Product Description

Thin Section Sealed Four-point Contact Ball Bearings( X type)Thin-section sealed four-point contact ball bearing is also designed for mounting sealing devices on both sides based on a thin-section four-point contact ball bearing. We have many options for the structural form of the sealing device. The speed is lower than a thin-section four-point contact ball bearing.

Type X-Thin section sealed four-point contact ball bearings can carry radial and axial loads in two directions. One thin four-point contact bearing can replace the two angular contact ball bearings. Thin Section Four Point Contact Ball Bearing bore diameter ranges from 1 inch to 40 inches; cross-section ranges from 0.1875 × 0.1875 inches to 1.000 × 1.000 inches.
