There is no SR limit, But when UE sends SR then ENB should send reply otherwise UE will send unlimited SR to ENB , so to avoid this situation UE will do MAX SR retransmission's, once max SR re transmission is reached then UE will release SR configuration and will do rach.

In the above scenario after releasing SR configuration UE will not have any SR configuration.

LTE: How does eNodeB enforce uplink data rate and what eNodeB does in case when UE is not following the uplink limit ?

This is not a usual case. Assume an eNodeB has multiple bearers (GBR and non-GBR) with the UE, eNodeB enforces subscribed downlink data rate by using the different scheduling algorithm. Can eNodeB reject the uplink grant assuming UE is crossing its subscribed limit ?
