Customer Needs and SKF Offer
Needs:
• Save total cost (OEM)
• improved value offer for endusers (OEM)
• Keep life cycle cost low(less maintenance) (EU)
Offer:
• Simplifies mounting
• Simplifies lubrication
2008-05-06 ©SKF Slide 7 [Code] SKF [Organisation]
Offer
Features
Integrated customized sealings engineered for longtime grease lubrication
Grease selection to meet longtime grease lubrication
Function
Proper sealing function
Avoid contamination to enter bearing
Avoid grease leakage
2008-05-06 ©SKF Slide 8 [Code] SKF [Organisation]
Offer
Benefits
milestone to achieve "oil-free press"
longtime grease lubrication possible
simplification of central lubrication system possible (pump, pipes, filters)
grease provides longer lifetimes than oil (oil needs to be changed frequently)
grease, seal- and bearing design dimensioned for long-time grease lubrication
optimized engineering/design
less re-greasing less maintenance activities
2008-05-06 ©SKF Slide 9 [Code] SKF [Organisation]
Offer
Benefits (continued)
SKF competence in bearings, seals, lubrication, lubrication system bundled
less single components, one supplier for whole system, easier logistics
no oil leakages no pollution of print medium, clean machine operating reliable
decrease total cost
improved value offer for endusers
keep life cycle cost low
2008-05-06 ©SKF Slide 10 [Code] SKF [Organisation]
Offer
Features
Integrated customized tapered sleeve engineered and manufactured for easy mounting
Function
By moving the tapered sleeve in axial direction onto the tapered seating the outer diameter expands
Thus eliminates the initial clearance between sleeve and side frame bore
Tight fit between bearing system and side frame will be achieved
2008-05-06 ©SKF Slide 11 [Code] SKF [Organisation]
Offer
Benefits
no selective choice bearing outer diameter with side frame bore necessary anymore
each individual bearing fits to each individual side frame bore
in case of bearing replacements interchangeability is given
simplified machining of side frame bore
in case of intended tight fit between OD and side frame no cooling of bearing necessary anymore
2008-05-06 ©SKF Slide 12 [Code] SKF [Organisation]
Offer
Benefits (continued)
guaranteed tight fit easy to achieve
less mounting time
easier logistics
decrease total cost
2008-05-06 ©SKF Slide 13 [Code] SKF [Organisation]
Offer
Features
Integrated customized short taper joint engineered and manufactured for easy mounting
Function
Enable connection to printing cylinder
2008-05-06 ©SKF Slide 14 [Code] SKF [Organisation]
Offer
Benefits
Easy and time saving connection to printing cylinder, less mounting and dismounting time
Less time consuming when changing printing cylinders
Bearing system fully interchangeable
No preassembly of inner ring onto tapered shaft seating necessary anymore
2008-05-06 ©SKF Slide 15 [Code] SKF [Organisation]
Offer
Benefits
Defining of radial clearance/preload during preassembly not necessary anymore (is done by SKF)
easier logistics
decrease total cost
