TL Series Spherical Roller Bearings

NSK has based its reputation on solving the most challenging industrial problems in ways that exceed customers’ expectations. Our innovative TL Series carries this tradition forward by providing outstanding performance under high temperatures.

High temperature processing and manufacturing environments, such as those in the dryer section, are especially vulnerable to work stoppages due to inner ring fractures. TL significantly reduce this risk with superior resistance to inner ring fractures while providing extended life and excellent dimensional stability.

• Special steel and surface hardening heat treatment strengthens the inner ring
against increasing hoop stress
• Superior raceway hardness combats contamination
• Excellent dimensional stability in high temperatures

• Enhanced inner ring strength
• Significantly improved bearing life
• Increased uptime and lower maintenance costs
• Fatigue life 2 times longer than carburized steel and 3.5 times bainite steel
• Fracture resistance up to 50% higher than bainite steel

SPHERICAL ROLLER BEARINGS FOR VIBRATING EQUIPMENT

NSK's vibrating equipment bearings are engineered specifically to withstand the high speed, shock loading, misalignment, and marginal lubrication conditions typical of the vibratory equipment found in the aggregates, mining & construction industries.

• High capacity design
• One-piece machined brass cage
• Guide ring
• Symmetrical rollers with contoured surfaces
• Special outside diameter tolerances and radial clearance
• Increased shock load protection

• Increased fatigue life
• A robust cage for heavy duty operations prevents cage fracture
• The ring guides the rollers to reduce wear and lowers internal temperature
• The symmetrical rollers increase limiting speed by reducing stress and temperature on the rollers and raceways
• More reliable fits and reduced risk of seizure
