bearings with simple introduction
Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies.
These products, which are of simple design, robust in operation and easy to maintain, are available in single and double row designs and in open and sealed variants. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields. Due to their low frictional torque, deep groove ball bearings are suitable for high speeds.
Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling.
The cage type bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs. Bearings with the suffix E have a higher capacity roller set and are thus designed for very high load carrying capacity.
The bearings are separable and are therefore easier to fit and dismantle. Both bearing rings can be given a tight fit by this process.
Single row cylindrical roller bearings with cage are available as non-locating, semi-locating and locating bearings.Open bearings are suitable for high to very high speeds.
Deep groove ball bearings with the suffix 2Z have gap seals on both sides and are suitable for high speeds.Bearings with the suffix 2RSR have lip seals on both sides made from nitrile butadiene rubber NBR and are suitable for moderate speeds.
By agreement, we can supply bearings with non-contact BRS seals on both sides (suffix 2BRS). These bearings have favourable frictional behaviour equivalent to that of bearings with Z seals . If the inner ring is stationary and the outer ring rotates, the lubricant loss is less than that in bearings with Z seals .
