Determination of Casting Material for Sliding Bearing Seat

Gray iron castings are mainly used for castings with thin castable walls and complex shapes. Gray cast iron has good wear resistance, good liquid fluidity, small solidification shrinkage, high compressive strength, good shock absorption, sufficient strength and stiffness when used, and suitable price. The sliding bearing seat mainly bears pressure and can meet the working requirements of the sliding bearing seat. Therefore, gray iron castings are selected. The commonly used HT200 has good performance in gray cast iron and is easy to process and cast. Therefore, HT200 is selected as the casting material.

Do you make bearing seats with many advantages

The outer diameter of the bearing and the inner diameter of the bearing seat with the self-aligning function are spherical and have the self-aligning function, which can compensate for axis misalignment and bottom surface deformation caused by installation errors.

Due to the same internal structure of the outer ball bearing as the 6100.6300 series deep groove ball bearing, the FS outer ball bearing with a seat not only bears radial loads, but also bears certain axial loads. And has low noise bearings.

2. Long service life Outer spherical ball bearings with seats are commonly used in harsh working environments such as dirt, dust, humidity, and high temperatures. The grease inside the bearings can deteriorate in a short period of time. Therefore, it is necessary to relubricate the outer spherical ball bearing with seat at appropriate intervals, replacing the deteriorated grease with fresh grease. FS cast iron outer spherical ball bearings are equipped with grease nipples that can be re lubricated to ensure performance and long service life in any working environment.

3. Normal temperature, low temperature, and high temperature lubricating greases can be selected according to different ambient temperatures. The outer ring of the bearing has an oil groove, which can better ensure that the lubricating grease can be smoothly injected into the bearing from the oil nozzle.

4. The outer spherical ball bearing has excellent sealing performance on both sides and is heat resistant. Oil proof rubber sealing ring and steel plate dust cover are combined for sealing. The dust cover is assembled on the outer diameter of the bearing inner ring and rotates with the inner ring to prevent external foreign matters from entering the inside of the bearing and prevent external pressure from protecting the bearing. The combined seal consisting of a sealing ring and a dust cover can prevent soil, dust, and water from entering the bearing and prevent grease leakage within the bearing. Keep the bearing operating performance in harsh working environments.

5. The sturdy heavy-duty bearing seat is of an integral seat structure, preventing deformation of the bearing during assembly. The bearing is durable under any working condition. The bearing seat can be made of gray cast iron, ductile iron, and cast steel.

6. The bearing can be easily locked onto the shaft

There are four methods for locking bearings onto the shaft. The commonly used method is to lock the two fastening screws such as the extension end of the inner ring, or to lock them with a fastening sleeve, locking sleeve, or eccentric sleeve. All four methods can easily lock the bearing onto the shaft.

7. The bearing inner ring has undergone special heat treatment. The inner ring groove and its surrounding components that require hardening, as well as the extended end of the inner ring that is typically hardened with fastening screws, are locally tempered at high temperatures to maintain toughness and impact resistance. During the operation of the bearing, the inner ring screw hole is tempered at local high temperatures to improve the performance of the bearing and avoid loosening of the screws. Tightening the screws too tightly will not cause the inner ring to burst.
