In terms of performance, the advantages of single-row full complement cylindrical roller bearings are concentrated in "heavy load bearing" and "structural reliability". First, **Extremely strong radial load-bearing capacity**: The full complement roller design makes the radial dynamic load rating 40%-60% higher than that of single-row cylindrical roller bearings with cages, and 2-3 times higher than deep groove ball bearings of the same size. It can withstand radial loads of hundreds of kilonewtons and can easily cope with heavy-load impacts of crushers and rolling mills; Secondly, **Excellent impact resistance**: More rollers share the impact load, reducing the stress on a single roller. Third, **Compact structure**: The cage-less design reduces the radial size occupation of the bearing, allowing for more flexible adaptation in heavy-duty equipment with limited installation space; Fourth, **Low maintenance cost**: Simple structure, no vulnerable cage, the failure rate is lower than t…
