INA slewing rings are known worldwide as premium products in the field of rolling bearing technology. These machine elements have proven themselves many times over; they have high load­carrying 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 INA Slewing Ring Bearing 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 KOYO 6304 Bearing 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 designed as four-point contact bearings and as Crossed roller bearing.
