Aqualube Catalog

Product catalog summary

Product Overview: The Aqualube range of rubber-sleeved bearings by Michigan Wheel USA is designed for marine and industrial applications. These bearings feature a specially formulated nitrile rubber that is resistant to chemicals, oil, abrasion, and wear. They are available in various shell materials, including brass and phenolic, and can accommodate shaft diameters from 1” to 10” and metric sizes from 20mm to 260mm.

Principle of Operation: Aqualube bearings utilize the natural resilience of rubber and water as a lubricant to absorb shock, vibration, and noise. The unique shape of the bearing creates a hydrodynamic water wedge between the shaft and bearing, reducing friction and preventing direct contact.

Construction: The bearings are molded from oil and chemical-resistant nitrile rubber, bonded to shells made from marine bronze or phenolic material. The smooth surface of the rubber lining indicates high quality.

Abrasion Resistance: The design allows abrasive particles to be flushed out, reducing wear in environments with suspended particles like sand.

Operating Parameters: Aqualube bearings operate at speeds from 100 to 6,900 feet per minute. For speeds outside this range, consultation with Michigan Wheel Marine is advised. The bearings have a Shore hardness of 70±3 and operate in temperatures from -13°F to 185°F.

Tolerances: The document provides detailed tolerances for various sizes, indicating precision in manufacturing.

Inspection and Quality Assurance: Each bearing undergoes a 100% inspection for dimensional accuracy, rubber hardness, and bond integrity before shipping.

Recommendations: Bearings should be inspected for wear during vessel maintenance, especially in shallow or contaminated waters. Forced water flow systems are recommended for bearings with marginal water flow or high loads.

Contact Information: Michigan Wheel Marine has locations in the USA, Europe, and the Middle East, providing contact details for inquiries and support.

Construction of AQUALUBE Bearings: Abrasion Resistance: Aqualube bearings are molded from a specially compounded oil and chemical resistant nitrile rubber. The nitrile rubber displays an excellent resistance to wear and abrasion and is also tough and durable. Bonding techniques developed by Michigan Wheel ensure that the strength of the bond to the shell is at least equal to the strength of the rubber itself. The finished product has a smooth, shiny surface to the rubber lining which, when compared with similar products on the market, provides visual testament to the quality of the bearing. Aqualube...
