Single Row Deep Groove Ball Bearings

Ball bearings are so called because they have balls as rolling elements. The load is transmitted from the outer race to the ball and from the ball to the inner race. Since the ball is a sphere it only contacts the inner ring and outer ring at a very small point, which minimizes friction and helps the bearing to rotate very smoothly. This also means that there is a minimal contact area supporting the radial load therefore if the bearing is overloaded the balls can deform and the bearing will fail. More information & Dimensions

Single Row Cylindrical Roller Bearings

Cylindrical roller bearings have rollers instead of balls as the rolling elements. Because the roller is a cylinder, the contact between roller and raceways is a line instead of a point as in the case of ball bearings. Because of this greater contact area the radial load carried by the bearing is spread over a larger area enabling the bearing to handle much greater radial loads for longer periods than a ball bearing of the same boundary dimensions.

Impact Fitting Tool BFT 36 for cold mounting of rolling bearings

Small bearings with a bore diameter up to 55 mm (or outside diameter up to 100 mm) can be cold mounted onto the shaft or into the housing for normal interference fits.

Before proceeding, the shaft should be examined for imperfections or burrs and these removed. The bearing should be positioned exactly at right angles to the shaft, and the shaft should be lightly lubricated with thin oil.

TowerType Bearing Heater 45-120/260 for hot mounting of rolling bearings

The force needed to mount a bearing increases considerably with the size of bearing. Because of this need for greater force larger bearings (> 50 mm bore diameter) cannot easily be pressed on a shaft or into a housing at room temperature. Therefore the bearing or the housing are usually heated prior to fitment. More information & Dimensions
