Welcome to Linqing Xinshengdi Bearing Co., Ltd.
30216 Tapered Roller Bearing
- Dimensions: 80mm (d) x 140mm (D) x 28.25mm (T)
- Counteracts severe cantilevered loads from off-center weight.
- High-load density rollers maximize rolling surface contact.
- Resists abrasive dust infiltration under mixing drums.
Ready-mix concrete trucks depend on constant drum rotation while carrying heavily shifted, shifting payloads. The 30216 bearing is designed precisely to counteract this severe cantilevered stress. Supporting the main drum rollers at an 80mm shaft diameter, its steep conical contact angle evenly distributes both the heavy downward radial weight and the twisting axial torque, ensuring smooth, non-binding rotation even when the truck is traversing uneven construction site entryways.
