Shear Spring (Shock Absorber Block) for screening equipment

NMS Shear Spring (Shock Absorber Block) - Premium Screen Accessory for Optimal Performance

As a genuine accessory exclusively designed for NMS (Nanchang Mining Machinery) vibrating screens, the NMS Shear Spring (also known as Shock Absorber Block) is engineered to deliver uncompromising stability, durability, and shock absorption—critical for maximizing the efficiency and lifespan of your screening equipment in harsh mining and industrial environments.

1. Product Overview: Core Component for Screen Stability

Vibrating screens rely on consistent, controlled vibration to separate materials, but excessive shock and vibration not only degrade screen performance but also accelerate wear on key components (e.g., screen decks, motors, frames). The NMS Shear Spring acts as the "vibration buffer" of the system, absorbing impact loads, reducing noise, and maintaining optimal vibration frequency—ensuring your NMS screen operates smoothly even under heavy, abrasive material loads.

Perfect Compatibility: Tailored to fit all mainstream NMS vibrating screen models (including linear vibrating screens, circular vibrating screens, and high-frequency screens), this shear spring replaces generic alternatives with a precision-machined design that matches NMS’s originalequipmentspecifications(OES).

2. Key Features & AdvantagesHigh-Quality Material Selection

Crafted from reinforced synthetic rubber composite with embedded high-tensile steel cores, the shear spring combines excellent elasticity, tear resistance, and compression strength. It withstands extreme temperatures (-30°C to 80°C), corrosive dust, and moisture—ideal for mining, quarrying, and aggregate processing sites.

Optimized Shock Absorption Performance

The unique "dumbbell" cross-sectional design and precision-molded structure ensure uniform force distribution. It effectively reduces vibration transmission to the screen frame and foundation by 30-40% compared to standard springs, minimizing equipment fatigue and extending the service life of adjacent components (e.g., bearings, motors).

Long Service Life & Low Maintenance

With superior anti-aging and anti-fatigue properties, the NMS Shear Spring maintains stable performance for up to 2-3 times longer than non-genuine alternatives. Its wear-resistant surface reduces the need for frequent replacements, lowering downtime and operational costs.

Easy Installation & Replacement

Designed with NMS’s original mounting dimensions, the shear spring can be installed without modifying the screen’s structure. The lightweight yet robust design simplifies on-site replacement, saving maintenance time and labor.

3. Application Scenarios

The NMS Shear Spring is a critical accessory for NMS vibrating screens used in:

Mining (coal, iron ore, copper ore, gold ore) screening

Quarrying (ced stone, gravel) classification

Aggregate and sand processing

Industrial waste sorting

Construction material screening
