubricants is excessive, foreign body invades
Wear debris invasion lubricant to the right amount, consider re-selection of lubricant or replacement of bearings, clean the bearing seat
