Custom Counterbalance Gas Spring Manufacturers and Suppliers

A counterbalance gas spring manufacturer designs components that offset the weight of a lid, door, cover, or panel so it opens with less force and stays controlled through its motion arc. Mansfield focuses on custom counterbalance and gas-spring alternative mechanisms, engineering the torque profile, materials, geometry, and production method around each OEM application.

Mansfield is not positioned as a standard catalog gas spring supplier. The company specializes in custom-engineered counterbalances, lift-assist mechanisms, spring counterbalances, hydraulic counterbalances, constant-force counterbalances, and gas-spring alternative assemblies. This is best for OEM programs where off-the-shelf hardware cannot meet packaging, cost, feel, durability, or motion-control requirements.

Mansfield serves residential and commercial appliance OEMs, automotive aftermarket manufacturers, medical casegoods companies, industrial OEMs, transportation programs, and specialty equipment manufacturers. Common applications include oven doors, washing machine lids, heavy access covers, deck lids, tonneau covers, medical cabinet doors, lab casework, industrial enclosures, and controlled drop-down panels.

Yes. Counterbalance engineering is application-specific, and Mansfield designs mechanisms around the required torque curve, panel weight, center of gravity, pivot geometry, motion arc, hold-open behavior, and target user feel. The team can prototype and test designs in-house to confirm force, torque, cycle life, and hold-at-angle performance before production tooling is released.

Mansfield supports OEM programs from approximately 5,000 components to 5,000,000+ components per program. Its Mansfield, Ohio operation ships more than 250,000 motion control components every week. The company uses progressive die stamping, single-stage tooling, flexible assembly, strategic inventory, and release-based delivery to support both specialty and high-volume production.

Pricing is quoted per program based on design complexity, materials, tolerances, tooling requirements, testing needs, and production volume. Mansfield applies value engineering to meet target unit economics while maintaining performance and reliability. Tooling, prototyping, engineering support, production validation, and ongoing manufacturing requirements are typically reviewed during the RFQ and design consultation process.

Yes. Mansfield provides production transition, tooling transfer, resourcing, and reshoring support for OEMs dealing with discontinued suppliers, closed factory divisions, unreliable offshore sources, or end-of-life supplier relationships. The transition can include tooling qualification, first-article inspection, production validation, and value engineering while preserving required form, fit, and function.

Mansfield manufactures domestically at 1776 Harrington Memorial Road in Mansfield, Ohio, with global delivery to OEM customers worldwide. The company also has global sourcing partnerships when a hybrid domestic-plus-offshore strategy is appropriate. Since 2023, Mansfield has been part of the Sabaf Group, expanding support for international appliance and component programs.
