Introduction To Hydraulic Bearing Pullers

The hydraulic puller moves forward directly with the hydraulic starting rod, so the pushrod itself does not rotate. The hook seat can be directly adjusted forward and backward with the thread. During operation, as long as the handle swings back and forth slightly, the hydraulic starter rod moves forward, the hook correspondingly retreats, and the object is pulled out.

The new hydraulic puller is easy to operate and labour-saving. The three claws and the two claws of the Hydraulic Bearing Puller can be dismantled and transformed according to the needs of fieldwork. It can rotate freely. According to the distance between the puller and the centre point of the piston, the centre point of the pulled work piece can be quickly touched. It can be optionally equipped with a pump.

Principle

It moves forward directly with the hydraulic starting rod, so the pushrod itself does not rotate. The hook seat can be adjusted forward and backward directly with the thread. During operation, as long as the handle swings back and forth slightly, the hydraulic starter rod moves forward, and the hook correspondingly retreats to pull out the object. To sum up, it is convenient and quick to operate. Hydraulic puller is an ideal new tool to replace traditional puller. It is easy to operate, labour-saving to use, and not limited by the site. This puller is compact in structure, flexible in use, light in weight, small in size and easy to carry, suitable for factories and repairs.

Function

1. The new hydraulic puller is easy to operate and labour-saving;
2. The three claws and the two claws of the Hydraulic Bearing Puller can be dismantled and transformed according to the needs of on-site work;
3. Optional pump can be selected;
4. It is flexible in use, light in weight, small in size and easy to carry, making it an ideal tool for factories, ships, and repairs.

Instructions

Hydraulic puller is a new ideal tool to replace traditional puller. It has the characteristics of compact structure, flexible use, convenient carrying and operation, less restrictions on site, etc. It is suitable for various maintenance.

1. Tighten the oil return valve stem clockwise before use;
2. Adjust the hook seat so that the hook can grasp the object being pulled;
3. Tilt the piston starting rod back and forth to move forward steadily, and the hook moves back accordingly to pull out the object being pulled;
4. When using, if the extension of the piston start rod needs to be greater than the effective distance of the hydraulic puller piston start rod, it is necessary to stop when the extension distance is close to the maximum effective distance and release the oil return valve rod to let the piston start rod retracts. After adjusting, repeat steps 1-3 again until the object is pulled out;
5. To release the oil return valve system, just loosen the oil return valve slightly counter clockwise. The piston start rod gradually retracts under the action of the spring;
6. The force required by the object to be pulled out must be estimated before use, and the appropriate puller should be selected. Do not use overload to avoid damage.
7. The working oil of the hydraulic puller is preferably anti-wear hydraulic oil, and the working oil must be clean.

Inspection and Maintenance

Hydraulic pullers need to be checked and maintained every six months:
1. Check the gear meshing and wear of all reducers. The pitting damage on the tooth surface should not exceed 30% of the meshing surface, and the depth should not exceed 10% of the original tooth thickness (fixed chord tooth thickness); the percentage of gear tooth thickness wear to the original tooth thickness should not exceed 15%~25% ; Check the state of the bearing; replace the lubricating oil.
2. Check the condition of the big and small wheels. Lubricate
