CZ 2009 – Switch over to New Force – ZKL presents its new standard of roller bearings 2 Meeting the Demands of Technically Advanced Clients ZKL pays proper attention to technical development of products and investments in new technologies in order to meet the demands of technically advanced clients. As a result of one of fundamental innovations in recent time is launching gradual production start of ZKL bearings of higher standard with NEW FORCE designation. By introducing the production of New Force bearings ZKL thus follows up with the already materialized innovation phase of spherical roller bearings with steel sheet and brass machined cages. This initiated process will result in serial production representing approximately 50 percent of total assortment of ZKL roller bearings in category New Force in year 2010. New Force bearings constitute a new generation of ZKL bearings. The application of these bearings brings longer service life of bearings, higher operation safety, prolongation of service intervals and thus a substantial reduction of operational cost for users. New Force bearings are designed for most challenging mountings in transmission boxes, in railway vehicles, presses, rolling mills, paper mill machines, pumps, machine tools, power units, in printing industry and similar. As a first complex series of New Force bearings there are being introduced on the market radial spherical roller bearings for heavy duty operating conditions where use of standard bearings with steel sheet cage is not recommended. These new ZKL bearings are in execution with prong-type brass machined cage (EMH version). 3 NEW FORCE – Product of ZKL Technical Advancement The attained parameters of New Force bearings represent the accomplishment of development activities of ZKL in the spheres of • Materials of roller bearings components • Cold rolling technology of bearing rings • Inner design optimization • Surface treatment of bearing components Thanks to achieved results ZKL is offering to its clients New Force roller bearings of high-level utility values: • High dynamic load rating • Low friction rate • Reliability in severest operating conditions High Durability of Bearings Dynamic load rating increased by 8 to 25 percent brings durability of bearings higher by 30 to 110 percent compared with existing execution. + 30 % to 110 % + 8 % to 25 % New Force Standard Standard Higher bearing durability Higher dynamic load rating Higher dynamic load rating enables clients to lay out smaller dimensions designs to carry identical load. Thus ZKL brings them chances to reduce total costing of installation as well as energy savings in operation. 22313EW33J Cr: 304 kN d × D × B ø 65 × ø 140 × 48 Mass 3,5 kg 22312EW33J NEW FORCE Cr: 304 kN d × D × B ø 60 × ø 130 × 46 Mass 2,8 kg 4 N ew Fo r c e Use of High Quality Bearing Materials Steels for bearing production comply with parameters of international standards set forth in CSN EN ISO 683-17 Standard “Heat-Treated Steels, Alloy Steels and Free-Cutting Steels, Part 17: Ball and Roller Bearing Steels”. For production of bearing rings and rolling elements high quality materials of carefully selected iron works is being used. Long-standing collaboration with suppliers guarantees permanent amelioration process of evaluating parameters of incoming materials. Bearings New Force are made of through-hardening bearing steel 100Cr6, 100MnSi6-4 or 100CrMo7. Determinant quality parameters of steel and its processing have influence on bearing utility values, namely its resistance to fatigue damage, abrasion resistance and dimensional stability. They are: • Chemical composition and heat treatment: Selection of bearing steel type and optimization of heat treatment conditions is being made in dependence on component dimension. Heat treatment technology of New Force bearings guarantees stable hardness values of bearing components in entire profile. Bearing components are heat treated to optimum material structure and hardness suitable for bearing use in service temperatures up to 200°C. Resulting material structure guarantees dimensional stability of bearing components throughout their service live. • Content of non-metallic inclusions – micro purity: Reduction of non-metallic inclusions content is a decisive quality parameter in bearing steel metallurgy advancement. For production of New Force bearings ZKL is using bearing steel with minimum oxygen content (5 to 10 ppm). • Sort of semi-finished product Bearing quality and its production economy is influenced by selection of semi-product. Forming degree and favorable contact angle of forming fibers toward raceway are parameters which positively influence resistance of New Force bearings against fatigue damage. Smith forging Machined forging or pipe Die forging Shaped cold rolled product 5 Technology of Cold Rolled Bearing Rings Basic research demonstrated the influence of material fibers direction to the contact area in respect of bearing service life. The most suitable arrangement of fibers is such when their direction is parallel to contact area. With increasing angle of fibers direction toward the contact area the service life lessens. The cold rolling technology brought to New Force bearings optimum material structure for gaining higher bearing durability.

It brings noise reduction and higher accuracy in bearing run. • Adjusted parts shape in rolling contact characterized by abutment parameter. Thus the contact tension course is favorably influenced and adverse sliding tension caused by slippage is reduced. • Spherical roller bearings are designed with inner ring without fixed center rib. This enables to use larger spherical rollers and progressive production technology. The standard serial production is further oriented to use steel sheet cages in EJ and CJ version as priority. • For very challenging operating conditions the design of spherical roller bearings is based on CJ and EJ version where steel sheet cages are substituted by one-piece prong-type machined brass cage EMH, centered on inner ring. The catalogue utility values of bearings with steel sheet cage are observed. • New Force radial spherical roller bearings in EMH version are being introduced on the market as the first, to be followed by radial spherical roller bearings in EJ and CJ version, spherical roller bearings of larger sizes and single row and double row ball bearings. 7 Special Surface Treatment of NEW FORCE Bearings Components In frame of innovation programs a new design execution of steel sheet cages for spherical roller radial and thrust bearings has been established. Cages are manufactured of steel sheet with surface treatment for improved sliding properties and reduced cage wear. Cages design execution enables better lubrication and extended bearing service life. Surface treatments of New Force bearing components represent proven method of improved bearing properties for specific mountings. The benefit of surface layers is a better lubricant retention in rolling contact, reduced friction, increased wear and corrosion resistance. We recommend to consult suitability of surface treatment for special running conditions with Technical and Consulting Services of ZKL. Design Tests The principal parameters of New Force bearings are designed in compliance with proven methodology of ZKL instituted on basis of international ISO standards and own know-how acquired by test results as well as by experiences in production and operation of ZKL bearings. Basic dynamic load rating C is specified in conformity with ISO 281 1990. Numeric values in table section are stipulated for New Force bearings in view of improved material properties and modern industrial processes. Basic static load rating Co is stipulated in conformity with ISO 76:1987 standard. Limiting speed frequency is specified in compliance with internal ZKL methodology. The designed parameters were verified by tests on ZKL testing stations. 8 ZKL Bearings Parameters Verification The parameters of ZKL New Force bearings are being verified by tests in frame of their development as well as by periodical quality evaluation in course of serial production. The tests are performed according to own methodology on testing benches of bearing testing laboratory of ZKL-Výzkum a vývoj, a.s. company, the member of Czech Testing and Laboratories Association CTLA. Tests results of bearings as well as of entering materials are analyzed and serve as basis for new design, technology and investment solutions. 9 Technical Support of ZKL Bearings Users For solution of clients’ needs the Technical and Consulting Services center (TCS) is fully at disposal. Its professionals are prepared to operatively solve requirements and questions of ZKL bearings users regarding rolling arrangement and mounting. TCS renders information to clients in the field of bearings, their accessories and tribology.
