Bearing - type
(a)$$\,\,\,\,\,\,$$ Ball bearing
(b)$$\,\,\,\,\,\,$$ Roller bearing
(c)$$\,\,\,\,\,\,$$ Needle bearing
(d)$$\,\,\,\,\,\,$$ Taper roller bearing

Loading condition
(p)$$\,\,\,\,\,\,$$ Tangential load
(q)$$\,\,\,\,\,\,$$ Radial load
(r)$$\,\,\,\,\,\,$$ Heavy radial load with impact
(s)$$\,\,\,\,\,\,$$ Light radial load with space limitation
(t)$$\,\,\,\,\,\,$$ Heavy radial and axial load
(u)$$\,\,\,\,\,\,$$ Fatigue load
