RNAF Bearings Metric Series Are Designed For Machine Tools, Textile Machineries, Printing Machines And Other Mass-Production High Accuracy Motors And Components.
Machined Type Needle Roller Bearings consist of outer ring, inner ring and separable cage, without inner ring for long lasting durability. Radial clearance can be freely chosen by selecting and combining separable component parts. GTR series are full compliment bearings with mallet-shaped rollers that are guided by guide rail and groove to minimize skewing. Pre-packed lubricant is not provided, so proper lubricant must be applied when used. 0.2µmRa or less shaft surface finish and HRC 58 to 64 shaft hardness are recommended. Single row (RNAF) and double row (RNAFW) are available with the same sectional heights. Available dynamic load rating ranges from 2420 to 111,000. Static load ranges from 1950 to 306,000. Max speed/grease RPM ranges from 2250 to 42,500. Outer ring widths range from 8 to 60 mm. Other dimensions vary per model.
