The bearing comprises a bearing cup, a bearing cone and rollers, wherein the roller are positioned between the bearing cup and the bearing cone, and the shield is sheathed between the bearing cup and the bearing cone and is provided with pressure release grooves. The shield is characterized in that the shield is provided with nine pressure release grooves 511, the pressure release grooves are in alternate arrangement on the shield of the bearing, and the width of the widest edge of the pressure release groove 511 is 0.1 to 0.14cm. The shield has the advantage that the width of the widest edge of the pressure release groove is reduced, and the number of pressure release grooves is increased, so the dust is difficult to enter into the bearing and the operation of the pressure release grooves is not affected.
