VOAC bent-axis piston motors use the highly successful spherical piston/socket and ring gear timing pioneered by Volvo Hydraulics. This arrangement permits a light-weight, low inertia piston which does not require the efficiency loss of a hydrostatic balance system. It also allows a high axis angle which contributes to the excellent mechanical efficiency of the design.
Randall Hydraulics has worked with Volvo/VOAC hydraulic products for many years, both in
design of new applications and in servicing and trouble-shooting existing systems.
We hold extensive stocks of spares for the F11/F12 range, together with a selection of new units, and would be pleased to discuss your requirements for a new application, or for repair or replacement of an existing product.
