QIBR - NCF 2240 ECJB/P5 Cylindrical Roller Bearing Optimization
Selectable Precision, Vibration, and Noise Levels: Options include P6, P5 for precision, V2, V3 for vibration, and Z2, Z3 for noise.
Cage Material: The cage material can be chosen based on operating conditions, with options including steel, brass, or nylon.
Grease Replacement: Select lubrication according to bearing working requirements, such as SKF LGMT 2, Timken GR217, or Shell Gadus S2 V220AC.
Optimized Roller Profile: Depending on operating conditions, logarithmic profile curves can be used to optimize the roller profile, reducing stress concentration between rollers and raceways, and enhancing load capacity and service life.
More customization: QIBR can design and optimize bearings according to customer drawings and operating conditions.
QIBR - NCF 2240 ECJB/P5 Cylindrical Roller Bearing Quality Control
Dimension measurement: Various high-precision instruments are used to measure multiple dimensions of the bearing, with an accuracy of up to 0.001mm.
Rotation accuracy: A dial gauge measures minor surface flaws or deviations, with measurement accuracy reaching 0.001mm.
Hardness measurement: Surface hardness is measured using a hardness tester, with an accuracy of ±0.5HRC.
Metallographic analysis: Internal metallographic structure is analyzed using a professional metallographic microscope.
Geometric tolerance: A contour gauge measures the bearing's geometric shape and relative position.
Noise monitoring: A vibration meter monitors vibration during operation to obtain noise data.
Raw material control: Steel and parts are sourced from ISO 14001-certified suppliers, ensuring product stability while promoting sustainable development.
Особенности и преимущества
By enhancing the design with reinforced structure, incorporating logarithmic profile rolling elements, and internal optimization, the bearing is endowed with advantages such as high load capacity, low friction coefficient, minimized resistance, leading to significantly increased bearing lifespan and reduced maintenance costs.
The outer ring is made of high-purity special high-quality bearing steel processed by high-speed forging + cold rolling process, and the raceway surface is carbonitrided.
