Product Description Cylindrical Roller Bearings probably have the simplest construction in the roller bearings category. These bearings are suitable for carrying relatively higher loads, at high-speed applications. The rollers of C&H cylindrical roller bearings are key components. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and optimizes rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability and a greater insensitivity to misalignment. These bearings are suitable for applications involving light axial loads, specifically where accurate alignment of shaft is difficult. Cylindrical Roller Bearings available with two bore types, i.e. cylindrical and taper. Their cages are made of either pressed steel or brass material. Features C&H cylindrical roll bearings have the following design features: 1. Optimized design in ribs and rollers to enhance the axial load capacity 2. Optimized design in the geometric surface between rollers and raceway to balance the radial load distribution 3. Limit the width of raceway undercut, increase the contact area between raceway and rollers and enhance the radial load capacity 4. High standard material, strictly control the element content, e.g. Ti<30ppm 5. Low noise design, reaches to V1 grade noise level, contributes to the quieter running of automobile engine and gearbox. C&H can offer the following variants: Cylindrical Roller Bearings (Pressed Steel Cages) Single Row type – N, NF, NJ, NU and NUP series Double Row type – NN and NNU Series (details available on request) Four row for rolling mill -FC, FCD and FCP series Higher load capacity design – E type Single row full complement - NCF and NJG type Double row full complement – NNF Four row full complement With snap ring groove With snap ring groove and snap ring With C2, CN and C3 radial clearance Standard precision grade P0 and higher precision grade P5, P4, UP, P2 Pressed steel, machined brass, riveted steel cage, Polyamide cage Cylindrical and taper bore Application Wide application in general and precision required reliable, durability and high performance such as Steel industry Mining & Construction Papermaking Machinery Wind Turbines Machine Tools Gear Boxes & Reducers Electric Motors Pumps & Compressors Injection Molding Machines Automobile and Motorcycles Railways
