A: Only if the bearing is mounted mechanically (i.e. without high pressure oil in the fitting joint between bearing and shaft), the hydraulic nut may be removed immediately afterwards. If the hydraulic method is used, it takes ca. 10 to 30 minutes after relieving the oil pressure until the oil has drained completely from the fitting joint. During this period, the axial preload must continue to ac...

A: With special operating conditions – for example high loads acting onthe bearings, shock-type loads, high inner ring temperatures, differentjournal/shaft materials or thin-walled hollow shafts - a different interference fit may be necessary. In such cases, the INA-FAG field service/FIS mountingservice should be contacted. Click here to view more about our angular contact ball bearing

A: The calculated values apply to normal clearance and larger. Forradial clearance values lower than CN, the radial clearance reduction must bechecked individually depending on the application/operating conditions for, asa rule, there must always be a sufficiently large radial clearance in thebearing. Click here to view more about our products.

A： Generally, we recommend – also for documentation reasons - to check the actual initial radial clearance before mounting and the actual final clearance after mounting to ensure that the bearing has been mounted with the specified bearing clearance or radial clearance reduction and with the specified final clearance and to document these reference values for future bearing inspections and check m...

According to the model of bearing and the rate of tolerance tochoose the right substitutes.2.According to the performance parameters, such as rated dynamicload, rated static load and ultimate speed, to choose appropriate substitutes.3.According to the prefix and suffix of original bearing model toidentify the special performance of the product.4.When the info...

A:The following requirements:1.High precision bearing: the main bearing of machine tool is general high precision, precision levels include precision level (P5), high precision level (P4), ultra-precision level(P2).2.High stiffness bearing: For the low speed tool, main bearing can use high stiffness bearing ;For the high speed tool, main bearing should must use angular contact ball bearing, which ...

A: Bearing surface coated with anti-rust oil,you must clean carefully with clean gasoline or kerosene, and then coated withclean quality or high speed high temperature grease before installation.Cleanliness is very important to bearing life and vibration noise.

A: Because the tapered roller bearings produce axial forces when they bearradial loads, to offset this extra additional load must be borne by a relativeset of bearings, mutually offsetting the influence of axial forces.CLICK THE PIC Click here to view more about our bearings

A: 1. The friction coefficient of the rolling bearing is small, so thefriction resistance and starting friction torque of the rolling bearing aresmall, the power consumption is small, and the mechanical efficiency is high;2. The external dimensions have beenstandardized and interchangeable, and the installation, disassembly and maintenanceare very convenient;3. The compact axial structure reduces ...

A: Bearing surface coated with anti-rust oil,you must clean carefully with clean gasoline or kerosene, and then coated withclean quality or high speed high temperature grease before installation.Cleanliness is very important to bearing life and vibration noise. However, wewould like to remind you that fully enclosed bearings do not need to be cleanedand refilled.

A:yes. If there are iron filings, burrs, dust and other foreign objects in the bearing, the bearing will generate noise and vibration during operation, and even damage the raceway and rolling body. Therefore, before installing the bearing, you must ensure that the mounting surface and mounting environment are clean.Click here to view more products of SUNBEARING.

A: generally, the clearance is smaller after the bearing is used, because the clearance reduction caused by the temperature difference between the inner ring and the outer ring is generally greater thanthe clearance increment generated by the load. For the angular contact ballbearings, it will focus on the size of the pre-tightening, if thepre-tightening has made the bearing clearance negative, in...
