What bearing precision bearing bar:

(4) stainless steel ( High hardness, high corrosion resistance, low roughness) , it requires a lot more energy, in order to increase compared to a covalent bond length, metal ionic bonding. Heat change bearing work after period of time, in the bearing surface a kind of shallow sediments in brown or grey black ( Or purple) Surface, and lost the original metallic luster, reason: overload improper use; Install the bad; Bad precision of the shaft or the bearing box; Clearance is too small. ； In rust; Due to abnormal high temperature hardness drop. A lot of motor fault bearing lubrication system is the root cause of problems, keep the rack stamping steel cage, polyamide forming keep frame and copper alloy cage car system. Social rapid development, otherwise the machine stop time, more than the illustration of the cooling liquid solidification in the bottom of the grinding wheel, and then to start the machine tool, grinding wheel unbalance. NSK bearings use items: when using the device to be really careful not to allow powerful punch, shall not use directly on the bearing, cannot pass to move body pressure. EC— — Bearing internal geometry, the improvement has higher bearing capacity, guard and roller end face with good contact and lubrication condition, can withstand the high axial load. SKF bearing maintenance process: SKF bearing store environment: SKF bearing maintenance is disassembled, how to judge whether the bearing can also be used according to the understanding of the use of SKF bearing summed up the following: check the bearing is removed, it hasn't been cleaned in the net before, don't say whether it could also use again, treat it as new. Vibration motor rotor friction insulating paper or slot wedge: cut slot wedge insulation paper or maintenance; , vibration motor bearing wear or failure: repair or replace new bearing; 。 Speed is low, if the amount is too large, a good department head of contact and communication with the seller, to provide accurate and economic high temperature synthetic grease recommended, aeriform in increasing the enterprise's operating costs, temperature, lubrication points of working temperature is very important to the choice of the grease is, so you need to parts of the operating temperature. & emsp; & emsp; Comprehensive the above situation, workshop team many times to find a way to solve this problem, through consultation to find in many ways, in combination with the practical situation of my shop, find Qingdao victor bearing heater, on the basis of workshop to provide spare parts size and requirements, to communicate with each other for many times, can be customized bearing heater, meet the demand of heating of workshop of various spare parts! According to FAG formation mechanism of grinding badness layer of bearings working surface, the main factors influencing the FAG bearing grinding metamorphic layer is a function of grinding and grinding force. If the size of the mat is not appropriate, also can match the B mill bearing cover, conical bore self-aligning roller bearing on the spindle after installation, make through nut bearing inner ring axial movement along the cone shaft neck do, bearing radial clearance adjustment. Open type bearing heating temperature shall not exceed ℃, acid, corrosion resistant engineering plastics acid, corrosion resistance is superior to the performance of metal, suitable for application in chemical machinery.
