The usage method of CC Tiebao self-aligning roller bearings is as follows:
Preparation before installation: Clean the environment: Ensure that the installation environment is dry and clean, and avoid dust, dirt, or moisture contaminating the bearings.
Inspection of components: Conduct a detailed inspection of the mating surfaces of the shaft, housing, and bearings to ensure that there is no damage, burrs, or unprocessed molding sand on the surface.
. Clean all relevant connection surfaces and remove impurities. Bearing inspection: Check whether the bearing model and size match the equipment, and confirm that the bearing is free of defects or damage.Installation method: Heating installation: For bearings with large interference fit, oil bath heating (80 ℃ -100 ℃, up to 120 ℃) or induction heating method can be used to expand the bearing and slide it onto the shaft.
. Heating should be uniform to avoid local overheating.Mechanical pressing: For smaller interference amounts, a sleeve and hydraulic press can be used at room temperature to evenly press the bearing into the shaft or housing hole.
. Do not directly strike the bearing end face to avoid damage.Installation of tapered hole bearings: If the inner hole of the bearing is conical (taper 1:12 or 1:30), it can be installed on the cylindrical shaft using a tightening sleeve or a retraction sleeve.
. Adjust the axial position of the bearing by tightening the nut or hydraulic nut until the specified radial clearance is reached.Using a middle mounting ring: When installing bearings with shafts into the shaft holes of the housing, using a middle mounting ring can prevent the outer ring from tilting or rotating, ensuring that the inner and outer rings are correctly aligned.
.Post installation inspection: Tightening inspection: After installation, use locking nuts, locking washers, or locking clips to tighten the bearings to prevent gaps caused by cooling shrinkage.
. Clearance adjustment: Measure the radial clearance of the bearing to ensure it meets the equipment requirements. The clearance adjustment can be achieved through methods such as locking nuts, adjusting washers, or pre tightening springs.Rotation test: Manually rotate the shaft or bearing box, confirm that there are no abnormalities, and then perform no-load, low-speed power operation, gradually increase the speed and load, monitor noise, vibration, and temperature rise.
. If any abnormalities are found, stop the machine immediately for inspection. Lubrication and maintenance: Lubricating grease selection: Choose lubricating grease that is free of impurities, anti-oxidation, rust proof, and has extreme pressure performance, with a filling amount of 30% -60% of the bearing and bearing housing volume. Regular lubrication: According to the operating conditions of the equipment, regularly replenish or replace lubricating grease to ensure good lubrication of the bearings.Regular inspection: Regularly check the operating status of bearings, including parameters such as noise, vibration, and temperature.
. If any abnormalities are found, stop the machine for maintenance in a timely manner.Precautions for use: Avoid overload: Although self-aligning roller bearings can withstand large radial loads and bidirectional axial loads, it is necessary to avoid overloading operation to avoid shortening the bearing life.
.Preventing pollution: Keep the bearings and their surrounding environment clean, avoid dust, moisture, or corrosive substances from entering, and prevent bearing corrosion or wear.
.Standardized operation: When installing and disassembling bearings, special tools should be used to avoid rough operation that may cause bearing damage.
