I have to run a job in production; the volume of record which will be extracted is expected to be high (in the order of millions). I don?t want the job to abend due to lack of space. Can someone suggest me what can be the maximum space allocation for a PS dataset in terms of cylinders?

How many records and how many bytes for each?
Once you know the above and what model of dasd you have available for use, the amount of space can be calculated. Once you know the amount of space needed, your storage management people can tell you if there is enough space for your run.
One important thing to consider is whether this file is to be kept for future use or if it is a transient file (used a short time and diacarded when the process(es) using it are succesfully completed (i.e. month end).
