A thrust ball bearing cannot constrain the radial movement of the shaft or the casing; however, it can constrain the axial movement of the shaft and the casing in one direction; thus; such bearings are generally used in conjunction with deep groove ball bearings; the axes of the shaft and the casing bore are It is necessary to adhere to the concentricity; otherwise the bearing will be prematurely damaged due to stress gathering. In order to eliminate this undesirable phenomenon, a radial gap of 0. 5 to 1 mm may be left between the outer diameter of the race and the hole of the casing. The shaft center line and the outer casing support The surface should ensure that the shaft does not allow the shaft to be skewed and flexed; otherwise, the bearing will be prematurely damaged due to uneven load spread. To eliminate the skew of the bearing axis; the elastic support can be placed on the bearing surface of the race; such as oil resistant rubber, Leather, etc.; or use a thrust ball bearing with a spherical seat.
The thrust ball bearing is a separate bearing; it is divided into a one-way thrust ball and a two-way thrust ball bearing according to its layout. The one-way thrust ball bearing can accept the axial load in one direction; the two-way thrust ball bearing can accept the axial direction in two directions. Loads. They are not able to accept radial loads. Thrust ball bearings also have a seat cushion layout; because the seat surface of the seat cushion is spherical, the bearing has a self-aligning function; it can reduce the influence of the device error. The thrust ball bearing varieties are: metric Thrust ball bearings, inch thrust ball bearings, stainless steel thrust ball bearings, double seals, thrust ball bearings, plane thrust ball bearings, one-way thrust ball bearings, two-way thrust ball bearings, radial thrust ball bearings, single row radial ball bearings Double row thrust ball bearings, three rows of thrust ball bearings, four rows of thrust ball bearings, etc.

Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury. Toughened glass is a kind of safety glass.
Toughened glass can be made on customer's request, clear toughened glass, ultra clear toughened glass, colored tinted toughened glass, printed toughened glass, back painted toughened glass, frosted toughened glass, toughened Laminated Glass, toughened Insulated Glass, toughened Vacuum Insulated Glass and so on.
Toughened glass can be used for furniture, buildings, doors, windows, walls, table tops, fence, partitions, railings, balcony, balustrade, shower room and so on.
