COK®Single Row Spherical Roller Bearings with only one row of rollers,inner ring raceway is concave arc surface, with ribs on both sides, a set of rollers, cage type can be used window glass fiber reinforced polyamide (nylon) to maintain The frame (suffix TN1) can also use machined brass solid cage (suffix MB). The nylon cage can continue to work within a temperature of 120°. If you need to work below 250°, you should choose a solid brass cage. In order to facilitate relubrication, there is a lubricating groove and three oil holes (code suffix /W33) in the middle of the outer ring of the bearing. In order to avoid the arc surface at the maximum diameter of the roller and the oil hole being orthogonal, the oil hole is properly misaligned. COK®Single Row Spherical Roller Bearings have cylindrical holes and tapered holes (the suffix K is 1:12), the radial clearance is different from double row spherical roller bearings, the same inner hole size The radial clearance is much smaller, but the conical hole clearance is larger than the cylindrical hole clearance. Under the normal load, the angular deviation of the inner ring of this type of bearing can be compensated up to 4 when rotating. COK® Single Row Spherical Roller Bearings are especially suitable for occasions where the radial load is large and the centering error needs to be compensated. Under the radial load with impact, the superiority of its structural strength is outstanding. Single row spherical roller bearings cannot transmit large axial loads and are generally not separable.
