Version 04.2016 NKE AUSTRIACompetence in bearings for agricultural machinery
Content • NKE standard bearings • NKE special bearings • Examples of application of NKE products in agricultural machinery • Reference list
NKE standard bearings • Wide range of standard bearings either from stock or with short lead-time • Internationally standardised – excellent availability, economical, 100% interchangeable with leading brands • Covers most industrial applications
NKE special bearings • In some cases, customers need special solutions for their particular applications • With decades-long experience in the bearing industry, NKE engineers are capable of providing you with rapid, practical and creative custom-made solutions • Advantages of special bearings: • Tailor-made for your applications • In many cases lower LCC due to better performance, lower maintenance costs, better use of available space, possibility of integration of neighbouring parts, etc. • Secured spare parts business
Reference: Equipment manufacturer (DE) • Customer profile: • The company is a well known manufacturer of agricultural machines; e.g. sowing and soil cultivation machines
Reference: Equipment manufacturer (DE) – 1 • Application: • Disc harrows • Bearing arrangement for double discs blades • Customer requirements: • Stiff bearing arrangement to accommodate high tilting torques • Optimal sealing of bearings
Reference: Equipment manufacturer (DE) – 2… continued • NKE solution: • Special double row angular contact ball bearing with 60° contact angle and split inner ring • Preloaded bearing and special grease filling combined with a RSR sealing • Advantages: • Maximum supporting width due to large angle of contact • High thrust load capability • Ready for mounting unit
Reference: Equipment manufacturer (DE) – 2 • Application: • Rotary harrow • Bearing arrangement for the rotor shaft • Customer requirements: • Reduction of part numbers • Optimization of load carrying capacity and sealing
Reference: Equipment manufacturer (DE) – 2 • Application: • Short disc-harrow • Bearing arrangement for the hollow discs • Customer requirements: • Robust bearing design to stand high tilting torques and shock loads • Solid sealing and lifetime greased bearing units
Reference: Equipment manufacturer (DE) – 2… continued • NKE solution: • Special deep groove ball bearing with integrated shaft seal and felt sealing • The second bearing is a standard 6308-2RS2 • Advantages: • Easy logistics and assembly – one unit instead of previously 4 pieces • Bearing and sealing have been adopted to the available mounting space • Cost effective solution
reference: Equipment manufacturer (DE) • application: • Sowing machine “Solitair” • Bearing arrangement for the double disc coulters • customer requirements: • Stiff bearing arrangement to stand high tilting torques • optimized sealing solution
Reference: Equipment manufacturer (DE)… continued • NKE solution: • Special double row angular contact ball bearing with axial preloading and additional sealing • Advantages: • Maximisation of bearing lifetime • Exact positioning and guiding of the disc blades due to a robust bearing design • Optimization of the sealing
Reference: Equipment manufacturer (GB) Customer profile: A family owned business founded in 1973, specialised in sowing machines Application: Bearing for double disc culture of a drilling machine Customer requirements: Stiff arrangement to accommodate radial and axial shock loads Best possible bearing seal against highly dusty environment
Reference: Equipment manufacturer (GB)… continued NKE solution: Paired tapered roller bearing adjusted with spacer rings in back-to-back arrangement Pre-lubricated with high performance grease and sealed with rubber lip seals on both sides and additional labyrinth seal on the critical outer side Advantages: High load carrying capacity of tapered roller bearings High stiffness due to back-to-back arrangement Optimum protection against dirt and dust due to complex sealing
