INA slewing rings are known worldwide as premium products in the field of rolling bearing technology. These machine elements have proved themselves many times over, have high load carrying capacity, a versatile range of applications and are highly cost-effective. Due to their design, a single bearing can reliably support radial, axial and tilting moment loads. It is therefore possible in many cases to replace bearing arrangements comprising a combination of radial and axial bearings by a single bearing. This reduces, in some cases considerably, the costs and work required in the design of the adjacent construction and the fitting of bearings.Slewing rings are sealed on both sides, lubricated with a high quality grease, can be relubricated via lubrication nipples and are particularly easy to fit. The bearing rings are supplied without gear teeth or, in order to achieve simple drive solutions, are available with external or internal gear teeth.INA slewing rings are available as four point contact bearings and ascrossed roller bearings.

Cylindrical roller bearings with snap ring grooves are full complement, self-retaining units comprising solid inner and outer rings, rib-guided cylindrical rollers and sealing rings.The outer rings have grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and are held together by a steel strip that is rolled into place. Cylindrical roller bearings with snap ring grooves are locating bearings. These bearings are highly rigid and can support axial forces in both directions as well as high radial forces.Due to the full complement design of these bearings, they have the largest possible number of rolling elements and thus extremely high basic dynamic and static load ratings. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.

Sealing rings are designed as contact seals. They protect the bearing position against contaminants, spray water and excessive loss of grease.The sealing rings are matched to the small radial dimensions of drawn cup needle roller bearings and needle roller bearings. They are very easy to fit, since they are simply pressed into the housing bore.Sealing rings allow circumferential speeds at the seal lip of up to 10 m/s, dependent on the surface quality of the shaft.
