High Speed Auto Ball Rolling Bearing Self-Aligning Roller Bearing for Decelerator Machine

Product Description

Self Aligning Ball Bearings

Self aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. Self aligning ball bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection or housing deformations. Self aligning ball bearings are suitable for applications where the shaft relative to the housing bore is prone to angular misalignments. Under normal loads, depending on the dimensional series, the maximum permissible angular misalignment is approximately 2° to 4°. These bearings are available in open and sealed versions and inner rings with a cylindrical or tapered bore.

Company Profile

DALIAN HONGSHI MACHINERY AND ELECTRICAL EQUIPMENT CO.,LTD. (formerly Dalian Hengmai Bearing Co., Ltd.) was established in 2007, and HMMH is our own brand.
HMMH mainly produces spherical roller bearings, pillow block ball bearing, deep groove ball bearings and cylindrical roller bearings. Spherical roller bearing products range from 20mm to 1M, with the main production of crusher bearings 22300 series. Low noise deep groove ball bearings, product accuracy can reach ZV2, ZV3, ZV4, mainly produces motor bearings 6200, 6300 series. pillow block ball bearing, mainly producing UCP, UCF, UCFL, UCFC, UCT series, the products are mainly used in agricultural machine and peeling machine. We also use the bainite quenching process to ensure the hardness of the bearing, using good testing equipment, such as roundness meter, profiler, roughness meter, universal measuring instrument, spectrometer, metallographic microscope to control each detail quality monitoring.

To ensure product quality, we have established a strict quality control system and an experienced team of engineers and after-sales service. From forgings to final products  we have a strict quality control system.

Your needs are our production motivation, and your satisfaction is our goal. We are willing to serve our customers with the goal of "Quality First, Service First, Credit First".
