Does using medium carbon steel versus ductile cast iron for support unit materials affect performance?

HZMotion mainly uses medium carbon steel for support units, with only the SBK type bearing housing made of ductile cast iron. The mechanical properties of these two materials are very similar, so there is no difference on performance.

What is the recommended lubrication grease replenishment interval for the bearings inside the support unit?

We add an appropriate amount of grease to the bearings before shipment. The grease replenishment interval varies depending on the operating conditions and environment. Generally, it is recommended to perform maintenance and inspection once every quarter.

AI-Powered supplier vetting

SummaryHZMotion - Shandong Huazhun Machinery Co., Ltd. is an industrial machinery supplier established in 2010, with stated activities covering industrial robots, intelligent robots, gears, transmission components, CNC machines, and related mechanical equipment. It reports OEM service for well-known brands, ISO9001:2015 and ISO14001 certifications, inventory availability, and established service procedures for complaints, corrective actions, and supplier assessment. Its export history is stated as 10 years, although exports represent only 1%–10% of total sales. The supplier reports no available SDK, no new products launched in the past year, one R&D engineer, no Fortune 500 cooperation, no overseas warehouse or showroom, and no valid manufacturing-capacity contract with associated subcontractors. The provided financial records identify 2022–2024 periods but do not provide financial performance values, so financial credibility cannot be determined.

Supplier typeThe supplier is a machinery and precision motion technology manufacturer and seller. Its stated scope includes industrial and intelligent robots, gears and transmission parts, CNC machines, bearings, mechanical components, and related R&D, while its company description emphasizes precision transmission and positioning components.

CertificationsThe supplier reports ISO9001:2015 and ISO14001 certifications, and its description also records earlier ISO9001:2008 and ISO14001:2004 certifications. These statements provide explicit evidence of management-system certification, although the provided slices do not show certificate validity dates or scope.

After-Sales capabilityThe supplier reports written procedures and records for service-capability assessment, corrective and preventive actions, and customer complaint handling. It also has in-stock service capacity, but lacks overseas warehouse and showroom capabilities; therefore, the evidence supports structured service processes but not comprehensive overseas support.

Production capacityThe supplier states that it independently manufactures industrial robots, components, gears, transmission parts, and CNC machines, and maintains ready-to-ship inventory. However, it reports no valid manufacturing-capacity contract with associated subcontractors, so the evidence supports direct manufacturing and inventory capability but not subcontractor capacity assurance.

Customization capabilityOEM service for well-known brands is explicitly reported, and the supplier conducts R&D and manufacturing across precision transmission, positioning components, robots, CNC machines, and mechanical equipment. This directly supports the ability to provide customized or OEM products, although the slices do not specify customization scope, engineering workflow, or delivery performance.

Product Q&A

Q:Can the integrated motor bracket be used immediately after being taken out of the packaging?

Yes. The bearings in the integrated motor brackets are pre-lubricated and properly preloaded. No additional operations are required before use.

Q:Is it possible to replace only the bearings in the ball screw support units or the integrated motor brackets?

If a bearing failure occurs, a repair kit can be ordered for replacement. However, since the bearings and related components require precise installation, we recommend replacing the entire assembly to ensure optimal performance.

Q:What raw material is used to manufacture the lock nuts?

The NRA series is made from C45 material, while the NR/NF and NK series use 42CrMo material.

Q:What is the precision grade of the lock nut threads?

All lock nut threads in the HZMotion series are ISO 4H grade.

Q:Which standard is used as the basis for the design of each nut bracket product series?

The MC series is interchangeable with THK products, the MGS series is compatible with Rexroth products, the MGD series corresponds to the DIN 69051-part 5 standard, and the NH series is a proprietary HZMotion line compatible with most ball screws on the market.
