Description
Koyo Radial Needle Roller and Cage Assembly, Caged Round Bore Single Row, Series: WJ Inch Series, 2-1/2 in Bore, 2.8761 in OD, 1-1/2 in Width, For Shaft Diameter: 2-1/2 in, 83.2 kN Dynamic/173 kN Static Load, High Carbon Chrome Steel Bearing/Steel Cage, 4400 rpm Grease/6700 rpm Oil Maximum, -30 to 110 deg C
Features:
- Best used for applications that require maximum radial load capacity and a thin cross section
- Most sizes use a hardened steel cage (no callout)
- The housing bore and shaft must be hardened and machined
- Utilized design simplifies handling and installation while allowing for increased lube flow
- Split and segmented designs allows mounting at difficult positions on crankshafts and gear shaft
- Controlled contour rollers optimize contact stress distribution
- Special manufacturing processes help increase roller fatigue resistance and minimize axial drift effect in critical applications
- Optimized cage piloting geometry minimizes pressure velocity effects
- Sigma type cage assembly
