Product Name: RU297G RU297X Cross Roller Excavator Slewing Bearing, Heavy-Duty Slewing Ring
RU297G/RU297X are heavy-duty crossed roller bearings specifically designed for excavator and construction machinery turntables. Adopting an integrated inner and outer ring structure with pre-drilled mounting holes, they can be directly bolted without additional flanges or supports, ensuring easy installation and strong adaptability to installation errors. Featuring a 90° crossed cylindrical roller layout, a single bearing can simultaneously bear radial load, axial load and large overturning moment, with rigidity 3-4 times higher than that of traditional bearing sets, effectively ensuring the smooth rotation of excavators and resisting impact loads during digging operations.
