Fixed side plate: Side bolts are mainly used to fix the side plate of the crushing hammer and closely connect the side plate with the main body.
Materials for Side Bolts:
Side bolts are usually made of high strength alloy steel, common materials are:
42CrMo: This material has high strength, high toughness and good wear resistance after heat treatment (such as quenching and tempering).
40Cr: After proper heat treatment process, it can also achieve good mechanical properties and have high strength and toughness.

SB121 Side Bolts Advantages:

Compact and adaptable: The short screw design reduces the overall length of the machine and concentrates the center of gravity, making it particularly suitable for use in space-constrained environments, such as urban demolition and narrow alleyway construction.

Improved response speed and impact frequency: Due to the shorter transmission path and more direct energy transfer, the impact frequency of the hydraulic breaker can be increased (up to 300–450 bpm), thereby improving crushing efficiency.

Reduced wear and failure rate: The short screw structure reduces the force arm length of moving parts, reducing the risk of wear caused by off-center loading. Combined with the SB121's overall triangular shell design, this enhances the stability and durability of the equipment.
