BPW Type Trailer Equalizer Beam
Cast from high-grade nodular iron with integrated grease channels and hardened spring seat pads, our German-style equalizer beams cushion road shocks and promote even tire wear for heavy commercial trailers.
Product Overview
Our BPW Type Trailer Equalizer Beam is designed to function as the central articulation rocker arm within German-pattern mechanical suspension systems. Installed inside the center hanger, this dynamic rocker arm balances weight distribution between adjacent axles, preventing excessive frame twisting when tandem or tri-axle trailers travel over road depressions and speed bumps. It provides trailer factories, fleet maintenance depots, and axle wholesalers with an essential heavy-haul undercarriage component engineered for long-distance commercial freigh
Feature
Hardened Spring Contact Pad Design
The BPW Type Trailer Equalizer Beam incorporates curved, hardened seat channels at both ends to seat the leaf spring tips. This contoured contact area reduces localized friction as the leaf springs flex and slide during suspension movement, minimizing spring end grooving and extending the service interval of the entire spring pack.
Internal Lubrication Passages for Easy Maintenance
Featuring precision-machined grease grooves connected to standard zerk grease fittings, the central pivot hub stays thoroughly lubricated under extreme working loads. This continuous lubrication layer prevents pivot pin binding, dampens mechanical vibration, and reduces downtime for fleet mechanics during routine maintenance checks.
Quality Control & Production
Every production batch of our BPW Type Trailer Equalizer Beam is processed using high-precision horizontal boring equipment, automated shot-peening units, and induction hardening lines.
