Upgraded Explorer spherical roller bearings for vibratory applications from SKF, Lansdale, PA, have been newly engineered to provide increased performance and longer service life.
Typical applications include vibrating screens, compactors, road rollers, and similar end-uses that operate with high vibration and exposure to contamination, and/or poor-lubrication conditions. Because these bearings are designed to accommodate very heavy radial and axial loads, they’re also well suited for applications where misalignment or shaft deflections may occur.
Features and Capabilities
According to SKF, products in this Explorer spherical-roller bearing family are made from high quality, super-clean, and tough steel; benefit from an upgraded heat treatment; and integrate a special cage design. These combined features, the company says, offer a number of advantages beyond an extended service life (several times longer than other spherical roller bearings under typical heavy-duty conditions). They include:
- Lower operating temperatures for cooler and longer running;
- Improved resistance to wear and contamination;
- Excellent performance in high-speed applications;
- Reduced risks of fretting corrosion and induced axial preload;
- Extended re-lubrication intervals that reduce maintenance costs and boost safety.
The bearings are available in a wide range of bore sizes with increased dimensional precision, two hardened steel cages with an outer ring centered guide ring, and C4 internal radial clearance standard. Optional PTFE-coated cylindrical bores can be supplied to reduce fretting corrosion on the shaft. Custom products can be developed to meet the most demanding requirements.
