1 Spheical Rolle Beaings NSKHPS, edefining the standad.

2 Continually developing poducts with geate stength and highe accuacy, NSK s new NSKHPS fully incopoate the advantages of NSK s woldclass design, mateials, and manufactuing technology, setting a new standad fo beaings. Mateial State-of-the-at mateial technology though detailed analysis of aw mateial Design Exclusive NSK design though advanced analytical technology Manufactuing The most advanced poduction system guaantees outstanding quality contol 1 2

3 High pefomance in divese applications with educed maintenance costs and moe compact design NSKHPS spheical olle beaings meet the needs of vaious equipment fo components with educed maintenance costs and unsupassed functionality. By taking full advantage of NSK s wealth of expeience and expetise, NSKHPS spheical olle beaings ealize unpecedented enduance and high limiting speeds to suppot downsizing while at the same time impoving pefomance and lengthening equipment opeating life. Just what you would expect fom NSK, the leading beaing company. Featues of NSKHPS Spheical Rolle Beaings Life 2 times the opeating life Limiting Speed 20% highe Long Life Lowe Maintenance Cost Maintenance costs ae an impotant facto in educing total equipment costs. NSKHPS spheical olle beaings ealize twice the opeating life of conventional poducts, and longe opeating life leads to lowe maintenance costs. Flexible Applicable to a vaiety of applications With impoved cage esistance to wea at highe speeds ove longe peiod of opeation, NSKHPS spheical olle beaings delive high pefomance to a vaiety of applications. Compact Contibuting to equipment downsizing Achieving longe opeating life can be ealized togethe with the selection of smalle beaings. NSKHPS spheical olle beaings allow compact design fo vaious equipment, theeby suppoting the demand fo downsizing. 3 4

4 Long opeating life educes maintenance cost NSKHPS spheical olle beaings demonstate twice the opeating life of conventional EA Seies beaings fo longe equipment opeating life that lowes maintenance costs. The CD Seies compises NSK old-type standad beaings with a pessed steel cage. Life Compaison NSKHPS EA CD Life 2 times the opeating life Limiting Speed 20% highe High-speed, long-tem opeability povides inceased flexibility acoss a wide ange of applications. NSKHPS spheical olle beaings exhibit damatically educed cage wea at highe speeds ove longe peiods of opeation. As a esult, limiting speeds ae inceased to povide geate flexibility acoss an extensive ange of applications. Limiting speed NSKHPS EA CD 5

5 Innovative design dawing upon a vaiety of technologies leads to high pefomance in next-geneation poducts Innovative design developed though enhanced stuctual analysis The NSKHPS cage incopoates a olle guide function in place of a guide ing. Eliminating the guide ing and optimizing the design of the inne and oute ing configuation facilitates the placement of additional, lage olles. Optimized design fo the intenal specifications and impoved pess technology geatly incease load capacity, and ealize longe life. Special suface teatment futhe stengthens the cage, educing wea, heat and fiction; it also allows fo highe limiting speeds. Cage Guide ing NSK old type beaing Cage NSKHPS Beaing Inteio Design Compaison Elimination of the guide ing allowed fo a design change that impoves cage balance and stength. Adoption of state-of-the-at mateials NSKHPS spheical olle beaings ae made fom NSK s high-cleanliness Z steel. This steel featues geate fatigue stength. In addition, special suface teatment makes it moe esistant to wea and moe duable in a vaiety of applications. Cage design featues stonge esistance to wea By utilizing the space gained fom eliminating the guide ing and impoving the design though advanced stuctual analysis, cage stength has been inceased damatically. The highpecision olle guide function in place of the guide ing, united with a special suface teatment, stengthens the cage against wea and inceases the limiting speeds.
