Frequently Asked Questions
Q1: What is the main difference between your 40H PU coupling spider and the traditional rubber coupling spider?
A1: Our product adopts high-performance PU polyurethane material, which features 3-5 times higher wear resistance, excellent oil resistance, low compression deformation and strong anti-fatigue performance. It effectively avoids swelling, aging and cracking problems common in rubber products under long-term heavy load conditions.
Q2: What equipment is the 40H PU coupling spider suitable for?
A2: This 40H PU coupling spider is widely applicable to full series of excavators, rotary drilling rigs, wheel loaders, heavy-duty hydraulic pump stations, mining auxiliary equipment and various industrial heavy machinery transmission systems.
Q3: Does the PU coupling spider need any modification during installation?
A3: No modification is required. Our 40H PU coupling spider strictly follows the original standard size of 40H series coupling accessories and is a direct plug-and-play replacement for original rubber couplings.
Q4: What is the working temperature range and load capacity?
A4: The operating temperature ranges from -35℃ to +95℃. The nominal torque reaches 600Nm, and the maximum surge torque is upgraded to 1750Nm, providing stronger load stability than ordinary rubber couplings.
Q5: Do you support small trial orders and mixed batch orders?
A5: Yes. The minimum order quantity is 2 sets, supporting small trial orders. We also support large batch wholesale orders and provide exclusive bulk discount policies for long-term cooperative customers.
Q6: What is your delivery time and shipping method?
A6: In-stock products can be shipped within 1-2 working days after payment. For large customized bulk orders, the production and delivery cycle is 15-30 working days. We support global shipping methods including sea freight and air express.
Q7: What payment terms do you accept for overseas customers?
A7: We support multiple cross-border payment methods including Western Union, Cash, Bank Transfer, PayPal, HSBC and CITY BANK international transfers.
Q8: What are the advantages of PU material in heavy-duty construction scenarios?
A8: Professional customized heavy-duty PU material has excellent anti-aging, anti-abrasion and anti-oil swelling properties. It resists severe vibration, torque impact and dust erosion while providing good shaft misalignment compensation and vibration damping effects.
Q9: How do you guarantee product quality and after-sales service?
A9: All PU coupling spiders undergo strict dimensional inspection, hardness testing and surface quality screening before shipment. We provide professional technical support and after-sales response service within 24 hours.
