C 6915 V CARB Toroidal Roller Bearing Full Complement 75x105x54mm

1. Product Overview

C6915V is CARB self-aligning full complement cylindrical roller bearing, also known as ring roller bearing. Suffix V stands for cage-free full roller construction. Standard metric dimensions: inner bore d=75mm, outer diameter D=100mm, overall width B=60mm.

It adopts exclusive curved roller plus symmetrical arc raceway self-align design, which can simultaneously compensate shaft bending deformation, assembly parallel offset and axial thermal expansion. It effectively eliminates roller edge stress, abnormal noise and premature seizure caused by installation errors and temperature fluctuation. The full roller layout maximizes the number of rolling elements inside the bearing, delivering far stronger radial load capacity than caged cylindrical roller bearings, perfectly suited for continuous low-speed heavy-load working conditions.

Inner ring, outer ring and cylindrical rollers are all made of fully quenched GCr15 bearing steel with ultra-precision mirror grinding curved raceway, featuring stable rolling performance and outstanding wear resistance. Widely applied to 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

• Unique CARB curved roller self-aligning mechanism, three-dimensional compensation for shaft deflection, mounting offset and thermal axial elongation, preventing local edge abrasion and roller jamming.
• Cage-free full complement roller structure, fills maximum quantity of rollers inside bearing cavity, ultra-high radial rigidity and heavy load bearing capacity, ideal for equipment running under long-term sustained heavy load.
• All rolling parts adopt integral quenching and mirror superfinishing process, high surface hardness, stable precision retention during long-time low-speed heavy rotation, greatly extending service life.
• Symmetrical arc inner & outer raceway, evenly distributed contact stress on each roller, smooth stable rotation with low noise even with slight assembly misalignment.
• Wide compact integrated bearing design, single bearing replaces combined cylindrical + spherical roller bearing sets, simplifying shaft structure and reducing equipment assembly cost.
• Large internal grease storage cavity, stores sufficient lubricating grease to extend refueling maintenance cycle, suitable for low-maintenance industrial workshop environments.
• Standard metric universal installation dimensions, fully interchangeable with international standard CARB series bearings, no modification required 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.
