This type of bearing, with its precise design and the integrity of the grooves, is capable of carrying radial and axial loads from both sides. Single-row deep groove ball bearings are manufactured with two types of metal and rubber seals and are usually lubricated with grease at the factory. For this reason, they do not require washing, heating or warming up during installation. The grease in the seals fills about 25 to 35 per cent of the bearing space, and theseseals are spaced from the inner ring of the bearing so that they function optimally when the rings rotate. The technical specifications of deep groove ball bearings include suffixes determined based on the type of cage, clearance type, groove type, material, and seal. These suffixes include Z,ZZ, RS , 2RS,N
