The BKY2 hydraulic travel drive combines a hydraulic motor with a reduction gearbox to provide controlled output speed and torque for mobile machinery. The supplied model range includes five configurations with rated output torque from 950 to 2,200 N·m, a listed reduction ratio of 5.75 and BM5 hydraulic motor options. Select the appropriate unit according to machine weight, required travel speed, hydraulic system conditions and mounting dimensions.
Integrated hydraulic drive: The motor and reduction gearbox provide hydraulic power transmission and speed reduction in a compact assembly. Check the installation interface and hydraulic connections against the host machine before ordering.
Multiple torque configurations: The listed BKY2 models cover rated output torque from 950 to 2,200 N·m and maximum output torque from 1,200 to 3,000 N·m.
Defined reduction ratio: The supplied specifications list a reduction ratio of 5.75 for all five models. Confirm the required output speed and operating range for the specific application.
BM5 hydraulic motor options: The model table lists BM5-80, BM5-100, BM5-125, BM5-160 and BM5-200 motor configurations. Confirm the exact motor model, displacement, hydraulic pressure limits and port arrangement before purchase.
Application-specific selection: The supplied product information lists excavators, loaders, drilling rigs and agricultural machinery as potential applications. Compatibility must be evaluated for the actual equipment model and operating requirements.
The table below reproduces the supplied model data. Values are listed for technical comparison; confirm the final configuration and operating limits with the approved product datasheet before installation.

Specification notes: The machine-weight ranges shown above are the values supplied for each model, not the weight of the travel drive itself. The listed gross weight is 28 kg for all five variants. Confirm this figure, the speed range, pressure ratings and model codes against the current technical datasheet before purchasing.
Choose a travel drive according to the equipment's actual operating requirements rather than model name alone. The following information helps confirm whether the selected configuration is suitable.
Equipment model and operating weight: Provide the machine type, model and approximate operating weight.
Required output torque and speed: Confirm the required travel performance, load conditions and operating cycle.
Hydraulic supply: Specify system pressure, available flow rate and required motor direction.
Installation dimensions: Provide the mounting drawing, port arrangement, shaft or spline details and available installation space.
Motor configuration: Confirm whether the required model uses the listed BM5 motor and whether the motor is included.
Working environment: Describe ground conditions, duty cycle and expected external loads.
For replacement applications, compare the full model code, mounting interface, hydraulic port locations, shaft or spline dimensions, reduction ratio and pressure requirements. Similar model names alone do not establish direct interchangeability.
Customization and OEM services are listed as available in the supplied product information. Send the target equipment model, technical drawing, installation dimensions and hydraulic requirements to confirm the available configuration. Final specifications should be approved before production.
Payment terms: The supplied terms list a 30% deposit and 70% balance before shipment, generally by T/T. Confirm the agreed payment schedule in the sales contract.
Lead time: The listed delivery time is 20–25 days after receipt of payment. Confirm the current lead time for the selected model and order quantity.
Technical support: The supplied product information lists 24-hour online service and overseas technical service. Confirm the service scope and availability for your equipment and destination.
The following image is retained from the original page. Its filename identifies a Rexroth GFT36 final drive, so confirm that it belongs on this BKY2 product page before publication.
The supplied product information lists excavators, loaders, drilling rigs and agricultural machinery as potential applications. Confirm that the selected model meets the machine's weight, travel, hydraulic and mounting requirements.
OEM and customization services are listed as available. Provide the equipment details and technical drawing so the required configuration can be evaluated.
Do not assume direct interchangeability from the model name alone. Confirm mounting dimensions, shaft or spline details, hydraulic ports, reduction ratio, pressure limits and the complete assembly configuration before selecting a replacement.
The supplied product information lists a one-year after-sales warranty. Confirm the warranty start date, coverage and exclusions in the written warranty terms.
The supplied product information lists a minimum order quantity of one set. Confirm availability and the order terms for the selected configuration.
To request a quotation, provide the complete model number, equipment model and operating weight, required travel speed, hydraulic pressure and flow, and mounting dimensions. Confirm the technical drawing and final configuration before placing an order.
