BEARINGS

DuraBlue is a self lubricated composite bushing designed for use in highly loaded oscillatory applications such as found in rudder, pintle and stearing gear assemblies. DuraBlue needs no lubrication and is exceptionally wear resistant with an extremely long wear life. It has a low coefficient of friction value of 0.04 to 0.08, resulting in no stick-slip during operation. DuraBlue experiences virtually no swelling in seawater, and a very low thermal coefficient of expansion. Its proprietary fiber matrix greatly extends wear life and a self-lubricating formulation for dry running.

• No lubrication is required
• High load capacity
• Dimensionally stable
• Chemical and corrosion resistant
• Tolerant to edge loading
• Sizes available: 1? ? 42? (2.5 ? 107cm) outside diameter.

Nickel-Chrome-Boron (NCB) alloy hard coating resists abrasion and corrosion protecting the shaft made of conventional materials, extending its wear life by as much as 4-5 times.

• Nickel Chrome Boron Alloy
• Gives maximum protection for Rudder Stock and Tail Shafts
• Extends bearing and shaft life

Duramax DX490 Rudder Bushings are molded from a 70 Scale D Durometer, Nitrile Rubber Compound, formulated to withstand the rugged ?impact? service encountered in a ship?s rudder steering system. They possess high rigidity for maximum dimensional stability while still retaining a degree of resiliency to dampen peak shock loads. They are homogenous cylinders molded with longitudinal lubrication grooves.

• Grease, oil and water serve equally well as lubricants
• Resistant to deterioration by hydrocarbons, acids, salt water corrosion and electrolysis
• Supplied with molded I.D. and O.D. dimensions with ample material for machining
• Sizes available: I.D. from 1.45? to 9.11? (36.83mm ? 231.39)
• O.D. from 2.35? to 12.22? (59.69mm ? 310.39mm)

Flanged Bearings are centrifically cast naval brass featuring heavy metal wall and integral flange. Integral flange permits solid bolting of bearing to stern tube stuffing box. A machined male pilot on the integral flange mates with the female recess of the stuffing box. Shells are furnished un-drilled unless specified.

• Available in solid and split design
• Over 70 different sizes in stock
• Custom sizes available upon request
• For shaft sizes: 2-1/2? to 15? (63.50mm ? 381.00mm)

These Naval Brass Sleeve Bearings adapt equally well to strut and stern tube mounts, and often used effectively as rudder-stock and pintle bushings.

• Diameters are precision fitted to the shaft size with correct clearance for efficient water lubrication.
• Thin shelled units are available for struts of small craft.
• Over 100 different sizes in stock
• Available in inch and metric sizes
• Custom sizes available upon request
• For shaft sizes: 3/4? to 6-1/2? (19.05mm ? 165.10mm)

These Non Metallic Sleeve Bearings feature a structure of engineered reinforced thermoset plastic. The nitrile rubber polymer liner that is bonded to shell, is non-corrosive and inherently resistant to chemicals, oil and grease, as well as being anti-electrolytic.

• Lightweight
• Over 100 different sizes in stock
• Available in inch and metric sizes
• Custom sizes available upon request
• For shaft sizes: 3/4? to 6? (19.05mm ? 152.40mm)

Flanged Bearings are centrifically cast naval brass with an integral flange for bolting to stern tube or strut housing to retain bearing and prevent rotation in housing. Shells are heavy walled providing structural strength and can be step turned if desired. Shells are furnished un-drilled unless specified.

• Available in solid and split design
• Over 70 different sizes in stock
• Custom sizes available upon request
• For shaft sizes: 2? to 15? (50.80mm ? 381.00mm)
