Overview

ACL supplies an extensive range of automotive engine bearings for niche applications and the aftermarket worldwide. Although ACL manufactures several different materials to suit various applications, tri-metal copper lead DuraglideTM F780 is considered to be the premium material and is used extensively in many aftermarket applications.

The material provides the widest range of load carrying capacities with excellent durability, making it ideal for connecting rod and main bearings in passenger cars using gas and diesel, and high performance engines.

ACL DuraglideTM F780 bearings are a tough solution for a tough problem. Engine re-builders are confronted by an increasingly diverse range of engines with a wide range of OEM bearing types. While these OEM bearing types and materials may be well suited to engines finished to the exacting specifications of modern engine manufacturers, they are often ill suited to used engines reconditioned and rebuilt in a flexible workshop.

The ACL F780 tri-metal material system at the heart of DuraglideTM 780 bearings has been designed for and proven in a wide range of engine applications, both OE and aftermarket. The complimentary layers ensure that superior strength is available from the steel and sintered copperlead-tin lining, accompanied by the excellent anti-seizure properties of the lead-tin-copper overlay. For the engine rebuilder this means confidence – the confidence provided by a tough bearing capable of great performance whether fitted in a garage or precision workshop.

ACL DuraglideTM F780 bearings are precision manufactured to a wall thickness tolerance of ±.00026″ giving the engine builder close control of vertical oil clearance. For performance engines the extra build quality provided by tight clearance control can make all the difference.

Bearing Construction
1 - Steel strip onto which is added powdered copper-lead-tin metal alloy. The strip is sintered and compressed to bond the alloy to the steel backing.

2 - ACL sintered copper-lead-tin alloys provide a tough structure capable both of resisting high compressive loads and providing excellent adaptability.

3 - A lead-tin-copper overlay is applied to copper-lead-tin bearings produced by ACL. It is necessary however, to include a nickel intermediate layer (barrier plate or dam) to preserve the optimum metallurgy of the overlay under all operating conditions. ACL’s superior quality construction and control in electroplating eliminate potential overlay flaking.

4 - The lead-tin-copper overlay used by ACL consists of approximately 90% lead, 9% tin and 1% copper. Overlay thicknesses are nominally .0005″ – .0007″ for most automotive applications. TM

DuraglideTM F780 – the only solution when quality counts.

Bearing Type Characteristic DuraglideTM F780
Strength
Ability to assume prolonged, high fatigue loads.
Babbitt overlay (<20HV) is supported by a strong copper lead alloy (>50HV) in turn supported by the steel backing.
Strength is high as long as the overlay is thin (<.0008″).
Anti-Seizure Conformability
Ability to adapt to assembly and misalignment errors.
Very soft Babbitt overlay readily adapts. Copper lead alloy has
moderate conformability and helps to adapt where shape errors are significant.
Compatibility
Ability to accommodate shaft to bearing contact through thin oil films.
Crankshaft journal finish is the dominant factor. Contact with the
surface results in adaptation through wear of the Babbitt layer with no damage to the shaft.
Emergency Running
Ability to continue operation during
temporary oil film breakdown.
The lead in the Babbitt and copperlead alloy has natural lubricity and can function as a dry lubricant. The low melting point on the alloy also allows it to provide a temporary liquid lubricant.
Anti-Wear
Resistance to abrasion by shaft and dirt.
Babbitt alloys are prone to wear (see above), however the alloy composition is carefully controlled to optimise the strengthening effects of copper and minimising the wear potential.
Embeddability The soft Babbitt readily absorbs all kinds of dirt particles up to .0006″ without damage. Larger particles are adequately accommodated by the underlying layers.
Anti-Corrosion Tin content in both the lining and overlay alloys provides protection from chemical attack.
Applications DuraglideTM bearings provide a high combination of high strength and the ability to withstand harsh and demanding operating conditions. This makes them ideal for performance engines and rebuilds.

The simplest way to facilitate payment is via Mastercard, Visa, or Paypal via the Checkout process.

Please contact us if yous wish to pay via direct deposit and then we can supply our Account and BSB details.

If paying by bank deposit, please ensure you have your reference of your payment with your eBay user ID so we can identify the payment as yours. Failure to correctly reference your payment will cause a delay in our system which will ultimately delay the shipment of your order.
We check our bank accounts daily so as soon as your payment has cleared, we will start processing your order.

Our stock levels can change at any time. An order is only complete once payment has cleared. To prevent missing out, it's best to pay as soon as possible. Once a payment has cleared, 90% of products are dispatched within 1 business day, however please see our shipping page for estimated shipping times by state. Wedding Wish is not liable for any unidentified payments or delays of delivery due to failure to follow instructions during checkout.

For all payments outside of eBay, please ensure you send us the reference you used, the day and time you paid, and the amount deposited.

As always, if you have any questions, please get in contact with our Customer Service team who are more than happy to help.

We are happy to combine shipping on any orders. Individual listings with combined shipping will automatically calculate on checkout. When buying from multiple listings, please message us prior to purchase to confirm postage rates, be sure to include your postcode for accurate quoting and the items you are after. Express post is available on request for most orders, please note handing times will usually still apply.

Pre-arranged pickup is available from our warehouse in Dingley Village, Victoria. Please note that a handling time will still apply. Please call ahead or email us to ensure item is available for pickup.

POSTAGE & DISPATCH

After payment is cleared 90% of all items are dispatched within two business days, however please see below for estimated delivery times by state. Your item will be sent via courier or Australia Post depending on its size and weight.

Where goods are sent through Australia Post, the buyer may receive a knock on the door or a card in their letterbox indicating their item is available for pickup from their local post office.

A re-delivery fee will be charged to buyers for items that are undeliverable and/or returned due to incorrect delivery address or unsuccessful delivery.

Buyers have the full responsibility to provide us with the correct delivery address and mobile phone number on the checkout page before payment. Any changes to address after checkout will not be considered as valid.

Our staff work tirelessly to ensure customer satisfaction however we understand that on occasion issues do arise. If you have a problem with your purchase please contact us PRIOR to leaving feedback and we will do our best to rectify the situation.

Claims entered directly via this method will be given priority.

The fastest and best way to contact us is through the eBay messaging system. If you contact us out of eBay we may not see your message and our support team will be much slower in dealing with your issue. Thank you for your business!
