SAF-Holland, a global manufacturer of trailer suspension and axle systems, truck suspensions, fifth wheels and other products, launched its P89 Air Disc Brake Series Thursday at a product showcase in Grand Rapids, MI.
The company says the value and premium-level P89 products are designed with commercial fleets in mind and provide "superior braking performance, extended service intervals, and ease of maintenance."
The P89 Series comes in New P89 and P89 Plus models. The base model New P89 can be customized to suit specific fleet needs at a significantly lower price point — around 40% — than previous generation air disc brake systems.
SAF-Holland has leveraged their global supplier network to create economies of scale that drive down the cost of technology. We are able to pass this cost savings to our North American fleet customers and for the first time put air disc brake technology within reach of fleets large and small," said Jeff Talaga, vice president of sales and strategic development, Americas for SAF-Holland, Inc.
The P89 Plus is a premium package that includes a 7-year maintenance-free bearing system and premium rotors that the company says will provide a significant reduction in the total cost of ownership. Available on the SAF CBX air ride and ULX spring ride suspensions, the P89 Series "provides advantages of air disc brake performance to nearly all fleet operations, whether high mileage long haul fleets or demanding vocational trailer applications," according to SAF-Holland.
At the heart of the New P89 air disc brake is the proven SAF SBS 2220 caliper and 430mm diameter heavy duty vented rotor. The dual-piston SBS 2220 caliper applies a more even pressure pattern across the brake lining than competitive single piston designs, the company explains, while the 430mm diameter x 45mm thick rotor provides 30% more wear volume than competitive designs.
The New P89 features a "robust" 3.5-in. diameter parallel spindle or an optional lightweight taper spindle configuration that reduces weight by 10 lbs. per axle and uses industry standard bearings and wheel seals to reduce maintenance costs. Backed by a 5-year warranty, SAF-Holland says the New P89 sets a new industry standard for value in air disc brakes.
The P89 Plus comes with a 7-year maintenance-free bearing system that uses large 89mm front and rear bearings individually sealed and lubricated with high temperature long life grease.
SAF notes that the design completely eliminates traditional wheel seals, a common source of premature wheel-end failure. Precision bearing spacers are installed between the inner and outer bearings to precisely control bearing pre-load for maximum life — the company says extensive product testing has shown the P89 Plus bearing system provides four times better bearing life.
The unique bi-metallic design of the SAF INTEGRAL rotor included on the P89 Plus allows the rotor to expand and contract in a radial direction that keeps the braking surface flat and eliminates the "umbrella effect" that affects conventional rotors.
Backed by an industry-leading 7-year warranty, the P89 Plus "provides the ultimate in braking performance and ease of maintenance for a low total cost of ownership," SAF-Holland states. "With our commitment to design and develop products that better serve our fleet customers with leading technology, SAF-Holland is pleased to introduce the P89 Series that outperforms the competition in superior braking quality and total cost of ownership," said Talaga.
