When assembling bearings, oil-bath heating can be used, when removing pillow block bearing, you can use a hot oil-pouring leaching methods of heating.
　　Oil-bath heating zone when spherical roller bearings, apply the thermometer to control oil temperature to prevent overheating, and bearings should be placed across the network or at the 50-70 mm from the bottom bracket, do not direct contact with the bottom, to prevent bearing local temperature rise too high and the dirt in the oil-affected.
　　Pillow block bearing anti-wear extreme pressure additives in General can be divided into oily and anti-wear extreme pressure agents two broad categories:
　　Oil additives: pillow block bearing oil additives are formed by metal surface physical adsorption and membrane, to improve the friction of the metal contact surface function, enhanced lubrication. Common oil additives: animal and vegetable oil, higher fatty acids, esters, alcohols and other metal soaps.
　　Anti-mill very pressure agent: with block outside spherical bearing anti-mill very pressure agent most is chemical activity strong of organic compounds, this class compounds in at room temperature Shi not up lubrication role, and in high temperature high pressure Xia can in metal surface born comparison tight of chemical film, this film General are than original metal of melting point low, cut strength small, dang metal surface friction, wear and prevent scrapes of role.
