1. Basic dimensions (mm)
Inner diameter d=250
Outer diameter D=396.85
Inner ring width C=128
Total bearing width B=171.45
Weight: approximately 48.5 kg
II. Model Meaning (01EB250M)
01: Series code, single row cylindrical roller, medium and heavy 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 being split
250: Inner diameter 250 mm
M: Metric; Brass Solid Cage
III. Structure and Core Features
Fully split design: All components are split in half, allowing for installation and replacement without dismantling the shaft or moving the equipment. This increases maintenance efficiency by 80%+ and is suitable for narrow spaces and large shaft systems that are difficult to dismantle.
Heavy-load reinforcement: radial heavy-load + bidirectional axial positioning (GR fixed end) / axial floating (EX floating end); radial load capacity is about 25% higher than that of the 01B series of the same size, suitable for heavy-load impact conditions.
Material and Heat Resistance: The bearing steel GCr15 is quenched, with a working temperature up to 180°C; the brass cage is impact-resistant, wear-resistant, and has good high-temperature stability.
Centering tolerance: Allow **±0.5° static centering error**, accommodating frame deformation and installation deviation.
IV. Rated load (reference)
Basic dynamic load Cr ≈ 920 kN
Basic static load Cor ≈ 1580 kN
Limit speed: 600 r/min for grease lubrication, 800 r/min for oil lubrication
V. Typical Applications
Metallurgy: Large rolling mill rollers, continuous casting machine roller tables
Mine: shearer main shaft, large belt conveyor drum, crusher
Electric power: large induced draft fan, coal mill, feed pump
Cement: rotary kiln supporting roller, high-speed shaft of large reducer
Papermaking / Sugar Manufacturing: Large Press Rolls, Dryer Shafts
Ship: deck machinery, propulsion system intermediate shaft
