The HGT Thin Section Bearings produce contains seven series of open types and five series of sealed types, with bore diameter ranging from 1 inch to 40 inch and cross section ranging from 0.1875 × 0.1875 inch to 1.000 × 1.000 inch. Three kinds of Open Thin Section Bearings are available: Radial contact (C Type), Angular contact (A Type) and Four-point contact (X Type). Two kinds of Sealed Thin Section Bearings are available: Radial contact (C Type), and Four-point contact (X Type).
Difference between Three Types of Bearings (C, A, and X Type)
The difference is the shape of the groove. For the Thin Section Radial Contact Ball Bearings (C Type), the center of the raceway radius is on the center-line of the steel balls. For the Thin Section Angular Contact Ball Bearings (A Type), the raceway and the steel balls are angularly contacted. The center of the raceway radius deviates from the center-line of the steel balls and symmetrically distributed around the center-line. For the Thin Section Four Point Contact Ball Bearings (X Type), there are two centers of the raceway radius on each side of the raceway and both deviate from the center-line of the steel balls, which enables the Thin Section Four Point Contact Ball Bearings (X Type) to form four-point contact between the raceway and steel balls.
Slim Bearings was used widely in Textile printer, Medical device, Rotary tables, Radar, Communication, Aircraft, Aerospace, Astronomy instrumentation and Industrial robotics etc. because of its characteristic such as small space, light weight and low friction. Sealed four point bearings are pre-lubricated with a general purpose grease.
