Neutral - KJM716649/KJM716610/DFYA8 | Double Direction Taper Roller Bearing Units | 85 × 130 × 60 mm

Details

Neutral KJM716649/KJM716610/DFYA8 is a double direction taper roller bearing units with inner diameter 85 mm, outer diameter 130 mm and width 60 mm. Additional specifications include bore type CYLINDRICAL, cage STANDARD and lubrication STANDARD.

These bearing is an ultra-heavy load series double-row tapered roller bearing. It features a configuration, consisting of a single one-piece double inner race (cone) and two single outer races (cups). Unlike standard single-row tapered bearings that only manage thrust in one direction, the double-row layout allows this assembly to absorb high axial forces from both the left and right. The dual-row profile effectively resists tilting forces (moment loads), keeping shafts precisely aligned even under unequal torque distribution. It is traditionally supplied complete with an outer race spacer to create a factory pre-set internal clearance. Material : The bearing is manufactured from high-purity, case-hardened or through-hardened chrome steel alloy (typically Grade GCr15SiMn or standard 52100). Features are : Integrated Lubrication Grooves & Holes, Logarithmic Roller Profile, Minimized Operational Vibration, Power-Dense Internal Geometry, Extended Service Life, Lower Torque and Operating Temperatures. Applications : Metallurgical & Steel Rolling Mills, Pulp, Paper, and Forest Products, Cement and Aggregate Processing, Mining and Mineral Processing, Renewable Energy & Power Generation.
