High-Precision Bearing Solutions for CNC rotary tables, Robotics, and Automation

The 230 series spherical roller bearings are classified as ultra-light thin-section bearings, featuring a slim wall structure, large bore diameter and relatively compact outer diameter. This streamlined design minimizes radial installation space occupation, making it the ideal solution for machinery with strict dimensional assembly restrictions. The bearings maintain excellent self-aligning performance and stable heavy radial load capacity, with limited axial load bearing capability for standard

The 231 series spherical roller bearings feature a medium-wide thin-wall structure, inheriting the slim outer ring design of the 230 series while adopting an extended roller layout for upgraded load-carrying performance. This design achieves an optimal balance of compact radial installation dimensions and enhanced bearing capacity, reliably sustaining heavy radial loads and permissible axial loads in comprehensive operating conditions.Fully configurable with CC stamped steel, E optimized interna

The 240 series spherical roller bearings are constructed with thin outer ring walls paired with extra-wide barrel roller assemblies, balancing compact radial installation space and significantly elevated load-carrying capacity. Compared with the 230 thin-section range, the extended roller profile delivers enhanced radial load resistance while retaining slim overall radial dimensions.Built-in self-aligning functionality readily compensates for mounting misalignment and shaft deflection to prevent

The 241 series spherical roller bearings adopt ultra-wide barrel roller layout under fixed standard outer and inner diameters, delivering superior radial load capacity among thin-section spherical roller bearing lines for continuous heavy-duty working scenarios. Optimized internal roller geometry maximizes roller contact area, evenly disperses contact stress and maintains steady rotation under combined radial and bidirectional axial loads.Built with natural self-aligning performance, this bearin

Our large bore spherical roller bearings feature bore diameters from 500 mm and above, covering the 239, 230, 231, 232, and 241 series. Designed for extreme operating conditions, these bearings combine high load-carrying capacity, reliable self-alignment, and long service life in heavy industrial machinery.Available with CA, MB, or CAF machined brass cages, the bearings utilize optimized roller geometry and strengthened internal construction to withstand heavy radial loads, shock loads, and cont

The 202 and 203 series single row spherical roller bearings are engineered for compact light-duty rotary equipment that demands stable load bearing and basic self-aligning capacity. Differentiated from double-row spherical roller bearing ranges, this line adopts a single row of symmetrical barrel rollers matched with a spherical outer ring raceway, which effectively offsets slight shaft deflection and assembly misalignment without sacrificing rotational stability.Supplied with two standard cage

The 233 series spherical roller bearings adopt an extra-wide internal roller arrangement, featuring the broadest roller profile among standard medium-bore spherical roller bearing series. The expanded roller contact surface greatly boosts both dynamic and static load ratings, granting outstanding shock resistance for low and medium rotational speed working conditions.We supply a complete selection of cage types including CC stamped steel, E optimized internal geometry, and solid brass CA & MB ca

The 232 series spherical roller bearings feature a medium-wide thick cross-section design, equipped with larger roller profiles compared to the 231 series for improved overall load capacity and shock resistance. Built with reliable self-aligning performance, the bearings deliver robust radial load support alongside moderate axial load tolerance, making them suitable for working conditions combining steady heavy static loads and periodic impact forces.A full spectrum of cage options including CC

The 213 series double row spherical roller bearings feature a medium-width internal structure with compact overall dimensional specifications. With a moderate cross-section design, this range perfectly balances load-carrying capacity and installation space, positioning it as a universal intermediate specification between lightweight narrow series and heavy extra-wide series. Its reliable self-aligning performance effectively compensates for minor shaft misalignment and deflection, maintaining st

Type A Thin Section BearingType A thin section angular contact ball bearings adopt a constant cross-section design. Within the same cross-section series, their cross-section dimensions stay consistent no matter how large the bore diameter is, which sets them apart from standard angular contact ball bearings whose cross-section grows proportionally with bore size.This unified dimensional design allows mechanical engineers to deploy one identical bearing series across multiple equipment lines. It

Type X Thin Section BearingType X thin section four-point contact ball bearings feature a constant cross-section design, meaning that all bearings within the same series maintain identical cross-sectional dimensions regardless of bore diameter. This standardized structure ensures consistent geometry across the entire product range.Unlike Type A angular contact ball bearings, which typically require paired installation to handle bidirectional axial loads, a single Type X bearing is capable of sup

Type C Thin Section BearingType C thin section radial contact ball bearings feature a constant slim cross-section engineered to cut installation space, minimize equipment total weight and lower rotational friction, while delivering stable high-precision rotation.Thanks to the unique structural advantages of constant-section thin wall bearings, mechanical designers can miniaturize equipment layouts and decrease production expenses, without compromising bearing load capacity, running performance o
