The functions required for the ferrule and roll data:
Rolling Fatigue Strength, High Hardness, High Wear Resistance, High Wear Resistance, Strong Functionality, Good Stability, and High Mechanical Strength. Also requires good processability. It is not used according to its use. It also needs impact resistance, heat resistance and resistance. Corrosive.
Information on ferrules and rollovers:
Ferrules and tumbling bodies are usually made of high-carbon chrome bearing steel. Most of the bearings; the use of SUJ2.SUJ2 chemical components in the JJ steel. The large-sized bearings use the chemical composition of the SUJ3.SUJ2 in the world; as a bearing material has been standardized. For example: It is the same kind of steel as AISL52100 (USA), DIN100Cr6 (West Germany), BS535A99 (UK), etc. Further demand for impact resistance; use of chrome steel, chrome molybdenum steel, nickel chrome molybdenum steel, and carburizing Quenching; making the steel have a hardened layer from the outside to the proper depth. The carburizing bearing with proper hardening depth, fine arrangement, suitable hardness and core hardness; excellent impact resistance compared to bearing steel bearing The chemical composition of steel used in ordinary carburizing bearings.
NSK implemented vacuum degassing treatment; therefore; the data used were high in cleanliness, low in oxygen content, and good in quality. The appropriate heat treatment was selected; the life of the rolling tumbling of the bearing was significantly improved.
In addition to the above steel grades; based on special use; also use high-speed steel with excellent heat resistance; stainless steel with good corrosion resistance.
Persistence information:
Stamping the data of the frame; using low-carbon steel. It is not the same as the use; it also uses brass plate, stainless steel plate. Cut the data of the frame; use high-strength brass, carbon steel; also use synthetic resin. Cylindrical roller bearing cylindrical roller and track are line touch; radial load can be large; that is suitable for receiving heavy load and impact load; also suitable for high-speed rotation N-type and NU-type can be moved axially; can be used to thermal expansion or The change of the relative orientation of the shaft and the casing caused by the equipment error; the most suitable for the free end bearing NJ type and NF type can accept a certain degree of unidirectional axial load; NH type and NUP type can accept a certain degree of bidirectional axial load The ring or outer ring can be separated; it is easy to assemble and disassemble NNU type and NN type with strong rigidity against radial load; most of them are used for the first applicable frame of machine tool spindle:
Steel plate stamping holder (Z-shaped), copper alloy cutting frame, pin-type frame, synthetic resin forming frame for primary use:
Medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration equipment, loading and unloading transfer machinery, all kinds of industrial machinery, solid needle bearings, the inner layout of the inner ring bearing is the same as the NU type cylindrical roller bearing; The needle roller is used; the volume can be reduced. 15.

The main use of steel stamping adhere to the frame:
Automotive engines, transmissions, pumps, excavator track wheels, hoists, bridge cranes, compressors

Flap Wheels
Flap wheel, in general will devide in to 2 types: flap wheel with shaft and Chuck Flap Wheel .
Aluminium Oxide Chuck Flap Wheels are an ideal choice for a wide variety of blending, deburring and finishing applications common in the metal fabrication, welding and polishing industries.flap wheels are conformable to intricate shapes and contours. designed to deliver a consistent finish with a uniform rate of cut, flap wheels wear away, continually exposing fresh abrasives.
Flap Wheel With Shaft
Mounted Flap Wheel are a general-purpose tool effectively used in a vide variety of applications ranging from weld removal and deburring to final finishing. They are specially to provide the versatility required in a modern metal-working factory. Providing an optimal finish on both stainless steel and non-ferrous metals.
We distributes and wholesales various brands of Bonded Abrasives , Abrasive Sanding Disc, Cutting Wheels , Flap Disc Backing Pad, Flap Disc Adhesive, and Surface Conditioning Product etc, and enjoy a high position among consumers.
