The four-point contact ball bearings are radial single row angular contact ball bearings featuring raceways that can handle axial loads acting in both directions. A limited radial load can be supported for a given axial load.
Slewing Ring turntables have been developed for installation in vehicle trailers. Their purpose is to transmit both the axial load,thrust and traction forces.The standard series turntables shown here are the result of manyyears' design and manufacturing experience in the field of trailersteering systems.Slewing Ring turntables are produced to exacting standards and are designed to meet high performance requirements.Each turntable consists of two steel rings designed for flange mounting. The raceways are machined so as to ensure that the power transmission is favourably directed between the profiled rings and the inserted antifriction bearing steel balls. The turn -tables are delivered with preservation and grease filling.
The turntables are supplied as standard type being filled with lithium-saponified grease of penetration grade 2 and as low-maintenance type being filled with Gleitmo 585K.The turntables are supplied with a surface preservative. This preser-vation is only a temporary protection against corrosion which canprincipally be overpainted with all commercial finishing paints (suchas acrylic resins, one-component and two-component acrylic var-nishes, two-component PU varnishes, two-component epoxy var-nishes) and with bituminous paint. (Attention: Do not paint the seals.)
Our product range comprises ball-bearing and roller-bearing slewing rings, turntables and seamless rolled rings.
As supplied slewing rings are generally packed for storage in a covered store and for a period not exceeding 6 months. Light surface corrosion can usually be removed from exterior surfaces – and it is more important that the raceways are well greased and rust free. Standard commercial solvents can be used to degrease the slewing ring if necessary.
In extreme cases after long term storage bearings may need professionally reconditioning before installation.When unwrapping, care must be taken not to cut and damage the integral seals.
