Machined Needle Roller Bearings Metric Series Are Suitable For Applications With Heavy Loads, Shock Loads And Oscillating Motions In Motors And Components.
Machined Type Needle Roller Bearings consist of a solid outer ring, rollers and retainer, without inner ring for long lasting durability. Feature low sectional height, large load ratings and high rigidity that can easily be used for light alloy housings. 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 except with double sealed bearings (suffix UU). Proper lubricant must be applied when used. 0.2µmRa or less shaft surface finish and HRC 58 to 64 shaft hardness are recommended. Available dynamic load rating ranges from 2420 to 409,000. Static load ranges from 1950 to 923,000. Max speed/grease RPM ranges from 660 to 48,000. Bore sizes range from 5 to 140 mm. Other dimensions vary per model.
