INDRON® TSTN Water Lubricated Bearings are engineered to address the challenges of abrasive water environments, offering a superior alternative to Thordon SXL. Designed for interference press fit, tear resistance, and dry-start capability, these bearings deliver unmatched durability and cost efficiency for pumps across industries.
INDRON® TSTN Water Lubricated Bearings are advanced polymer alloy bearings specifically designed for pumps operating in water-lubricated systems. Key features include:
Material: Proprietary TSTN elastoplastic alloy with bonded self-lubricating microcrystals and extreme-pressure particles.
Design: Interference press fit compatibility for seamless installation.
Applications: INDRON® TSTN Water Lubricated Bearings are engineered for demanding environments in thermal power plants, hydropower systems, and industrial water management.
Superior Material Technology
Self-Lubricating Microcrystals: Bonded with long-lasting lubricating particles, INDRON® TSTN ensures low friction and high wear resistance, even in low-sediment water.
Dry-Start Capability: Operates without external water supply systems, simplifying pump design and reducing installation costs.
Tear-Resistant: Engineered to withstand abrasive particles and edge loads, preventing material degradation.
High Load Capacity
Dynamic Surface Pressure: Up to 10MPa, making it ideal for heavy-duty applications.
PV Value: Achieves 100MPa·m/s under water lubrication, outperforming traditional rubber and Babbitt alloy bearings.
Interference Press Fit Installation
Freezing Method: Recommended due to the high thermal expansion coefficient of INDRON® TSTN. Use liquid ammonia or dry ice for optimal results.
Pressure Installation: A viable alternative when freezing tools are unavailable (requires chamfering as per specifications).
Thordon SXL Replacement
Cost-Effective: Longer service life and lower maintenance costs compared to Thordon SXL.
Environmental Compliance: Eliminates oil pollution risks with water-only lubrication.
