Famous IMU manufacturers include Invensense, Bosch, and Analog devices. All of them provide easy-to-use evaluation boards, so it is a good idea to use them first.

Any of these IMUs should be able to provide angular velocity. However, it is difficult to get the position. IMU usually consists of a combination of gyro and accelerometer (+ magnetometer). Ideally, the position can be obtained by integrating the acceleration twice, but in practical use, the output bias is too large and the twice integrated value is far from the actual position. If you need accurate position information, you may want to consider using other sensors, such as camera position estimation, ultrasonic or laser ranging sensors, etc.

Thanks for the answer Takashi Basically we want the IMU sensor which provides the position tracking and angular velocity feature so that by using that we can get the position and angular velocity as well.

Takashi Ozaki listed a good number of manufacturers of low-cost IMUs. He also correctly pointed out that in practice you cannot do an estimation of position from IMUs. What is your application?
