Pro-Series™ Bands

Pro-Series™ Bands

Enhanced Performance

Today’s engines and transmissions are smaller and more powerful than ever before. They require higher drum speeds, more horsepower, increased loading and higher energy absorption. High energy equates to extreme heat, which can degrade and destroy transmissions. Raybestos Powertrain has developed an affordable high-energy band that addresses this problem of high stress in small packages. The premium Pro-Series™ band is constructed of Kevlar® fibers along with solids and resins that enhance band performance. Pro-Series™ bands are the perfect upgrade for heavy duty, towing and high performance rebuilds. Notable applications include Allison LT1000, LT2000, LT2400 Series, Chrysler 48RE wide band, Ford 5R55W, and GM 4L60E.

Recommended Use:

Heavy duty, towing and high performance rebuilds.

The Science Behind Pro-Series™ Bands

Pro-Series™ Friction Material Characteristics

Tests were performed on OE automatic transmission bands using OE approved procedures for product qualification testing.

SAE J2487 - Stepped Power

Friction co-efficient vs. Unit Energy

Pro-Series Bands SAE J2487 - Stepped Power

The Raybestos OE Band material attains a high energy level in the stepped power test. The friction coefficient and E/M ratio (End-point Coefficient to Mid-point Coefficient) are maintained very well through each level completed.
The E/M Ratio is constant above 1.0 which represents a high pre-lockup (engagement) coefficient, enabling the ‘Slib and Grab’ action required for optimal band performance.

Durability Testing

Durability co-efficient

Pro-Series Bands Durability co-efficient

10,000 + cycles to evaluate the durability of the band.
Coefficient data is recorded at each 2000 cycle interval.
The trace shows excellent fade resistance with the overall coefficient fade over the life of the test (10,000 cycles) is less than 8%.
Average Wear (3 tests) of only 0.138 mm over 10,000 cycles.

Friction Band Evaluation Testing

Co-efficient profile

500 cycle test with Friction Coefficient recorded at the beginning and the end of the test, represented by the Blue and Red traces.
Higher density and higher temperature capacity than conventional tan torque converter liningsData is combined average of 3 tests with Raybestos OE Band Material.
The curve shows a positive increase in coefficient as a function of stop time which is a desirable function that enables a ‘Slip and Grab’ action for a holding clutch (band), and indicates that the Raybestos OE Band material is an excellent choice for bands.
