1、 Model analysis
02: Wide section heavy-duty series, wider and stronger than 01 series E: Reinforced structure, enlarged rollers, optimized raceway, impact resistance, and improved service life B: Cylindrical roller split bearing 250: Bearing inner diameter 250mmM: Brass solid cage, high temperature resistance, impact resistance, and no deformation under heavy load
2、 Core standard dimensions
Inner diameter: 250mm
Outer diameter: 390mm
Width: 145mm
3、 Performance parameters
Material: High carbon chromium bearing steel GCr15, quenched high hardness, wear-resistant and fatigue resistant
Structure: Fully split design, inner and outer rings, rollers, and retainers can all be split in half
Applicable working conditions: low-speed heavy load, alternating impact, high dust, humid and harsh working conditions
Temperature resistance range: -30 ℃ to 180 ℃
Features: Has slight centering ability, compatible with minor misalignment of shaft system installation
4、 Product advantages
02 Wide Series Large Load Capacity
The same inner diameter is wider than 01EB250M, with a large number of rollers and a large load-bearing section, making it suitable for heavy loads on large equipment.
Full section detachable shaft replacement
Without dismantling the main shaft, moving the coupling and gears, it can be directly disassembled and assembled on the shaft, saving time and significantly reducing downtime for maintenance.
E-type Enhanced Upgrade Version
Compared to ordinary 02B250M, the raceway and roller structure are reinforced, impact resistant, wear-resistant, and have a longer service life.
Brass solid holder
High rigidity, high temperature resistance, compression resistance, and long-term continuous heavy load operation are not easily deformed or broken.
Compatible with sealing options
Can be equipped with labyrinth seals and skeleton oil seals to prevent dust, water, and impurities from entering, suitable for harsh mining and heavy industry sites.
5、 Applicable device scenarios
Mining: large coal mining machines, ball mills, crushers, scraper conveyors Metallurgical cement: rotary kilns, large transmission and conveying equipment, rolling mill shaft systems Port heavy industry: cranes, bucket wheel machines, large winch walking mechanisms Ship, papermaking, grain and oil large-scale heavy industry equipment, 250 shaft diameter, difficult disassembly and assembly, and heavy-duty support points that require online maintenance
6、 Installation and maintenance
Install and clean the journal and bearing seat, align the two halves of the joint, and tighten the splicing bolts diagonally and evenly; Add extreme pressure heavy-duty grease and fill two-thirds of the cavity; Regularly perform routine grease replacement inspections, and promptly check the pre tightening force and sealing status of bolts in case of temperature rise, abnormal noise, and vibration.
