Description
Hytek HA2FM axial piston motors are fixed displacement motors with bent axis design, built for hydrostatic transmissions in both open and closed circuits. They are imported by Hydraut, the official Hytek importer, and supplied by Interfluid from stock with full technical support.
They are available with keyed and splined shafts and stand out for their high power density and excellent starting torque efficiency.
The Hytek HA2FM is a versatile high-pressure motor, ideal for many applications thanks to its wide range of displacements, from 10 to 200 cm³. Effective both at start-up and in operation, the HA2FM works in open and closed circuits.
Versions with an integrated pressure relief valve are available on request.
With a nominal pressure of 400 bar and a peak pressure of 450 bar, the HA2FM is the interchangeable alternative to the Rexroth A2FM series: see the interchange table below.

Rexroth A2FM alternative: Hytek HA2FM interchange table
Looking for a Bosch Rexroth A2FM fixed displacement axial piston motor? Hytek HA2FM motors, imported by Hydraut, are the interchangeable alternative to the A2FM series 61 and 63: the HA2FM code is the A2FM type code with an H prefix (for example, A2FM63/61W-VAB010 becomes HA2FM63/61W-VAB010).
Displacements available: 10, 12, 16, 23, 28, 32, 45, 56, 63, 80, 90, 107, 125, 160, 180 and 200 cm³. Search the table by Rexroth material number (R902…) or type code, then request a quote: our technicians will confirm the equivalent for your application.

Frequently asked questions
Which sizes and pressures does the HA2FM series offer?
The Hytek catalogue covers sizes from 23 to 180 cm³/rev. Rated pressure is 400 bar with a 450 bar peak on series 63 with A/Z shaft (350/400 bar with B/P shaft); series 61 and 69 are rated 300 bar.
What is the difference between series 61, 63 and 69?
Series 61 and 63 have 7 pistons, at 30 and 40 MPa respectively, from size 23 to 160. Series 69 has 9 pistons, 30 MPa, size 180.
How do I request an HA2FM motor?
Send us the Hytek code (for example HA2FM63/61W-VAB020) and the quantity through the contact form: a technician will reply with price and availability within 24 working hours.
What data is needed to identify the motor to replace?
The motor code or the nameplate data is enough; if available, also give the Rexroth material number. Our technical office will indicate the most suitable HA2FM version: size, series, shaft, ports and valves.
Which valve options are available?
One- or two-stage relief valve with 50–420 bar setting, flushing valve and BVD counterbalance valve. Combinations depend on the size: please give us the complete code.
Which shafts and flanges are available?
DIN 5480 splined shaft or DIN 6885 keyed shaft (SAE J744 only on size 45), 4-bolt flange ISO 3019-2. Combinations vary by size.
