The self-aligning ball bearing is a double-row ball bearing that is processed into a spherical shape on the outer ring and has two raceways on the inner ring; therefore, it has a self-aligning function. It is mainly used to receive radial load; it can also receive radial load together; Accepts a small amount of axial load; but usually does not accept pure axial load; its speed is lower than that of deep groove ball bearings. This type of bearing is mostly used on double support shafts that are prone to twists and turns under load; and double bearing holes are not guaranteed. The components with strict coaxiality are; however, the relative inclination of the center line of the inner ring and the center line of the outer ring must not exceed 3 degrees.
Self-aligning ball bearing; according to its layout, it is divided into cylindrical inner hole and conical inner hole (taper 1:12); bearing with conical inner hole can be directly fixed on the tapered shaft diameter by means of lock nut; It can be fixed on the cylindrical shaft by using the adapter sleeve.

Soluble Salt

Soluble salt is one series of Polished Porcelain Tiles. Also called vitrified tile. With glazing, polishing and High temperature firing,it makes the tile have perfect abrasion resistance and lower water absorption. That's the reason why it's used in many commercial place like airport,supermarket,mall,office buliding,hotel etc

Polished porcelain tiles


  1. 10mm thiickness for 60*60cm soluble sat tiles and also are water and corrosion resistant.
  2. Super NANO soluble salt tiles is stain resistant and easy to clean.
  3. Packed in seaworthy wooden pallat for exports
