Better Performance

Thordon SXL has a lower modulus of elasticity (440 MPa or 68,817 psi) than other non-metallic bearings, resulting in significantly increased vibration dampening, accommodation of edge loading, and better impact resistance than other non-metallic materials.

• Industry-leading wear life guarantees.
• Tolerance to edge loading.
• Wet or dry operation eliminates the use of grease.
• Transient shock loading absorption.
• High abrasion resistance.
• Quick delivery.

Easy to Machine & Fit

Thordon SXL bearings are easy to machine and produce no dust. In comparison, other non-metallic materials require dust extraction and tight machining tolerances that may result in product rejection or repair delays.

With Thordon SXL, machining tolerance is less critical and because of the relatively large interference on the bearings, it is usually possible to adjust dimensions to compensate for small machining errors.

HIGH PERFORMANCE BEARINGS & SEALS

Zero Pollution Bearings & Seals

Thordon SXL rudder bearings offer low friction, operating pressures up to 12 MPa (1,740 psi), and do not require grease or greasing systems. Thordon SXL can also withstand high shock loads and edge loading.

In addition to SXL pintle, stock, and carrier disc bearings, HPSXL TRAXL or ThorPlas-Blue can be specified in steering and linkage applications, as well as fin stabilizers. Both products operate grease-free – saving you time, money and the risk of pollution.

To complete the package, Thordon offers self-lubricating rudder stock seals that provide positive sealing and exceptional wear life.

Thorseal Rudder Stock Seals

• Prevent ingress of water into the hull.
• Manufactured from tough, self-lubricating Thorseal polymer.
• Designed to accommodate larger bearing clearances and movements inherent to rudders.
• High performance positive sealing and long wear life.
• Standard seals available for 200 mm (8”) to 1,200 mm (47”) shaft diameters.
• Special designs available to solve difficult sealing challenges.

Thorseal Hydraulic Seals

• Keep abrasives away from bearing surface.
• Pressures from 0-100 MPa (0-15,000 psi).
• Tough – won’t cut or tear.
• Low friction and self-lubricating.
• Long wear life and reduced maintenance costs.
• Can be custom designed to solve difficult sealing challenges.

ThorPlas-Blue Steering & Linkage Bearings

• Engineered thermoplastic for high pressure applications to 45 MPa (6,527 psi).
• Wet or dry operation.
• Very low wear in non-abrasive environments.
• Lifetime lubricated homogeneous polymer.
