1、 Model meaning
02: Wide cross-section heavy-duty series, wider and capable of carrying larger loads than 01 models with the same inner diameter
E: Reinforced structure, roller lengthening and thickening, optimized raceway, impact resistance, and increased load capacity
B: Split cylindrical roller bearing
225: Bearing nominal inner diameter of 225 millimeters
M: Brass solid holder, resistant to high temperature, impact, heavy load and not easily deformed
2、 Standard size parameters
Inner diameter: 225 mm
Outer diameter: 355 mm
Width: 135 mm
3、 Basic performance
Material: High carbon chromium bearing steel GCr15, with high quenching hardness, wear resistance and fatigue resistance
Structure: The entire structure is 180 ° fully split, with the inner and outer rings, rollers, and cage all half detachable
Applicable working conditions: low-speed heavy load, alternating impact, high dust, humid and harsh industrial and mining environment
Temperature resistance range: -30 ℃ to 180 ℃
Capable of micro centering performance and compatible with minor misalignment of shaft systems during installation
4、 Core structural advantages
The 02 wide series heavy-duty design has a wide and thick cross-section, multiple roller arrangements, and a large load-bearing area. Compared to the 01EB series with the same inner diameter, it has a stronger load-bearing capacity and is suitable for supporting heavy loads in large and medium-sized heavy industries.
The fully disassembled shaft installation does not require disassembling the main shaft, moving the coupling and gears. It can be directly opened and disassembled on the shaft, making maintenance fast, labor-saving, and reducing downtime losses.
Compared to the ordinary 02B225M, the E-type reinforced upgrade enhances the roller and raceway structure, providing impact resistance, wear resistance, and a longer overall service life.
The brass solid holder has sufficient rigidity, high temperature resistance, and compression resistance, and is not easily deformed or cracked during long-term continuous operation. It is suitable for all-weather non-stop working conditions in mining and metallurgy.
Optional sealing protection options include labyrinth seals and skeleton oil seals, which are dust-proof, waterproof, and prevent impurities from entering the bearing interior, making them suitable for harsh environments.
5、 Applicable device scenarios
Mining shearer arm, scraper conveyor, ball mill, large crusher; Metallurgical cement rotary kiln, conveying and transmission equipment, auxiliary shaft system of rolling mill; Port cranes, bucket wheel machines, and large winch walking mechanisms; Heavy load support positions with a shaft diameter of 225 millimeters, difficult disassembly and assembly, and requiring online maintenance in industries such as shipbuilding, papermaking, and grain and oil heavy industry.
6、 Key points for installation and maintenance
Before installation, clean the mating surface between the journal and the bearing seat, align the two halves of the bearing seam, and tighten the splicing bolts diagonally and evenly; Add extreme pressure heavy-duty grease and fill two-thirds of the cavity; Daily regular grease replacement inspections, if there is a high temperature rise, abnormal noise, or excessive vibration, promptly check the bolt pre tightening force and sealing status.
