C 6910 V CARB Cylindrical Roller Bearings P6 P5 P4 Without Cage 50x72x40mm

1. Product Overview
C6910V is CARB self-aligning full complement cylindrical roller bearing, also known as ring roller bearing. The suffix V represents cage-free full roller structure. Standard metric dimensions: inner bore d=50mm, outer diameter D=72mm, overall width B=45mm.
Adopts unique curved roller and symmetrical arc raceway self-aligning design, which can simultaneously offset shaft bending deformation, assembly parallel deviation and axial thermal expansion. It effectively avoids roller edge stress, abnormal noise and premature seizure caused by installation errors and temperature variation. The full roller layout maximizes internal rolling elements quantity, providing much higher radial load capacity than caged cylindrical roller bearings, perfectly suited for long-term low-speed heavy-load continuous operation.
Inner ring, outer ring and cylindrical rollers are all manufactured with fully quenched GCr15 bearing steel and ultra-precision mirror grinding curved raceway, delivering stable rolling performance and superior wear resistance. Widely matched for printing press main rollers, heavy bulk material conveyor rollers, papermaking calender rollers, textile heavy calendaring equipment, light lifting and construction heavy transmission machinery.

3. Core Advantages

• Exclusive CARB curved roller self-aligning mechanism, three-dimensionally compensates shaft deflection, mounting offset and thermal axial elongation, preventing local edge abrasion and roller jamming.
• Cage-free full complement roller structure, fills maximum number of rollers inside bearing cavity, ultra-high radial rigidity and heavy load bearing capacity, ideal for equipment running under sustained heavy load.
• All rolling parts adopt integral quenching plus mirror superfinishing process, high surface hardness, stable precision retention during long-time low-speed heavy rotation, greatly extending service life.
• Symmetrical arc inner and outer raceway, evenly distributed contact stress on every roller, smooth stable rotation with low noise even under slight assembly misalignment.
• Wide compact integrated bearing design, single bearing replaces combined cylindrical and spherical roller bearing sets, simplifying shaft structure and cutting equipment assembly cost.
• Large internal grease storage cavity, holds sufficient lubricating grease to extend refueling maintenance cycle, adaptable to low-maintenance industrial workshop environments.
• Standard metric universal installation dimensions, fully interchangeable with international standard CARB series bearings, no modification needed for shafts and housings.
• Comprehensive customized services: stainless steel anti-rust material, OEM laser marking on outer ring, neutral export carton anti-rust packaging, special grease filling for extreme temperature conditions.
