XR/JXR cross tapered roller bearings are compact,high-precision components that use tapered rollers arranged in a crisscross pattern to handle heavy loads from multiple directions in a small space.
The bearing comes with integrated shoulder positioning structure equipped with standard mounting holes and greasing holes.Precision grades cover P5,P4 and ultra-precision P2.Inner diameter ranges from 150 mm to 2463.8 mm,outer diameter spans 230 mm to 2819.4 mm and cross-section height varies between 30 mm and 114.3 mm.
Bearing rings and rolling elements can select GCr15SiMn high carbon chromium silicon manganese steel or SUS440C stainless steel for corrosive surroundings.Cage choices include high-strength brass,phenolic resin and custom dedicated composite materials.Multiple sealing solutions are available.Open type suits clean high-load medium-low speed working conditions and requires regular external lubrication.Contact rubber seals UU or U provide dustproof and splash-proof performance for dusty humid industrial sites.Labyrinth seals ZZ offer superior shielding for heavy-duty machinery with high impact interference.
Standard product delivery takes 10 to 20 working days.Custom service supports non-standard dimension adjustment,tapered roller angle modification,mounting hole and shoulder parameter customization,corrosion resistant material upgrade and special lubrication for ultra-high or low temperature conditions.
Tapered Roller Geometry:Unlike standard crossed roller bearings that use cylindrical rollers,XR/JXR bearings utilize steep-angle tapered rollers alternating at 90°inside V-groove raceways.
True Rolling Motion:The tapered geometry eliminates differential slip across the roller contact line,reducing friction torque,wear,and heat generation at elevated speeds.
Maximum Tilting Moment Rigidity:Steep contact angles and line contact give XR/JXR bearings the highest overturning moment stiffness of any single-row rotary bearing structure.
Compact Cross-Section for Heavy Loads:A single XR/JXR bearing replaces traditional two-bearing mounting arrangements,saving axial height and structural weight.
Precision Preload Adjustment:Manufactured with split ring designs to allow fine adjustment of preload for zero backlash and sub-micron rotational runout.
High Rotational Speed Capability:Lower frictional drag from tapered rolling alignment permits higher speed limits compared to standard cylindrical crossed roller bearings of similar size.
