22210EK/C3 Spherical Roller Bearing 50x90x23mm Self-aligning Double-row Bearings

제품개요：

In heavy industrial applications, equipment is subjected to punishing loads, shaft deflection, and thermal expansion that would quickly destroy standard bearings. The 22210EK/C3 spherical roller bearing is purpose-built to thrive in these extreme environments. With precise dimensions of 50 mm 보어, 90 mm 외경, 그리고 23 mm 너비, this double-row bearing delivers exceptional load-carrying capacity while accommodating significant shaft misalignment—all without compromising performance or service life.

핵심 성능 이점:

• Exceptional Load-Carrying Capacity
  With a dynamic load rating of up to 107 kN 및 정적 정격 하중 108 kN, the 22210EK/C3 delivers outstanding load capacity for its compact 50×90×23 mm envelope. The double-row design and E-type optimized internal geometry ensure maximum load distribution across all rolling elements.

• 우수한 정렬 불량 조정
  The self-aligning design tolerates angular misalignment between the shaft and housing without increasing friction or reducing bearing life. This is critical in applications where shaft deflection, housing deformation, or installation inaccuracies are unavoidable, such as long conveyor shafts, gearbox output shafts, 그리고 중장비.

• Easy Mounting with Tapered Bore
  그만큼 1:12 tapered bore allows straightforward mounting on cylindrical shafts using standard adapter sleeves. This simplifies installation, 가동 중지 시간 감소, and enables precise clearance adjustment during mounting. The tapered bore also facilitates removal using withdrawal sleeves, simplifying maintenance and replacement.

• 고속 성능
  With a limiting speed of 9,500 RPM and a reference speed of 7,000 RPM, the 22210EK/C3 is suitable for a wide range of rotational speeds. The C3 clearance ensures smooth operation at higher speeds by accommodating thermal expansion and preventing excessive preload.

• Relubrication-Friendly Design
  The annular groove and three lubrication holes in the outer ring facilitate efficient relubrication, ensuring consistent lubrication delivery to the rolling elements and extending service life.
