How the NATR-10 model number is decoded

the 30 mm outside diameter runs on the track while the 10 mm bore takes the pin or shaft; the 15 mm overall width spreads the Hertzian contact over the outer ring published ratings C 6.44 kN and C0 8 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.81 is typical for support roller with flange rings, with inner ring executions fatigue load limit Pu 0.88 kN at 10 mm bore gives a specific load of 0.64 kN per mm; the limiting speed is 4,800 r/min the 15 mm width carries the load at 0.43 kN per mm of roller complement; section height 10.0 mm between bore and track surface determines the outer-ring bending stiffness mass 64 g over a 30x15 mm envelope works out to 0.142 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty with a 10 mm bore this is one of the smallest sizes listed; the reduced section height limits the outer-ring bending stiffness, so track alignment must be held closely reading NATR: needle roller support roller with integral flange rings; the 30 mm outer ring runs on the track while the flanges keep the roller centred without separate thrust washers typical applications include automotive welding jig positioners, conveyor transfer and diverting rollers and woodworking machinery feed rollers this size is commonly specified for automotive welding jig positioners and conveyor transfer and diverting rollers, where the 30 mm track diameter and 10 mm bore fit standard cam and rail geometries in woodworking machinery feed rollers the 30 mm outer ring provides the rolling contact while the inner ring bore simplifies mounting; the 64 g mass is low enough for rapid indexing cycles cage guidance (NATR) is less tolerant of shock than full complement (NATV); heavy impact can crack the cage and release rollers into the mechanism the flange rings are a press fit on the inner ring; excessive axial preload during mounting can shift them and alter the internal clearance

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the cage material is typically polyamide or steel; at temperatures above 100 degC polyamide cages soften and lose guidance function
• cage guidance (NATR) is less tolerant of shock than full complement (NATV); heavy impact can crack the cage and release rollers into the mechanism
• the pressed-on flange rings are not designed for continuous axial load — side thrust from a skewed track will eventually dislodge them
