Read the manual and the actual purchase of the bearing seat, how the hole from the size of the difference between ah? Do you have any professionals? Please know, tell the above 3 specifications of the four hole spacing, the middle of the shaft hole size, thank you heroes!

China KFC (Kaifeng bearing factory)Data UCF203:Hole spacing: 54.00mm. Diameter: 17mm axis.UCF202:Sample manual data is not available.UCF204: the distance between holes is 63.5mm. With shaft 20mm in diameter.In KF, UC201UC202UC203 spherical bearings, in addition to the bore diameter of different, other dimensions (including outer diameter, width) are the same, you can imagine, although there is no UCF202 and UCF201 data, that they use are bearing UCF203 bearing seat (such as P!).Japan FYH data.UCF202: the distance between holes is 64mm. With shaft 15mm in diameter.UCF203: the distance between holes is 64mm. With shaft 17mm in diameter.UCF204: the distance between holes is 64mm. With shaft 20mm in diameter.In FYH, the UC202UC203UC204 spherical bearings are F204 bearing housings.UK RHP data:SF12 (UCF201) hole spacing 54mm, with the axis of 12mm.SF15 (UCF202), SF17 (UCF203), SF20 (UCF204) hole spacing 63.5mm. The axes of 15mm, 17mm and 20mm are allocated respectively.Data from NTN in Japan is in line with FYH data.SKF ball bearings and KF ball bearings data consistent, bearing seat data (F block), the smallest is the inner diameter of 20mm.Visible, spherical bearings, inner diameter of 12mm to 20mm. The reference data must be consistent with the manufacturer's data. And the best one, don't try to change the brand!
No one answered? All I know is that...17 hole 54*54 in UCF20325 hole 70*70 in UCF205UCF202 15UCF204 20
