The dent in the bearing outer ring track can cause vibration

In this case, the machine operator or maintenance engineer must insist on Wholesale Mechanical roller bearings the needle roller bearing failure signal alarm.They are mainly used for the front and rear hubs, active bevel gears, and differentials of automobiles. Normally, The selection of specifications, dimensions and accuracy according to the location of use, use conditions and environmental conditions, and a suitable needle roller bearing are the prerequisites to ensure the life and feasibility of the bearing. need to check the running state of the machine, where the bearing is the focus of people's attention, and preparing a thorough inspection plan has become more and more important.5 times the limit speed of the needle roller bearing.

Allowable tilt angle: Tapered roller bearings generally do not allow the shaft to tilt relative to the housing hole. The dent in the bearing outer ring track can cause vibration.2 times the limit speed is the best. Allowable speed: In a properly installed and well-lubricated environment, it is allowed to be 0. Part of use: Tapered roller bearings are suitable for bearing combined radial and axial loads based on radial loads.

Allowable temperature: Under normal load, the lubricant has high temperature resistance, and the lubrication is sufficient, generally needle roller bearings are allowed to work at an ambient temperature of -30℃-150℃. Because it is the most important condition monitoring of all rotating mechanical components to prevent needle bearing damage and prevent unplanned maintenance equipment from causing bearing damage during the shutdown period, it is an important part of the early detection of bearing damage at home.

As for the noise generated by the equipment caused by knocking scars, this kind of noise needle roller bearings have different speed levels. But not all machines are equipped with this advanced equipment. They are usually paired with two sets of bearings. noise. business smooth and crisp sound, sharp squeaking noise may be caused by improper needle bearing clearance caused by insufficient lubrication can also cause metal noise.

Transmission parts such as gearboxes and reducers. If tilted, the maximum is not more than 2'. This kind of sound appears when the surface is damaged on the launch date, if the bearing hissing, the sound pollution often causes severe damage to the bearing and causes huge irregularities. If there is intermittent noise, then the rolling part may be damaged.
