deep groove needle roller bearing without rings 3KK 37*42*31E

These bearings are manufactured according to GOST 24310-80. They have a wide application in various spheres of industry, in particular, in supports with high axial loads. Also bearings of this type are characterised by small dimensions in the axial direction and have a fairly rigid design. Most often, this type of products are in demand in units where the formation of raceways is possible when machine parts come into contact, where the most compact bearing units are required. Thanks to the use of high-quality cages made of polyamide, increased product life and the possibility of operation in conditions of increased rotational speed are achieved.
Most often such bearings are used for installation in various shafts of machinery.
