    Chrome steel Engine Mechanical Self-Aligning Ball Bearing 1221 EK TN9 / 1221K

    Description:

    Self-aligning ball bearings are constructed with the inner ring and ball assembly contained within an outer ring that has a spherical raceway. This construction allows the bearing to tolerate a small 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 are particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables 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 minimise 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
