Design Features
● Tapered Design: Tapered rollers run on tapered raceways, with all surfaces converging to one point on the shaft centerline. This ensures even distribution of load.
● Separable Structure: The inner assembly (rollers and cage) is separate from the outer ring. This allows for easier mounting and servicing, especially on large equipment where disassembly is tricky.
● Precision Movement Control: Within the specified axial clearance, the bearings limit axial play of the shaft or housing on both sides.
● Low Misalignment Tolerance: These bearings are not meant for significant shaft misalignment. The maximum allowable angle between shaft and housing is only 2 minutes, so alignment during installation is crucial.
Real Benefits For Your Operation
● Handles Combined Loads: One bearing can manage both radial load and bidirectional axial load, often removing the need for additional bearing sets.
● Easier Maintenance: The separable design means you can replace or service bearings without stripping down entire machines, saving downtime and labor costs.
● Rigid Construction: Built to resist shock loads, making them reliable for heavy machinery and harsh industrial environments.
● Long-Lasting Options: ZWZ offers multi-sealed versions of these bearings. These improved seals help keep contaminants out and retain lubrication longer, which can extend bearing life significantly in real-world applications.
