Product Details

Main Drive Rubber Block (Elastic Element OEM 910284602)

This rubber block is the core elastic component of BHS mixer main drive coupling. It connects the power output end and the mixing shaft flange. Under continuous heavy alternating load, it buffers impact force and avoids rigid collision between metal parts. Natural rubber version suits normal working environment; PU option offers better oil resistance and longer service life under heavy load.

Synchronous Coupling Flexible Connection Assembly

The flexible connection set includes multiple rubber blocks installed on the synchronous coupling. It keeps the twin mixing shafts running synchronously while absorbing instantaneous impact. Aging, cracking or compression set of rubber blocks will lead to abnormal vibration, loud noise and even damage to gearbox.

Application & Compatible Models

Suitable for BHS DKX, DKXS series twin shaft concrete mixer:

• BHS DKX 3.0
• BHS DKX 4.0
• BHS DKX 4.5
• BHS DKXS 3.0
• BHS DKXS 4.0
• BHS DKXS 4.5

Ordering Tip: Please provide mixer nameplate serial number, OEM part number, or send photos of your old rubber block for accurate matching.

Maintenance & Replacement Guidance

1. Regularly inspect rubber surface for cracks, swelling and permanent deformation.
2. Replace the rubber block immediately if abnormal vibration or impact noise occurs.
3. When installing, evenly tighten bolts, avoid uneven stress on rubber element.
4. Keep away from long-term oil soaking and high temperature environment to extend service life.

FAQ

Q1: How to confirm if this rubber block fits my BHS mixer? A: You can check OEM number on old spare part, provide mixer serial plate information, or measure the hole dimension and send photos to us for verification. This part OEM 910284602 is for BHS DKX/DKXS 3~4.5m³ twin shaft mixer.

Q2: What is the difference between natural rubber and PU material? A: Natural rubber has good elasticity and cost advantage for general use. PU material features superior oil resistance, wear resistance and longer working life under heavy load.

Q3: What are common failure symptoms of rubber coupling block? A: Surface cracks, permanent compression deformation, mixer abnormal vibration, knocking noise during operation, gearbox overload.

Q4: Can you make customized non-standard rubber coupling blocks? A: Yes. We can produce according to your physical sample or CAD technical drawing.
