Installation instructions for several types of bearings

wallpapers Tech 2020-12-11

When installing the bearing, the force should be uniform and not directly hammered. For example, if the interference is large, the bearing should be heated in an automatic temperature-controlled air heating furnace or oil furnace, and the heating temperature should be strictly controlled below 120°.

(1) Installation and use of deep groove ball bearings

When installing the bearing, the force should be uniform and not directly hammered. For example, if the interference is large, the bearing should be heated in an automatic temperature-controlled air heating furnace or oil furnace, and the heating temperature should be strictly controlled below 120°.

 

Bearings equipped with nylon cages can work continuously and stably at -40°-120° for a long time, working at 150° should not exceed 4 hours, and the short-term temperature peak should not exceed 180°.

 

The warehouse where the bearings are stored should be clean, dry and not allowed to be stored in the same warehouse as chemical products, the relative humidity should not exceed 65%, and the bearings are not allowed to be stored on the ground.

 

(2) Installation and use of spherical roller bearings

The user should select the appropriate fit and the radial clearance of the bearing according to the user requirements. Please check the bearing code first after unpacking.

 

Before the bearing is installed, if it is necessary to add grease to the bearing, the grease must be clean and appropriate.

 

It is advisable not to directly hammer the inner and outer ring end faces and rollers during installation to avoid cracking the inner ring or the middle and small ribs. Generally, users should put the bearing in mineral oil and heat it to 90°-100° and install it on the spindle immediately. Do not use the local spray burning method for the bearing, and the user should also use a special sleeve to install when it is difficult to "hot install".

 

The bearing should have a good sealing and dustproof device and lubrication, and the oil should not be cut off.

 

The bearing warehouse should be clean and dry, free of environmental pollution, the bearings should not fall to the ground, and the packaging should not be damaged. Bearings in stock for more than 1 year must be cleaned and oiled again.

 

(3) Installation and use of thrust spherical roller bearings

When installing the bearing, clean the bearing oil seal and apply clean, high-quality lubricant.

 

When installing the bearing, the force should be uniform and not hammered. If the matching interference is large, the bearing should be put into mineral oil and heated to 90°-100°, and then installed immediately.

 

The warehouse where the bearings are stored should be clean, clean, and the relative humidity should not exceed 65%.

 

Inventory bearings should be cleaned and oiled every other year, and the oil seal packaging should be kept in good condition.

 

When using bearings, there should be a good sealing and dustproof device, and the working conditions should be checked frequently.

 

(4) Installation and use of cylindrical roller bearings

The bearing is a separate type, and users can adjust the clearance according to their needs when installing.

 

Before use, the bearings should be cleaned with gasoline or kerosene and kept well lubricated.

 

When the bearing is installed, the bearing should be pressed into the component and beating is strictly prohibited.

 

The bearing storage place should be clean and ventilated to avoid moisture. Bearings that require long-term storage should be regularly rust-proof.
