1. When installing the 2000 type bearing component with no ribs on the outer ring as the floating support, the movement of the rolling element to the ring should not exceed 0.5~1.5 mm. When the rigid long shaft uses the bearing component as the floating support, It should be installed by pressing (upper half). Make the inner ring and rolling body tightly fit with the journal slightly biased to the right. When working, due to the heat, the shaft is heated to expand and elongate, and the inner ring of the bearing is moved to the left together with the rolling elements. At this time, the inner ring and rolling elements are just in the normal position of the outer ring, or close to the normal position, such as the lower half position. 2 When installing a bearing with no ribs on the inner or outer ring, first check whether the axial movement of the inner or outer ring has been restricted. The complete installation is the bearing on the C620-1 lathe shaft (the outer ring has no rib). When installing this type of bearing, be careful not to forget the accessories such as the retaining ring, gland, and circlip of the assembly shaft or box to limit the movement of the inner ring, outer ring or rolling element of the bearing in the axial direction. Improper installation will cause the inner ring or outer ring of the bearing to move out of position in the axial direction, resulting in a mechanical accident. 3 When installing radial short cylindrical rollers, needle rollers, spiral rollers and other types of bearings without ribs on the inner or outer rings, be sure to check the relative positions of the inner and outer rings of these bearings. Due to the wrong size of the journal position of the bearing installation or the position of the box hole during processing, or the wrong position during installation, the inner ring of the bearing often has a large displacement to the rolling elements. This will make the bearing not work normally and wear out very quickly. Mainly engaged in the development, production and sales of non-standard special bearings with an outer diameter of less than 800mm. Full complement cylindrical roller bearings The company has an independent production plant. Tandem Thrust Bearings are the main products of the company's specialized production, mainly used in parallel twin-screw extruders in the rubber and plastics industry, as well as in screw oil presses in the oil pressing industry, and deep-hole drilling rigs for drilling wells and producing oil. and pipe-laying tractor. The STON brand tandem thrust bearing has a production history of 20 years. It is widely used by hundreds of domestic enterprises and exported to India, South Korea, Thailand, Italy and Germany, as well as Taiwan, Hong Kong and other places. Rubber products (radial tires, high pressure pipes, etc.) steel wire braiding machine bearings (representative product STON-267A deep groove ball bearings with flanges) and high-speed wire mill roll bearings (representative product BVCB358322 combined nut cylindrical roller bearings) have formed batches production scale.
