FAQ1: What are the DC4930AVW Bearing Specifications?
The DC4930AVW is a specialized, full-complement cylindrical roller bearing (often used in heavy-duty automotive or industrial applications).
Type: Full Complement (No cage), which allows for the maximum number of rollers.
Dimensions: * Bore (d): 150 mm
Outer Diameter (D): 210 mm
Width (B): 60 mm
Load Capacity: Extremely high radial load capacity due to the lack of a cage.
FAQ2: What Applications are the DC4930AVW for the gearbox?
In gearboxes, this bearing is used because:
Space Saving: It provides a very high load rating within a relatively small boundary dimension.
High Torque: Full-complement designs are ideal for low-speed, high-torque shafts found in heavy machinery gearboxes.
Rigidity: It offers high radial stiffness, keeping gears precisely aligned under load.
FAQ3: How to Select Bearings for Heavy Loads?
When selecting for heavy-duty machines, follow these rules:
Go Full Complement: Choose a design without a cage if your speed is low, but your load is extremely high.
Verify Radial Clearance: For heavy loads that generate heat, C3 or C4 clearance is often required to prevent the bearing from locking up.
Check Surface Hardness: Ensure the raceways are case-hardened or through-hardened to at least 58-62 HRC to prevent deformation.
