1、 Model Definition
02: Wide cross-section heavy-duty series, wider and stronger load-bearing capacity than 01 series under the same inner diameter
E: Enhanced raceway roller structure, resistant to impact and wear, with higher rated load
B: Split cylindrical roller bearing
205: nominal inner diameter 205mm
M: Brass solid holder, resistant to high temperature and compression, not easily deformed under heavy load
2、 Standard size parameters
Inner diameter: 205 mm
Outer diameter: 355 mm
Width: 140 mm
3、 Basic product features
Material: GCr15 high carbon chromium bearing steel, with high quenching hardness, wear resistance, fatigue resistance, and resistance to alternating impact
Structure: 180 ° fully split in half, inner and outer rings, rollers, and retainers can all be completely disassembled
Applicable speed: Designed specifically for low-speed heavy load conditions, not suitable for high-speed operation
Temperature resistance range: -30 ℃ to 180 ℃
Self centering performance: Comes with trace centering, can compensate for slight misalignment of the shaft system installation
Weight: Approximately 58 kg
4、 Core advantages
02 Wide body ultra large load-bearing capacity
Widening and thickening the cross-section, with a large number of rollers and a large load-bearing area, the same inner diameter bearing capacity far exceeds 01EB205M, making it the preferred choice for heavy-duty support of large heavy equipment.
Split and non removable shaft design
No need to disassemble the main shaft, coupling, or gearbox. Simply open and disassemble on the shaft, increasing maintenance efficiency by over 80% and significantly reducing downtime losses.
E-type reinforced durability upgrade
The raceway and rollers are reinforced with precision machining, resistant to impact and wear, and have a service life that is extended by more than 30% compared to the regular 02B205M base model.
Brass solid holder
Strong rigidity, high temperature resistance, and compression resistance, supporting 24-hour continuous non-stop heavy-duty operation of equipment, not easily deformed, and not prone to cracking.
Sealed protection is optional
Can be equipped with labyrinth seals and skeleton oil seals to prevent dust, water, and mineral powder impurities from entering, suitable for harsh working conditions such as mining, metallurgy, and cement.
5、 Applicable device scenarios
Large mines: ball mills, crushers, scraper conveyors, large winches
Metallurgical industry: sintering machine, rolling mill, conveyor roller, auxiliary shaft of continuous casting machine
Cement building materials: rotary kiln, coal mill, large bucket elevator
Paper/Grain and Oil: Large press rollers, drying cylinders, heavy-duty transmission rollers
Other: Heavy load support points with a shaft diameter of 205mm, limited space, difficult disassembly and assembly, and requiring online maintenance
6、 Key points for installation and maintenance
Clean the mating surface between the journal and the bearing seat, accurately align the two halves of the bearing with the joint seam, and evenly lock the splicing bolts diagonally
Add extreme pressure heavy-duty grease and fill the chamber to two-thirds to avoid excessive heating
Daily inspection: Regularly replenish grease, monitor temperature rise, abnormal noise, and vibration, and check bolt pre tightening force and sealing status every quarter
