Inner ring is processed through heat treatment and precision machining, tolerance of dimension and geometric accuracy accords to the national standard. There is guiding chamfering at the two ends of the bearing race of the inner ring, which is convenient for installation. They are used for situation when the axis can not be processed with heat treatment and can not be treated as bearing race. When the needle rollers with inner ring and without ring are used together, normal working windage can be reached.
Inner ring tolerance of lr is more than ir, terminal facet is not grinded, the price is low and they are usually used together with needle roller bearing with pressed outer ring.

SWG Inner Ring And SWG Outer Ring
There are many non standard bearings in deep groove ball bearings, with extended inner ring series is the most commonly used one. Standard 608's dimension is 8*22*7mm,Hongtai's 608-ZZ/B16 with extended inner ring on both side,the dimension is 8*22*16mm,and mainly used for casters,wheels,furniture parts etc. The extended inner ring reduces the cost and makes it more widely used. As the most classic 608 bearing, with extend inner ring is widely used on casters and wheels. We can produce 100,000 pcs per shift per month.
There are many non standard bearings in deep groove ball bearings, with extended inner ring series is the most commonly used one. Standard 6201's dimension is 12x32x10 mm,with extended inner ring on both side,Hongtai's 6201-ZZ/B28 is customized,the dimension is 12x32x28,and mainly used for casters,wheels,furniture parts etc. The extended inner ring reduces the cost,more widely used. High quality bearing steel makes the lifespan longer,multitudinous dimensions of inner rings available.
The dimension of standard R4's is 6.35 15.875 4.987mm,Hongtai have four types dimension to choose,such as R4-2RS/B7.14,R4-2RS/B9.04,R4-2RS/B11.4,R4-2RS/B12.5.All of them are customized and mainly used for Home Appliance,Medical Equipment etc. The extended inner ring reduces the cost,and makes more widely used.High quality bearing steel makes the lifespan longer,multitudinous dimensions of inner rings available.
Inner and outer ring of swg Got-400r metal flat gasket can also be processed into the inner and outer ring of the spiral wound gasket. We will punch the gasket that with the size smaller than 8fª by punching machine, and for the one that with large size by lathe. If for the expensive material as ss304, ss316, etc. As long as the sealing plane is not over wide, we will basically use the special ring rolling machine, process by the wire rod, to largely cut cost. The carbon steel outer ring can be coated with zn, white zn, or paint-drying, and the typing will be according to the standards or the demands. Product structure: The metal interface flat gasket, choose kinds of solid metal, mechanically cut and processed into kinds of metal sealing gaskets by high precision nc lathe, suitable for the sealing parts of pressure container, valve, cylinder head with high temperature, high pressure, and strong corrosion. General characteristic is installation area small and preload pressure high. Got-400r metal flat gasket can also be processed into the inner and outer ring of the spiral wound gasket. Got self design and manufacture the ring processing special equipment, outer ring trench cutter, and inner ring chamfering machine. Comparing with the traditional lathe, it is high efficient, low cost, and need no special fixture. Inventory product: Size: Asme b 16.20 1/2fª ~ 24fª 150lb, 300lb, 600lb, 900lb Other sizes or standards on require. Material: Carbon steel, zinc plating, or without zinc plating Ss304, ss304l, ss316, ss316l The following special material on require: Ss321, ss317l, duplex 31803, Ti, ni, inconel, monel, hastelloy, and zr, etc
CSX series cylindrical cross roller bearing is similar to CRB series. The two separable outer rings are connected by circlips.
