331981 Tapered Roller Bearings Features and Advantages
Strong Load Capacity: Tapered roller bearings can withstand significant radial and axial forces, making them particularly suitable for handling combined loads. The axial load capacity depends on the contact angle; the larger the contact angle, the greater the axial load capacity.
High Precision: These bearings are manufactured using grinding processes, ensuring high precision, which is essential for applications requiring exacting standards.
Adjustable Clearance: During installation, the clearance can be adjusted by modifying the relative positions of the inner and outer rings, optimizing performance.
Good Rigidity and Impact Resistance: The compact structure of tapered roller bearings provides excellent rigidity and outstanding impact resistance.
Application: They are widely used in fields such as gearboxes, lifting equipment, rolling mills, automotive, metallurgy, petroleum, mining machinery, mechanical manufacturing, and aerospace.
QIBR - 331981 Tapered Roller Bearings Optimization
Heat Treatment: The manufacturing process is optimized through martensitic quenching (standard) and surface hardening heat treatment.
Cage Type: The type of cage is selected based on customer requirements and operating conditions, including options like stamped cages, glass fiber reinforced PA66 cages, and PEEK cages.
Special Variants: For specific application requirements, options include solid oil bearings, INSOCOAT insulated bearings, and NoWear non-wearing coated bearings.
More customization: QIBR can design and optimize bearings based on customer drawings and operational needs.
QIBR - 331981 Tapered Roller Bearings Quality Control
Dimension measurement: Various high-precision instruments are used to measure multiple dimensions of the bearings, achieving a maximum precision of 0.001mm.
Rotation accuracy: A dial gauge is employed to measure minor surface imperfections or deviations, with a measurement precision of up to 0.001mm.
Hardness measurement: Surface hardness is measured using a hardness tester, with a precision of ±0.5 HRC.
Metallographic analysis: Professional metallographic microscopes are used to analyze the internal metallographic structure of the metal.
Geometric tolerance: A profile meter measures the geometric shape and relative positions of the bearings.
Noise monitoring: Vibration monitoring devices assess the vibration conditions during operation to derive 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
Конические роликоподшипники состоят из чашки и конуса. Чашка состоит из наружного кольца, а конус - из внутреннего кольца, роликов и сепаратора. Такая конструкция подшипника воспринимает комбинированные нагрузки и обеспечивает низкое трение при работе. При установке одного однорядного конического роликового подшипника относительно второго конического роликового подшипника и приложении предварительного натяга можно добиться жесткой работы подшипника.
