Tapered Rolling Bearing

Design Principles: Tapered rollers and raceways adopt matched taper angle design, with contact line extensions intersecting at the bearing axis, enabling coordinated transmission of radial and axial loads for efficient combined load bearing; single-row models require paired (face-to-face/back-to-back) installation to form bidirectional axial positioning; double-row models integrate ±2°-3° self-aligning capability through symmetrical roller layout to compensate for installation misalignment and shaft deflection. Precision-ground raceways + optimized roller end face design reduce friction loss and improve operational stability; reinforced material and structural design enhance shock resistance, adapting to high-frequency impact working conditions. Performance Features: Core Combined Load Bearing: Matched taper angle design, capable of simultaneously bearing radial and bidirectional axial loads; double-row models have a maximum radial load of up to 8000 KN, and single-row models have an axial load of 50%-80% of the radial load. Double-Row Self-Aligning Adaptability: Double-row models compensate for ±2°-3° installation deviations, reducing assembly accuracy requirements and improving stability under heavy-load eccentric conditions. High-Precision Positioning: P4-class ultra-precision rotational accuracy, axial runout ≤0.005 mm, meeting micron-level positioning requirements of precision equipment. Long Service Life & Stability: Surface hardening treatment of GCr15 material, precision polishing of roller end faces (Ra≤0.08μm), fatigue life increased by 40% compared with conventional bearings, adapting to long-term continuous operation. Customization Options: Supports non-standard size (inner diameter/outer diameter/width) customization, contact angle adjustment (15°/25°/30°), corrosion-resistant material (SUS440C) customization, special lubrication solutions for high/low temperature, and cage material customization.

Working Principle Roller Arrangement and Load Distribution: The tapered rollers match the raceway cone angle, and the extension lines of the contact lines intersect at the bearing axis, forming a stable load transfer path. Radial load is transmitted through line contact between the rollers and raceways, and axial load is transmitted to the inner and outer rings through the decomposition of forces on the conical surfaces; the symmetrical roller arrangement in double-row models evenly distributes the load, and the self-aligning function is achieved through slight sliding of the rollers along the spherical raceway, compensating for installation eccentricity; the cage guides the rollers for orderly movement, reducing friction and interference, and improving load-carrying efficiency. - Thermal Management: Precision grinding of raceways and rollers + low-friction cage design reduces friction loss and effectively controls working temperature rise (typical temperature rise ≤ 18°C); combined with the thermal stability of heavy-duty special grease or circulating oil, it ensures the thermal stability of the equipment under heavy load and medium-high speed conditions. Installation Adaptability: The inner and outer rings use interference fit with the shaft and housing (shaft h7/housing bore H8), compatible with the assembly tolerance requirements of most industrial equipment; single-row models are installed in pairs (face-to-face/back-to-back) to achieve bidirectional axial load capacity, while double-row models can be installed directly; the self-aligning function reduces the requirements for the parallelism of the mounting base surfaces, simplifying the assembly process.
