1.Product Views & Dimensions
Standard series — front
E = mounting width · F = shaft hole
Square housing — front
R / O SERIES
Hub side — oil-bath type
B = height · G = square hole
Side view — full unit
A / B / C / D
Dimension legend:
A — overall length · B — overall height · C / D — hub diameters ·
E — mounting width · F — shaft hole · G — square hole · H — disc hub bore range
Model numbering system — every unit carries an in-house code:
BA-[Series]-[Size], where Series = R (standard, grease-lubricated) /
Q (compact quick-fit) / O (oil-bath, maintenance-free).
Example: a standard grease unit size 165 = BA-R-165;
an oil-bath unit size 225 = BA-O-225.
Cross references — our hub bearing units are dimensionally interchangeable with the
widely used
BAA0003 / BAA0004 / BAA0005 series
(SKF, FKL, PFI and equivalent agricultural hub bearings), and with most OEM disc-harrow
hub assemblies. Send us your current bearing number or worn unit for cross-reference confirmation.
