1、 Model Definition
02: Wide cross-section heavy-duty series, wider and capable of carrying larger loads than the 01 series with the same inner diameter
E: Enhanced raceway and roller structure, resistant to impact, wear, and higher rated load
B: Split cylindrical roller bearing
70: nominal inner diameter 70mm
M: Brass solid holder, resistant to high temperature, compression, heavy load and not easily deformed
2、 Standard external dimensions
Inner diameter: 70 mm
Outer diameter: 120mm
Width: 55 mm
3、 Basic performance characteristics
Material: GCr15 high carbon chromium bearing steel, with high quenching hardness, wear resistance, fatigue resistance, and impact resistance
Structure: 180 ° fully split in half, inner ring, outer ring, rollers, and cage can be separated as a whole
Suitable operating conditions: low-speed heavy load, alternating impact, high dust, and humid small and medium-sized heavy industry sites
Temperature resistance range: -30 ℃ to 180 ℃
Equipped with micro adjustment capability, it can compensate for slight misalignment of the shaft system during installation
4、 Core product advantages
02 Wide body strengthened load-bearing capacity
Widening section design, dense roller arrangement, large load-bearing area, with a bearing capacity better than 01EB70M with the same inner diameter, and small shaft diameter can also withstand heavy loads.
Free disassembly shaft online maintenance
Without dismantling the main shaft, coupling, or gears, it can be opened and disassembled directly on the shaft, which has high maintenance efficiency, saves labor, and reduces equipment downtime losses.
E-type reinforced durability
The raceway and rollers undergo precision strengthening treatment to resist impact and wear, with a longer service life than ordinary 02B70M.
Brass solid holder
Rigid enough, heat-resistant, and resistant to compression, suitable for 24-hour continuous heavy-duty operation, not easily deformed and not loose.
Can be equipped with sealing protection
Optional labyrinth seals and skeleton oil seals are available to prevent dust, water, and debris from entering the bearing interior, suitable for harsh working conditions such as mining, metallurgy, and cement.
5、 Applicable device scenarios
Small mining machinery, micro crushers, and small winch transmission mechanisms; Metallurgical conveying rollers, cement light industry transmission auxiliary shafts; Textile, grain and oil, and general small-scale heavy industry equipment; All heavy-duty support positions with a 70mm shaft diameter, compact installation space, inconvenient disassembly and assembly, and requiring online maintenance.
6、 Key points for installation and maintenance
The two halves of the bearing are precisely aligned and sewn together, and the diagonal joint bolts are evenly locked; Add extreme pressure heavy-duty grease and fill two-thirds of the chamber with it; Regularly perform routine grease replacement inspections, pay attention to temperature rise, abnormal noise, and vibration, and promptly check the pre tightening force and sealing status of bolts.
