Import Ceramic Guide Wheel — Buy in Bulk from Supplier in China

The Ceramic Guide Wheel offered by Ruigu Precision Ceramic Parts Co., Ltd. is machined from silicon nitride, a ceramic material known for its exceptional wear resistance. Silicon nitride provides a combination of high strength and low density, which reduces the rotating mass in precision motion systems. The wheel is designed to maintain dimensional stability across a wide temperature range, offering thermal stability up to typical operating limits of ceramic components. According to the supplier’s listing, the wheel’s surface treatment minimizes friction, extending the service life of the guided equipment.

In the broader market, ceramic guide wheels are commonly supplied with diameters from 20 mm to 200 mm and a diameter tolerance of ±0.02 mm. Typical Vickers hardness values for silicon nitride wheels lie between 1500 HV and 1800 HV, while the bulk density is around 3.2 g cm‑3. Standard specifications also include a maximum continuous operating temperature of approximately 1200 °C and a thermal conductivity near 30 W m‑1 K‑1. These typical parameters align with the performance claims made by Ruigu, indicating the product meets usual industry expectations for precision guide components.

The wheels are suited to automation, robotics, aerospace and automotive manufacturing where accurate linear or rotary guidance is required. Buyers such as system integrators and OEMs often request bulk quantities, and the supplier notes that flexible minimum order quantities are available to accommodate both prototype and mass‑production needs. Shipping can be arranged under FOB or CIF terms, with packaging designed to protect the fragile ceramic parts during transit. Prospective importers should verify the exact dimensions, tolerance and certification documents with Ruigu before finalising the order.

Ruigu Precision Ceramic Parts Co., Ltd. is located in Dongguan, Guangdong Province, China, with the address listed as Guancheng Peak, Dongguan 523013. The company holds a harbour‑level trust tier on the platform, but its response rate is recorded as 0.00 with no recent response hours, indicating that buyers should proactively initiate contact and confirm communication availability. The supplier’s profile focuses on the production of precision ceramic components, and the listing specifically highlights ceramic guide wheels as part of its catalogue.

The supplier references ISO and SGS certifications for its products, though the listing does not provide copies of these certificates; interested buyers should request the latest certification documents to verify compliance. Packaging is described as protective, intended to safeguard the ceramic wheels during transport, and the company offers both FOB and CIF shipping options.
