Single Row Cylindrical Roller Bearing

Design Principles: Adopt single row cylindrical roller parallel arrangement design, with line contact between rollers and raceways to maximize radial contact area and achieve high radial load-bearing capacity; separable inner or outer ring structure allows separate installation/disassembly, reducing assembly difficulty and maintenance costs. Some models are equipped with guide ribs to limit axial displacement of rollers, improve operational stability, and allow bearing small bidirectional axial loads; raceways are precision ground to reduce friction loss and adapt to medium-high speed operation. Performance Features: Core Advantage of High Radial Load: Line contact bearing design, radial load-bearing capacity 2-3 times higher than deep groove ball bearings of the same size, maximum radial bearing capacity up to 3000 KN, adapting to heavy-load scenarios. Separable & Convenient Installation: Inner or outer ring can be separated, enabling bearing installation/replacement without disassembling related components, shortening assembly and maintenance cycles. High Rigidity & Precision: P4-class ultra-precision rotational accuracy, raceways and rollers are precision ground (Ra≤0.05μm), strong deformation resistance, ensuring equipment operation accuracy. Medium-High Speed Adaptability: Optimized cage design reduces the impact of centrifugal force, maximum speed up to 4500 rpm with grease lubrication and 6000 rpm with oil lubrication, meeting medium-high speed operation requirements. Long Service Life & Stability: GCr15 material with surface hardening treatment, optimized roller end face design, fatigue life increased by 30% compared with conventional bearings, adapting to long-term continuous operation. Customization Options: Supports non-standard size (inner diameter, outer diameter, width) customization, separable structure customization, corrosion-resistant material customization, special lubrication solutions for high/low temperature, seal type upgrade, and cage material customization.

Working Principle Roller Arrangement and Load Distribution: Single-row cylindrical rollers are distributed parallel within the raceway, forming a uniform line contact structure that efficiently transfers radial loads to the inner and outer rings. The line contact design significantly increases radial load capacity. A small amount of axial load is transmitted through contact between the rollers and the flanges, which also restrict the axial movement of the rollers, ensuring operational stability. Under medium to high-speed conditions, the cage guides the rollers for smooth movement, reducing friction and collision between rollers and lowering operating temperature. Installation Adaptability: The separable structure allows for separate installation of the inner or outer ring, accommodating the interference fit requirements of the shaft and housing bore. Bearing clearance can be precisely controlled by adjusting the assembly tolerances of the shaft or housing bore, compatible with standard interference fits (shaft h7/housing bore H8), meeting the assembly tolerance requirements of most industrial equipment.
