Hydraulic Breaker Side Plate Bolts & Bracket Bolts

SLYM MACHINERY manufactures and supplies premium hydraulic breaker side plate bolts (also known as bracket bolts) engineered for heavy-duty earthmoving and demolition applications. These high-tensile fasteners securely mount the breaker power cell inside its outer housing or bracket assembly, absorbing extreme recoil and transverse shear stresses during operation.

Precision-machined from 42CrMo alloy steel and subjected to controlled heat treatment, SLYM side plate bols deliver superior core toughness and exceptional fatigue resistance, preventing premature shear snapping and thread stripping under continuous shock loading.

1. Product Overview & Key Advantages

Hydraulic breaker side plate bolts are critical structural fasteners in breaker housing assemblies. Because bolt configurations, thread pitches, and shoulder lengths vary across breaker manufacturers, choosing the correct engineering specification is essential for equipment stability and job-site safety.

Key Features & Advantages:

• Premium 42CrMo Alloy Steel: Strictly manufactured using 42CrMo alloy steel to ensure optimal tensile strength and core toughness under high-frequency impact loading.

• Superior Shear & Wear Resistance: Engineered with hard-surface and tough-core mechanical properties to resist scissor-like shear forces at the housing junction.

• Complete Fastener Kits Available: Supplied as individual side bolts or complete mounting hardware packages, including heavy-duty 42CrMo hex nuts and OEM-specified wedge-locking washers (e.g., Nord-Lock®) to prevent vibration loosening.

• Global Brand Compatibility: Engineered to fit major hydraulic breaker brands, including Soosan, Furukawa and more.

• Precision Technical Matching: Free technical verification supported by SLYM engineers using your breaker model, part numbers, or physical measurements.

 2. Material & Manufacturing Standards

SLYM hydraulic breaker side plate bolts are crafted from high-grade 42CrMo alloy steel.

Unlike standard commercial-grade fasteners (such as 8.8 or 10.9 hex bolts), 42CrMo alloy steel combined with precise heat treatment ensures:

• High Core Toughness: Prevents brittle fracturing when subjected to heavy side-prying loads.

• High Fatigue Strength: Withstands millions of intense hydraulic recoil impacts without structural degradation.

• Thread Durability: Precision-rolled threads resist stripping and galling during installation and high-torque operation.

(Note: Specific mechanical properties, surface hardness, and tensile ratings can be provided along with relevant technical documentation or test reports upon request.)

3. Applications & Brand Compatibility

Side plate bolts are designed for heavy-duty hydraulic breakers installed on excavators, backhoes, and demolition rigs.

Because mounting configurations are model-specific, a replacement bolt must match the exact dimensions and strength grade of the original component. To help us confirm 100% compatibility for your equipment, please provide:

• Hydraulic Breaker Brand & Model Number

• Original Part Number (if available)

• Bolt Key Dimensions: Shank diameter, overall length, thread length, and thread pitch.

• Photos & Drawings: Clear photos of the worn fastener, mounting position, or technical drawing/sample.

4. Installation & Maintenance Recommendations

Proper installation and maintenance are essential to prevent premature bolt failure and housing damage:

• Pre-Installation Inspection: Check bolt threads, housing mounting holes, and mating surfaces for cracks, ovalization ("egg-shaping"), or heavy wear before fitting new bolts.

• Use Anti-Loosening Washers: Always install OEM-specified wedge-locking washers or stop plates to absorb intense recoil vibration.

• Apply Exact Tightening Torque: Tighten side plate bolts in a cross/staged pattern using a calibrated torque wrench according to the specific breaker model manual.

• Daily Torque Audits: Perform visual checks and daily torque verification before starting each shift.

• Investigate Repeated Failure: If bolts repeatedly loosen or snap, inspect the internal housing alignment and mounting hole conditions rather than simply replacing the fastener.
