Feb 09, 2007 Made from clean bearing steel, Single-Row Cylindrical Roller Bearings are available 164 sizes in design variants NU, NJ, and NUP. Bearing cages are offered in roller-guided and outer ring-guided versions and are made from brass and polyamide. Optimized geometries of raceways and rolling elements maximize loading capacity, while modified cage design facilitates formation of lubricant film. Misalignments can be compensated through modified contact geometry and crowned inner raceways.

Jul 11, 2006 SKF® high-capacity cylindrical roller bearings feature low cross-section cage that eliminates risk of damage by roller-to-roller smearing. Cage design also increases lubrication by allowing room for oil passage, which lubricates contacts between rollers and raceways, provides cooling, and reduces risk of metal-to-metal contact. Optimized cross-sections of rings and rollers minimize potential for fretting corrosion, ring creep, and flange fracture.

Sep 30, 2002 Sealed angular contact spindle bearings have non-contacting seal that helps retain lubricant and protects against premature failure caused by infiltration of contaminants. Non-contacting nature of design allows bearings to operate at running speeds up to 1.5 M dN without any impedance normally caused by seal interference. Bearings are offered in high speed (small ball) and standard (large ball) versions with 15° or 25° contact angle.

Sep 30, 2002 Cylindrical roller bearings are single and double row spindle bearings with crown profile for optimized load distribution. Typically used in combination with double direction angular contact thrust bearings, they are suited for applications where combination of radial stiffness, high radial capacity and high precision support are required. Hybrid Ceramic (HCN) single row cylindrical roller bearing suits high speed floating bearing arrangement in milling spindle applications.

Aug 12, 2002 Fafnir® True High-Speed Sealed Bearings (THSS) feature non-contact dynamic seals which retain grease inside and keep contamination out. CERBEC® ceramic ball complement decreases friction in rolling contact area and lowers centrifugal forces. Integrated design helps prevent degradation of lubricant viscosity that could otherwise occur at temperatures above 160°F. Precision tolerances at ABEC9 (ISO P2) levels and 15° contact angle increase spindle rigidity.
