Atlas Copco LZB22A049-11 is a compact standard-lubricated vane motor designed to deliver its documented operating point from a regulated compressed-air supply.

The A049 gearing, clockwise-only arrangement and keyed output distinguish it from reversible, lubrication-free and threaded-shaft LZB 22 configurations.

A correct replacement therefore requires the original order identity, shaft geometry, coupling alignment, shaft loading and pneumatic circuit to be checked together.

  • A049 defines the documented speed and torque configuration
  • The standard LZB 22 version requires lubricated compressed air
  • Clockwise-only operation separates it from reversible AR variants
  • BSP 1/8 supply and BSP 1/4 exhaust connections are documented

  • Valve and hose flow capacity must preserve pressure at the motor
  • The -11 suffix identifies the keyed cylindrical output shaft

Description
Atlas Copco LZB22A049-11 is the standard lubricated LZB 22 A049 configuration with clockwise rotation and the documented -11 keyed cylindrical output shaft.

At the catalogue reference pressure of 6.3 bar, the motor is rated at 0.25 kW, 2200 r/min and 1.1 Nm, with 2.0 Nm minimum starting torque, 5000 r/min free speed and 5.3 l/s air consumption.

Selection and installation must match ordering number 8411 0201 29, clockwise rotation, shaft-load code b, keyed-shaft geometry, hose sizing, lubrication and the required operating point.

Technical notes
Atlas Copco LZB22A049-11 is the original standard lubricated A049 keyed-shaft configuration under ordering number 8411 0201 29; do not replace it solely by a later LZB22-L designation without confirming ordering identity, rotation, shaft and performance.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which shaft and coupling details should be checked before replacing Atlas Copco LZB22A049-11?
Confirm the documented 10 mm cylindrical shaft with key, the mating keyway, coupling bore, alignment and shaft-load code b. A motor with a threaded shaft or a different coupling arrangement is not a direct mechanical replacement even if its speed and torque appear similar.
What pneumatic preparation should be completed before commissioning Atlas Copco LZB22A049-11?
Prepare clean regulated lubricated air, verify the BSP 1/8 supply and BSP 1/4 exhaust connections, size the filter, regulator, lubricator, valve and hoses for the required flow, and ensure the exhaust path is unrestricted before the first loaded run.
What must be considered when routing the exhaust from Atlas Copco LZB22A049-11 away from the installation area?
Size the exhaust line and silencer to avoid excessive back pressure, which can reduce motor speed and available torque. Confirm the permitted exhaust arrangement, use adequately sized fittings and piping, and route discharged air safely without restricting the motor outlet.
Can Atlas Copco LZB22A049-11 reverse direction through valve switching?
No. It is listed in the non-reversible clockwise section. Confirm the driven mechanism requires clockwise rotation when viewed from the documented connection-plate reference and use the appropriate non-reversible control circuit.
How should the air system be sized for Atlas Copco LZB22A049-11?
Base selection on the 6.3 bar catalogue operating point, 5.3 l/s rated air consumption, BSP 1/8 supply, BSP 1/4 exhaust and the hose lengths. Undersized filters, valves or hoses reduce pressure at the motor and therefore reduce available speed and torque.
What torque check is important before Atlas Copco LZB22A049-11 is approved for a load?
Compare both the 1.1 Nm rated torque at 2200 r/min and the 2.0 Nm minimum starting torque with the actual operating point. Also verify shaft-load code b because radial and axial loading can limit bearing life even when torque is acceptable.
What should be verified after installing Atlas Copco LZB22A049-11?
Confirm clockwise rotation, coupling alignment, keyed-shaft retention, permitted shaft load, filter-regulator-lubricator operation, supply pressure under load, exhaust flow, speed and abnormal noise before returning the machine to service.
