Joint does not stop sliding

edit

Hi, I have created a model of the sliding door in gazebo. This is the code:

<?xml version="1.0" ?>
<robot name="door_balcony">

  <gazebo reference="base_bac">
    <material>Gazebo/GrassFloor</material>
  </gazebo>
  <link name="world"/>
  <joint name="link_joint_bac" type="prismatic">
    <axis xyz="-1 0 0"/>
    <parent link="world"/>
    <origin rpy="0 0 1.57" xyz="10.615 6.25 1.06"/>
    <limit effort="10.0" lower="-0" upper="0.8" velocity="0.5"/>
    <child link="link_bac"/>
    <dynamics damping="1" friction="10"/>
  </joint>
  <link name="link_bac">
    <inertial>
      <mass value="10"/>
      <origin xyz="0 0 0"/>
      <inertia ixx="1.0" ixy="0.0" ixz="0.0" iyy="0.1" iyz="0.0" izz="0.1"/>
    </inertial>
    <visual>
      <origin rpy="0 0 0" xyz="0 0 0"/>
      <geometry>
        <box size="0.8 0.06 2"/>
      </geometry>
    </visual>
    <collision>
      <origin rpy="0 0 0" xyz="0 0 0"/>
      <geometry>
        <box size="0.8 0.06 2"/>
      </geometry>
    </collision>
  </link>
  <gazebo reference="link_bac">
    <material>Gazebo/RustySteel</material>
    <turnGravityOff>true</turnGravityOff>
  </gazebo>
</robot>

When I apply the joint effort it starts sliding from lower to higher limits.

rosservice call gazebo/apply_joint_effort '{joint_name: link_joint_bac, effort: 1, start_time: 10000000000, duration: 100000000}'

But when delete the joint force right at the time when the door is fully open, It does not stop sliding.

rosservice call gazebo/clear_joint_forces '{joint_name: link_joint_bac}'

Is there a mistake in my understanding or code ? Is there any other way to start and stop joint motion in gazebo ?

Thanks!
