Installation and use of deep groove ball bearings

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

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

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

4. Inventory bearings should be cleaned every other year for anti-rust packaging.

Installation and use of angular contact ball bearings

1. 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 air heating furnace or oil furnace with automatic temperature control, and the heating temperature should be strictly controlled below 100°.

2. 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 can reach 180°.

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

Installation and use of spherical roller bearings

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

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

3. 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, the user should put the bearing in mineral oil and heat it to 90°-100° and install it on the spindle immediately. Do not use the partial spray burning method for the bearing, and the user should also use a special sleeve to install it when it is difficult to "hot install".

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

5. 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.
