Low temperature bearing: zero type bearing types are what's the difference

Return through heavy machinery and transport equipment manufacturer for repair, dust cover or seal on both sides of bearing adopts lifelong lubrication method, need not be maintained. Bearing clearance change failure at work, because of the influence of the external or internal factors, change the original fit clearance, lower accuracy, and the change of 'killed' called clearance failure. With two or more of the bearing axis coupling, produce incorrect line deviation or skew Angle, the diameter of the shaft is too big, too much, causing the inner ring in reducing the bearing clearance. Vibrating motor rewind the number of turns per phase are not equal: wound again, the correct number of turns; Wash bearing, bearing the lack of grease:, add the appropriate grease, make its full of net volume of bearing / ~ /; 。 Even that would only get in a certain area of balance, axis is in the middle of the bearing or gear wheel in the middle or in the middle of the cylindrical objects, but there are also a few is square. It is important to note that the 'cook' oil bearing, bearing should be flat on barrel, and between bearings and the cylinder bottom cushion height about mm piece of wood or steel bracket, heating with infrared thermometer or temperature control the oil temperature. From the manufacturing of forging ratio increase, improve the fiber direction of flow, improve the finishing process, cage deformation under the action of external force, the shape of the cage there are big differences compared with the original shape, called cage deformation. Other features tolerance grade/herculean task - — Equivalent to ISO tolerance grade X for metric tapered roller bearing/CL - — Equivalent to ISO level of tolerance for the imperial tapered roller bearings. & emsp; & emsp; Some bearing in use process not need lubrication for processing, this is called a bearing lubrication system, and there are a lot of bearing lubrication is required during use of maintenance, and the adequacy of lubrication is also very important, if you for bearing lubrication, but do not reach the designated position, is the so-called invalid lubrication, this will bring a lot of disadvantages to bearing. Recommended use: d inner circle hole and shaft with press H/H; Circle the pin hole on the do cooperate with drive by H/r; With the outer shell and D by H/H. Drive with the output shaft hole with the use of clearance fit, the interval for. The cause of bearing run laps fit tolerance: bearing and shaft ( Or bearing chamber) The fit tolerance have strict requirements, different specifications, precision, force, operating conditions such as different to fit tolerance requirement. For most occasions, shaft rotation and radial load direction invariable, the bearing inner ring relative to the loading direction, should choose the transition or interference fit.
