A2FE63 Rexroth Hydraulic Motor - Mobile-Grade Fixed Displacement Power

The Bosch Rexroth A2FE63 is a fixed displacement bent-axis piston motor that balances strong torque with compact dimensions. It is built for the demanding duty of mobile machines and industrial drives where starting power and reliability decide productivity.

Below you will find the full picture: technical data, advantages, selling points, target industries, typical equipment and the answers to the eight questions buyers ask most.

Product Introduction

With 63 cm³ of displacement per revolution, the A2FE63 delivers the middle-weight torque class of the A2FE family: powerful enough for heavy starts, compact enough for vehicle chassis layouts. Its fixed displacement character keeps the hydrostatic circuit simple and the output predictable.

Every unit is supplied as a complete motor ready for integration. Technical values stated here follow the Bosch Rexroth RE 91053 documentation; exact figures depend on the selected order code and should be verified with our team before production.

Frequently Asked Questions

Q1. Which mounting and shaft options are available?

The A2FE63 offers several standard flange and splined shaft codes. Send us your machine interface drawing and we will confirm the matching variant.

Q2. Which industries commonly use the A2FE63?

Construction, agriculture, material handling, municipal vehicles, quarrying and recycling machinery all use this size class for travel and auxiliary drives.

Q3. Does it suit closed-loop hydrostatic circuits?

Yes. The fixed displacement design works well in both closed-loop and open-loop circuits; a case drain connection is recommended.

Q4. How does it handle shock loads?

It tolerates pressure peaks up to 400 bar. A correctly sized case drain line protects the shaft seal during shock events.

Q5. Is there a minimum order quantity?

Stock items can be ordered singly; volume pricing applies from higher quantities. Contact us for a program quote.

Q6. What is the operating temperature range?

Typical ambient range is −25 °C to +80 °C. Fluid temperature limits depend on the seal and fluid selection.

Q7. Do you provide technical documentation?

Yes - catalog excerpts, dimensional drawings and test reports are provided with each order.

Q8. What export documents do you supply?

Commercial invoice, packing list, bill of lading and certificate of origin are provided; other documents on request.
