01EB260M is a large-bore, heavy-duty reinforced split cylindrical roller bearing, suitable for medium and low-speed heavy-duty shaft systems with an inner diameter of 260mm. Its core advantages include no-disassembly shaft, high load capacity, and easy maintenance.
1. Basic dimensions (mm)
Inner diameter d=260
Outer diameter D=419.10
Inner ring width C=134
Total bearing width B=177.80
Weight: approximately 52 kg
II. Model Meaning (01EB260M)
01: Series code, single-row cylindrical roller, medium and heavy-duty series
E: Strengthening design (increasing roller size, optimizing internal clearance, and improving radial load capacity by approximately 25%)
B: Split type, with full split of inner and outer rings + rollers + cage
260: Inner diameter 260 mm
M: Metric; Brass solid cage
III. Structure and Core Features
Fully disassembled design: All components are split in half, allowing for installation and replacement without dismantling the shaft or moving the equipment. This design boosts maintenance efficiency by over 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); the radial load capacity is about 25% higher than that of the 01B series with 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℃; the brass cage is impact-resistant, wear-resistant, and has good high-temperature stability.
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 ≈ 1000 kN
Basic static load Cor ≈ 1720 kN
Limit speed: 550 r/min for grease lubrication, 750 r/min for oil lubrication
V. Typical Applications
Metallurgy: Large rolling mill rolls, 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
