TRIO17001140 — Head and Main Shaft Assembly (Short Head) for TC84X Cone Crusher. This is the rotating head-and-shaft assembly of the short-head version of the TC84X cone crusher, produced as a direct-fit after-market replacement for the OEM assembly. It carries the mantle and provides the eccentric-driven crushing motion; all major castings, forgings and welds are heat-treated and UT-checked before dispatch.

The assembly reference number (TRIO TRIO17001140) corresponds to chapter 1.6 HEAD AND MAIN SHAFT ASSEMBLY of the TC84X Parts Manual and contains 7 line items as listed below. Each part can be supplied individually or as a complete short-head main-shaft assembly; please quote the TRIO part number(s) when ordering.

Aftermarket replacement parts compatible with TC84X cone crusher. Not affiliated with or endorsed by the original equipment manufacturer.

Typical Applications

The TC84X short-head main-shaft assembly is used in secondary and tertiary crushing circuits where a finer product gradation is required. Compared with the standard (coarse-cavity) head, the short-head profile produces a higher proportion of finished-size particles in a single pass, making it the preferred cavity for:

Hard-rock aggregate production (granite, basalt, diabase, gneiss)
Iron-ore and copper-ore beneficiation plants (fine crushing stage)
Recycled-aggregate and construction & demolition (C&D) processing lines
Cement and lime-stone preparation circuits feeding ball mills

The head and main-shaft assembly is the rotating heart of the crusher and works in conjunction with the bowl assembly (chapter 1.7, TRIO5007838) to set the closed-side discharge opening. Inspection of the head casting, main shaft and mainshaft cap is recommended every 2,000 operating hours or whenever the mantle is replaced.

Frequently Asked Questions

Q1. What material is the main shaft (TRIO17001147) made of?
Forged from 40CrNiMo alloy steel, quenched and tempered to a typical hardness of 280–320 HB. Ultrasonic testing (UT) is performed on every forging before machining, and a test certificate is shipped with the part.

Q2. Can CASTEEL supply the head casting (TRIO17001142) and the cap (TRIO17001146) separately?
Yes. Both items are available as individual castings, with or without finish-machining. We can also supply them as a matched pair already fitted with the seal ring.

Q3. Is this assembly compatible with both TC84X and TC84XR models?
Yes. TRIO17001140 is the short-head main-shaft assembly for the TC84X platform; the same assembly fits the equivalent TC84XR model year — the TC84X / TC84XR naming is a commercial designation only. When ordering, simply quote the TRIO part number(s) shown in the table above.

Q4. What is the typical lead time?
Standard lead time is 30–45 days for castings + 15–20 days for machining. Stocked main shafts and caps can be dispatched within 7–10 working days for urgent breakdown orders.

Q5. Do you provide a quality / test package?
Yes. Every shipment includes the material test certificate (MTC), UT report, dimensional inspection report, and a warranty certificate. Third-party inspection (SGS, BV, TUV) can be arranged on request.
