42CrMo CAT B Breaker Front Head Heavy Load Chisel Holder Housing For Excavator Demolition Hammer

CAT B series hydraulic breaker front head, also called chisel holder or front housing, is a key load-bearing front assembly component for CAT B medium hydraulic breakers covering all models B12 to B90. It holds the front guide bushing and cooperates with rod pin to fix the chisel, widely applied in municipal demolition, road renovation, landscaping and medium quarry secondary crushing works.

Manufactured with solid 42CrMo alloy steel through one-piece forging and stress relief heat treatment. Thickened wall structure delivers outstanding anti-impact and anti-deformation capacity to cope with long-time high-frequency striking loads.

All pin holes, bushing installation cavity and connecting bolt positions are precisely CNC machined to match OEM assembly standards. After locked with main cylinder via through bolts, it forms a complete stable front working unit to reduce equipment vibration and abnormal wear.

Every front head undergoes flaw detection, pressure load test and assembly matching inspection to meet original equipment interchange standards. Full model stock supports small retail maintenance orders and large bulk wholesale for construction contractors and machinery rental firms. Custom size and surface anti-rust processing service can be provided for global machinery repair factories and spare parts dealers.
