Product detail · 详情说明
The elastomer spider is the wearing part: replacing it restores the coupling without replacing the hubs. Choosing spider hardness is a real engineering decision — a soft spider absorbs more shock but allows more wind-up, a hard one transmits torque more rigidly.
Specify both shaft diameters, keyway sizes, motor power and speed, and whether the application reverses. We then confirm the coupling size and spider hardness from the rating table rather than from a nominal bore alone.
选型与验收要点 / Selection & acceptance points
- Replaceable spider keeps hubs in service
- Multiple elastomer hardnesses for shock vs. torsional stiffness
- Pilot-bore hubs can be finish-machined to your shaft at destination
- Size selected from torque and speed, not from bore diameter alone

Frequently Asked Questions
Send the part number, a photo of the nameplate / old part, or the machine model and required dimension. We reply with the applicable standard designation and a factory datasheet; the final specification is fixed on the proforma invoice.
Commercial invoice, packing list, certificate of origin, bill of lading or AWB, and an HS-coded technical datasheet. The HS 6-digit heading shown on this page is the international classification; your clearing agent confirms the Pakistan 8-digit PCT subheading and the duty rate applicable on the date of import.
No. The location named under 'Typical sourcing base' is a publicly known industrial cluster, given to help you understand the supply chain. The actual factory, country of origin and any mill / test certificate are confirmed in writing on the quotation and the certificate of origin. Treat it as [待确认] until then.
