  • Product Description
  • Self-Aligning Ball Bearing 1221 EK TN9 / 1221K 105x190x36 mm

    Description:

    Self-aligning ball bearings are constructed with the inner ring and ball assembly contained within an outer ring with a spherical raceway. This construction allows the bearing to tolerate a minor angular misalignment resulting from deflection or improper mounting. Self-aligning ball bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing.

    This kind of ball bearings isisparticularly suitable for applications where considerable shaft deflections or misalignment are xpected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, enabling it to run cooler even at high speeds.

     

    Competitive Advantage

    1. Quality level: reach the same level as the Japanese and European bearings

    2. Tolerance level: ABEC-1 (P0), ABEC-3 (P6)

    3. Less coefficient of friction

    4. High limiting speed

    5. Large size range

    6. variations of structure

    Features:

    High-Quality Steel – Ultra clean steel to extend bearing life by up to 80%.

    Advanced Grease Technology – lubricants that can extend grease life and performance.

    High-Grade Balls – Quiet and smooth operation even at high speed.

    Super Finished Raceways – Specially honed to minimize noise and improve lubricant distribution and life.

    Contact Angle – Offered in 15, 25, 30, and 40-degree angles.

    Cages – Available in a range of Polyamide, steel, and brass cage assemblies
