01EB180M is a medium-sized, reinforced split cylindrical roller bearing, suitable for medium and low-speed medium-to-heavy-duty shaft systems with an inner diameter of 180mm. Its core advantages include maintenance-free shaft, easy maintenance, and enhanced load capacity.
1. Basic dimensions (mm)
Inner diameter d=180
Outer diameter D=285.75
Inner ring width C=89
Total bearing width B=109
Weight: approximately 21 kg
II. Model Meaning (01EB180M)
01: Series code, single row cylindrical roller, medium load series
E: Enhanced design (increased roller size, optimized internal clearance, with radial load capacity increased by approximately 25%)
B: Split type, with the inner and outer rings, rollers, and cage all split
180: Inner diameter 180 mm
M: Metric; Brass Solid Cage
III. Structure and Core Features
Fully disassembled design: All components can be split in half, allowing for installation and replacement without dismantling the shaft or moving the equipment. This design enhances maintenance efficiency and is suitable for narrow spaces.
Enhanced medium load: Radial load capacity is superior to the 01B series of the same size; supports both axial positioning at the fixed end (GR) and axial sliding at the floating end (EX).
Material and heat resistance: Bearing steel GCr15, quenched, with a working temperature up to 180℃; brass cage, impact-resistant and wear-resistant.
Alignment tolerance: Allow a **±0.5° static alignment error** to accommodate frame deformation and installation deviations.
IV. Rated load (for reference)
Basic dynamic load Cr ≈ 557 kN
Basic static load: Cor ≈ 920 kN
Limit speed: 750 r/min for grease lubrication, 1000 r/min for oil lubrication
V. Typical Applications
Metallurgy: Rolls for small and medium-sized rolling mills, and roller tables for continuous casting machines
Mine: belt conveyor drum, crusher, coal machine shaft system
Electric power: induced draft fan, forced draft fan, small coal mill
Cement: reducer, small rotary kiln supporting roller
Papermaking / Sugar Manufacturing: Press Roller, Dryer Shaft
General machinery: large reducers, agitators, mixers
