Upgraded SKF Explorer spherical roller bearings for vibratory applications have been newly engineered to provide ideal performance and longer service life compared with conventional types. Typical applications include vibrating screens, compactors, road rollers, and similar end-uses operating with high vibration and exposed to contamination, and/or poor lubrication conditions. The bearings additionally are designed to accommodate very heavy radial and axial loads suiting applications where misalignment or shaft deflections may occur.
SKF Explorer spherical roller bearings are made from high quality, super-clean, and tough steel; benefit from an upgraded heat treatment; and integrate a special cage design. All combine to extend bearing service life several times longer than other spherical roller bearings under typical heavy-duty conditions, lower operating temperatures for cooler and longer running, improve resistance to wear and contamination, perform excellently in high speeds, and reduce risks of fretting corrosion and induced axial preload. The bearings further can extend re-lubrication intervals to reduce maintenance costs and improve 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.
