Self-aligning roller bearing wear and tear of what are the reasons

Wafangdian bearing - Bearing - comfortable and durable On June 29, the authors explain for you: bearing self-aligning roller bearing manufacturing sales and after-sale technical support has a very rich experience, to introduce a cut heart what are the cause of the roller bearing wear and tear, the friction on the surface of small peak valley squeeze each other, gradually fall off the surface layers of brittleness and wear. 1. Oxidation wear and tear. Bearing tiny peak valley of relative motion appearance and oxidation synthesis and in the air and substrate metal joint fragile brittle oxide, the oxide off in the friction, wear called oxidation wear. 2. Friction heat generating wear when bearing in high speed under the condition of heavy load and poor lubrication, appearance in the peak valley due to friction decreased hardness and wear resistance high temperature, contact, adhesion and tear occur even. The wear and tear, called friction heat and wear. 3. Hard wear. If the bearing when the relative motion. Organization uneven bearing movement appearance, the presence of hard particles, or between the movement appearance of bearing fall into impurities such as grains of sand, chip, chip, bearing in relative motion, hard or impurities can make the bearing surface scratch groove, even the wear and tear, called hard wear. 4. Pitting corrosion and wear. Gears, bearings and rolling contact surface, the relative process periodically by a lot of contact pressure, long effect, metal fatigue phenomenon appearance, makes the bearing tiny crack and erosion on the surface, the wear is called pitting wear. Self-aligning roller bearing wear and tear what are the reasons: due to rust or corrosion, chemical corrosion effect caused by the wear and tear. Bearing appearance of acid, alkali, salt liquid or the erosion of harmful gases. To speed up the wear process, the wear called chemical corrosion effect caused by the wear and tear. The microstructure of the metal or chemical composition change, lower the bearing surface wear resistance, hardness, speed up the wear process. The wear and tear, called high temperature effect caused by the wear and tear. Due to water, acid, alkali, salt, liquid and harmful gas such as temporary contact corrosion damage: the movement of the bearing on equipment. Due to rust or corrosion and damage, known as corrosion damage. Bearing comfortable and durable, )
