N1016KTNHA/HC5SP Bore 80 Mm, Hybrid (ceramic Rollers) Cylindrical Roller Bearing, Single Row, Super-precision
The N1016KTNHA/HC5SP Hybrid ceramic ultra-precision cylindrical roller bearings are widely used in high-speed, high-precision applications with the risk of shaft current, such as: high-speed electric spindles, machine tool spindles (machining centers, grinding machines), variable frequency motors, turbochargers, semiconductor equipment, and precision rotating mechanisms in aerospace.
The N1016KTNHA/HC5SP bearing is a Hybrid (ceramic rollers) Cylindrical roller bearing, single row, super-precision with an inner diameter of 80 mm , an outer diameter of 125 mm, a width of 22 mm. It typically uses SP (ABEC 7) grade precision tolerances and GCr15SiMn rings, HC5 = Silicon nitride Si3N4 rolling mlement. Its dynamic radial rated load is approximately 65695 N, its static radial rated load is approximately 89124 N. It uses C1 standard radial clearance, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
N1016KTNHA/HC5SP bearings ( 80 mm x 125 mm x 22 mm) have the advantages of Ceramic rolling elements achieve high rotational speed, low heat generation, insulation, and protection against electrolytic corrosion, while also possessing ultra-precision-grade high rigidity and high rotational accuracy, and are therefore widely used in the High-speed electric spindles for machine tools, high-speed motors, precision rolling mills, traction motors for rail transit, and aerospace equipment.

The N1016KTNHA/HC5SP Hybrid ceramic ultra-precision cylindrical roller bearings are primarily composed of high-precision bearing steel inner and outer rings, silicon nitride ceramic cylindrical rollers, and a high-performance cage (solid brass or outer ring guided type). The rollers and raceways are logarithmically modified, allowing for separability of the inner and outer rings, achieving precision grades from P4 to P2.
The ceramic rollers in hybrid ceramic ultra-precision cylindrical roller bearings have low density and high elastic modulus, significantly reducing centrifugal force and increasing limiting speed by over 30%. The electrical insulation properties of the ceramic material effectively prevent electrolytic corrosion, making them suitable for applications with shaft current, such as variable frequency motors. They also feature a low coefficient of thermal expansion, low temperature rise, good thermal stability, and a low coefficient of friction, extending bearing life.
