Mcr rexroth piston motor

Buyers must prioritize displacement (cc/rev), maximum pressure (up to 450 bar), and output torque to ensure the motor meets the machine's load requirements. It is critical to confirm the mounting flange type (e.g., wheel mount or shaft mount) and spline dimensions to ensure mechanical compatibility. Additionally, verify the integrated braking system specifications, such as static and dynamic braking torque, which are vital for safety in mobile machinery.

Look for suppliers who utilize high-strength casting materials and precision grinding processes for the cylinder block and pistons. Request 100% factory pressure testing reports and check for ISO 9001:2015 certification. A high-quality motor should demonstrate low noise levels and minimal internal leakage during operation. For long-term reliability, ensure the internal components like bearings and seals are sourced from reputable brands (e.g., SKF or FKM seals).

These motors are primarily used in high-torque, low-speed (HTLS) applications. Common scenarios include skid steer loaders, forklifts, mining machinery, and construction equipment like road rollers. They are also widely applied in marine winches and agricultural machinery where smooth rotation at low speeds and high radial load capacity are required.

For the European market, ensure the product complies with the Machinery Directive 2006/42/EC and carries the CE mark. For North America, adherence to SAE (Society of Automotive Engineers) standards for hydraulic fittings and ports is essential. Additionally, ensure the supplier provides Material Safety Data Sheets (MSDS) for any pre-filled hydraulic oil or protective coatings used during shipping.

Always request a pre-shipment inspection (PSI) by a third-party agency like SGS or Intertek. Use Secure Payment services on Made-in-China.com to ensure funds are only released after the goods are verified. Ask the supplier to provide a video of the motor undergoing a bench test showing the serial number and real-time pressure gauges before crating.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate bulk discounts (typically 10-20% for 50+ units) and ask for spare parts kits (seals and bearings) to be included in the initial order. For lead times, establish a penalty clause for delays exceeding 15 days to ensure the supplier prioritizes your production slot.

Hydraulic motors are heavy and sensitive to moisture. Insist on vacuum-sealed plastic packaging and anti-rust oil coating on all exposed shafts and ports. The motors must be secured in fumigated wooden crates (IPPC standard) with internal bracing to prevent movement during sea freight, which could damage the precision-machined surfaces.

Verify the correct HS Code (typically 8412.29) to determine the exact duty rates in your country. Ensure the Commercial Invoice and Packing List are detailed and accurate to avoid customs holds. If shipping to the US, be aware of Section 301 tariffs on Chinese-made machinery parts and consult with a licensed customs broker to optimize your tax liability.
